Re: [ovirt-users] vdsm high mem usage

Hello Michael,

I ran into the issue myself and can confirm restarting vdsm with nfs 
mitgates the issue. I even had a cron job for that

This is what I have done. The easiest way to do so is to set the host in 
maintenance, wait for the migration finishes and then restart vdsm. You 
sould do this only at one host and then wait a while so you do not run 
into OOM on the whole cluster at once.

I can confirm 3.5.3 finally solved the issue for us and VDSM keeps below 
100MB RSS.

I already did so, BZ1262293:

Btw, great that ovirt has its own classification now

Thanks for getting back to me Alon.

here you go, but I did northing apart form changing the profile naming. 
Please note I performed anonymization and replaced my domain with 'corp' 
(as you might have guessed). If this had any side effects I can mail you 
the original logs as well.

please find engine log with debugging on attached. I did a number of 
logins in the logged timeframe as well as engine restarts; and hope it 
is sufficient.

This is the default domain administrator account witch exits in any 
forest. But just in case I created a new domain user just for the 
purpose; same outcome

[ovirt-users] RESTAPI: 'action type cpu profile empty' if more then one profile defined in the cluster

2015-08-20 Thread Daniel Helgenberger

Hello,

I still seem to have an issue in ovirt with a [BZ1160846].
In my case, foreman is unable to add hosts if I have multiple CPU
Profiles defined in the cluster:

Failed to create a compute oVirt (oVirt) instance $hostname: action type
cpu profile empty

BZ says this was resolved in RHEV 3.5.1; but running 3.5.3 I still have
this issue (if this BZ is even applicable)

Thanks!

Re: [ovirt-users] [ATN] LDAP Users please read

Hello LDAP Users,

If you migrated from 3.4 or if you used engine-managed-domains to add LDAP
support into engine - this message is for you.

In 3.5 we introduced a new LDAP provider[1][2], it is superset of the
previous implementation, highlights includes:
* Better response times.
* Simplicity, Use of LDAP protocol only - kerberos is no longer needed.
* More LDAP implementations are supported.
* Flexible configuration, can be customized on site to support special
setups.
* Supportability, better logs and feedbacks to enable remote support.
* Variety of fallback policies, examples: srvrecord, failover, round-robin
and more.
* Active Directory: supports multiple domain in forest.

In 3.5 the previous LDAP provider is marked as legacy, users' issues will be
resolved by migration to the new provider.

Upgrade to 4.0 will not be possible if legacy provider is being used.

The new provider is working without any issue for quite some time, we would
like to eliminate the remaining usage of the legacy provider as soon as
possible.

A tool was created[3] to automate the process, it should perform everything
in safe and automatic process, while enables customization if such required.
The one prerequisite that we could not automate easily is obtaining the CA
certificate used by the LDAP server to communicate using SSL/TLS, you should
acquire this manually and provide it as parameter.

We (Ondra CCed and I) will help anyone that is experiencing issues with the
process, please do not delay migration to the point it becomes emergency.

Let's define a virtual goal -- in 1 month no legacy LDAP usage anywhere.

Regards,
Alon Bar-Lev.

Sorry for the ignorance on my part,

but I tried one more and could not find any qualified docs/howtos on the
new AAA feature.

This readme is the only thing witch comes close so far, but running
Engine 3.5.3 at least my installation is missing

/usr/share/ovirt-engine-extension-aaa-ldap*/examples

Does the tool run without them?

As for my part, I only need engine authentication domains; I used:
engine-manage-domains add --domain ...

Should I migrate to the new provider?

Thanks;

 There were no issues with the upgrade that I could see.

 It seems like between 2015-06-19 and 2015-07-01 you ran a 3.4 engine with 3.5 
 reports. Is this possible? To verify, please check/post all setup logs 
 (/var/log/ovirt-engine-setup/*) and /var/log/yum.log.

 I now briefly looked at our spec files and this does not seem to be blocked, 
 so should probably be filed as a bug. However I can't see how it can be done, 
 except for by following a somewhat complex flow of enabling/disabling 
 repositories etc. while running engine-setup.

 Thanks!

 I found a (resolved but yet not closed) BZ1160846 [1] relating to disk

 Strangely I am unable to find anything in engine.log relating to the

 [1] https://bugzilla.redhat.com/show_bug.cgi?id=1160846

 Hi Daniel,
 there are bugs reported for CPU profile, such as [1].
 If this is indeed the case (profile error) it should appear
 as an error in the engine.log (which may have rotated).
Hello Doron, right you are, I seem to have missed this when I first looked.
Reading the BZ I would rather say this is a Foreman issue and not ovirt 
since rejecting the command is intended?

   I do not have 'standard' (=non ha) hosts; so I cannot tell for
   the
 others but suspect it relates to HE.

 Yes, it's the hosted-engine HA agent which keeps VDSM up so
 host-deploy
 fails on that.
 The capability to re-deploy an hosted-engine host from the Web UI is
 not
 available on oVirt 3.5, it will included in 3.6; please help us
 testing
 it
 on the first beta in  a few weeks.

 By the way, why are you trying to re-deploy an host-deploy host from
 the
 web UI?
 Ok, did not know about that. I use 'Reinstall' from the UI.

 Until now, I thought the best way to update the hosts after new engine
 relases was:
 1- update engine
 2. set host to maintane
 4. yum update on host for latest vdsm
 3- Use reinstall from UI.

 Please advise!

 Running on your HE host:
 # hosted-engine --set-maintenance=local
 waiting for everything to be migrated if needed
 # yum update
 # hosted-engine --set-maintenance=none

 should do the job
 Ok, I see; I think one should restart vdsmd also; IIRC it is not
 restarted in the process?

 If updated it will be restarted by its rpm postscript.

 Ok. However, I still need reinstall for configuration updates like
 gluster / firewall etc.

 RPM should perform intelligent upgrading of packages with configuration
 files at least saving them on conf.rpmsave and alerting if not forward
 compatible. If not, it's a packaging bug.

 Also, hosted-enginge-deploy is using 'reinstall'. How do I work around
 that?

 Sorry, I didn't get it.

 I meant 'Reinstall' does a lot of other things apart from updating
 packages. For instance, what am I supposed to do if I switch on kdump
 integration or gluster on the cluster?

 AFIK this only works with transparently for engine 'Reinstall'.

 Hosted-engine is a special case: it has a lot of advantages

I just make a habit of posting bug links on the ML as well. I see this

If you think this is not right will stop doing so.

 Please do not use multiple channels to discuss the same issue.

 I just make a habit of posting bug links on the ML as well. I see this
 as an 'FYI', since I often miss BZ if not posted on the list Of course,
 further discussion sould continue in BZ.

 Please do not do that. Discuss in list first, then if a bug should be opened 
 you will instructed to do so.
 If you open a bug, avoid discussion in other mediums.

Ok; next time I'll will discuss it here first, like always. This one 
seemed too obvouis for me though; I had it on two hosts..

Cheers!


 Thanks.


 If you think this is not right will stop doing so.

  I do not have 'standard' (=non ha) hosts; so I cannot tell for the 
others but suspect it relates to HE.

Steps:
1. set the host to maintenance
At this point, only the HE datacenter is still mounted:
mount |grep nfs
nexstor01.sec.int.m-box.de:/volumes/ovirt/engine on 
/rhev/data-center/mnt/nexstor01.sec.int.m-box.de:_volumes_ovirt_engine 
type nfs 
(rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=10.11.0.30,mountvers=3,mountport=58144,mountproto=udp,local_lock=none,addr=10.11.0.30)

2. Reinstall host
- Error, host deactivated (Job for vdsmd.service canceled.)

3. A workaround is to shutdown sanlock:

# systemctl stop vdsmd
Job for vdsmd.service canceled.

# sanlock shutdown
# systemctl stop vdsmd

4. Now, host deploy works as expected.

 Ok, I see; I think one should restart vdsmd also; IIRC it is not

 If updated it will be restarted by its rpm postscript.

 Ok. However, I still need reinstall for configuration updates like
 gluster / firewall etc.

 RPM should perform intelligent upgrading of packages with configuration files 
 at least saving them on conf.rpmsave and alerting if not forward compatible. 
 If not, it's a packaging bug.

 Also, hosted-enginge-deploy is using 'reinstall'. How do I work around that?

 Sorry, I didn't get it.

I meant 'Reinstall' does a lot of other things apart from updating 
packages. For instance, what am I supposed to do if I switch on kdump 
integration or gluster on the cluster?

AFIK this only works with transparently for engine 'Reinstall'.

As for the he-setup part; when deploying the first or any additional 
hosts the same routine as reinstall will be triggered - in the 
'Installing host' section.





 Steps:
 1. set the host to maintenance

  I do not have 'standard' (=non ha) hosts; so I cannot tell for the
 others but suspect it relates to HE.

 Yes, it's the hosted-engine HA agent which keeps VDSM up so host-deploy
 fails on that.
 The capability to re-deploy an hosted-engine host from the Web UI is not
 available on oVirt 3.5, it will included in 3.6; please help us testing
 it
 on the first beta in  a few weeks.

 By the way, why are you trying to re-deploy an host-deploy host from the
 web UI?
 Ok, did not know about that. I use 'Reinstall' from the UI.

 Until now, I thought the best way to update the hosts after new engine
 relases was:
 1- update engine
 2. set host to maintane
 4. yum update on host for latest vdsm
 3- Use reinstall from UI.

 Please advise!

 Running on your HE host:
 # hosted-engine --set-maintenance=local
 waiting for everything to be migrated if needed
 # yum update
 # hosted-engine --set-maintenance=none

 should do the job
 Ok, I see; I think one should restart vdsmd also; IIRC it is not
 restarted in the process?

 If updated it will be restarted by its rpm postscript.

Ok. However, I still need reinstall for configuration updates like 
gluster / firewall etc.
Also, hosted-enginge-deploy is using 'reinstall'. How do I work around that?

 Steps:
 1. set the host to maintenance
 At this point, only the HE datacenter is still mounted:
 mount |grep nfs
 nexstor01.sec.int.m-box.de:/volumes/ovirt/engine on
 /rhev/data-center/mnt/nexstor01.sec.int.m-box.de:_volumes_ovirt_engine
 type nfs
 (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=10.11.0.30,mountvers=3,mountport=58144,mountproto=udp,local_lock=none,addr=10.11.0.30)

 2. Reinstall host
 - Error, host deactivated (Job for vdsmd.service canceled.)

 3. A workaround is to shutdown sanlock:

 # systemctl stop vdsmd
 Job for vdsmd.service canceled.

 # sanlock shutdown
 # systemctl stop vdsmd

 4. Now, host deploy works as expected.

 Versions:
 EL7 centos
 ovirt-3.5.2 -3.5.3
 sanlock-3.2.2-2.el7.x86_64
 vdsm 4.14.14 - 4.14.20

Re: [ovirt-users] Need Advice on Hosted Engine installation



On 07.06.2015 21:14, wodel youchi wrote:
 Hi,

 We are installing a new ovirt platform for a client. this is our first 
 deployment.

 we chose Hosted Engine install.

 here is the hardware used and the network configuration used be patient :)

 We have 02 hypervisors for now.

 each sever has 8 nic ports, we will use bonding.

 A NAS with nfs4 for the Engine_VM the ISO and Export domains.

 And iSCSI SAN for the rest of the VMs (Data domain)

 At first we chose as a network configuration:

 10.0.0.X/16 as DMZ (ovirtmgmt will use this network)

 172.16.1/24 as Storage network. we've configured our nfs to export only on 
 this
 network.

 -
 We didn't configure the bonding manually at first, we thought that we could do
 it once the engine is up we couldn't :-(
This should be strait forward, but it's a little 'ovirt' - just think of 
hierarchical structures; a resqource needs to be on the top level to be 
able to assigned to the lower level.
- Datacenter
   - Cluster
  - Host

I'll walk you through the UI way:

1. In Datacenter Tab / logical networks create all the networks you need 
with VLAN tags and MTU. There should already be a ovrtmgmt network, you 
cannot edit this;

2. In the cluster tab, select a cluster and use 'add networks' in the 
logical networks tab, add the appropriate networks to your cluster. Take 
care to select/deseclect required networks and types there ( eg. vm 
networks). If a host is missing a required network (see next step), it 
will not be able to start VMs.

3. In the hosts Tab select a host, then 'setup host networking'

The rest is quite cool drag and drop stuff: if you need a bond, drag the 
interfaces over each other.
Then, a bridge will be created with dragging the unassigned vlans to an 
interface. There, you can also setup (ipv4 only) networks.
Take care to at least assign all required networks!

select validate and save.

Repeat with the remaining hosts.



 for ovirtmgmt, if we create the bond after the engine's installation, we could
 not modify the configuration, error message network in use

 for the storage network, we could't attach this logical network to the nic 
 used
 for the storage, because when we do that we loose the connexion to nfs for the
 VM engine...

 so we had to export the VM engine nfs's share on DMZ and we had to configure
 bonding before starting the hosted engine installation.

 We also configured bonding on storage network, but after the engine
 installation, we couldn't attach this bonding to the logical network Storage,
 error message you have to specify network address if static protocol is 
 used,
 the IP address is specified, it's the IP address of the bonding... :-(

 ---
 Questions:

 - Do we missed anything on network configuration capabilities of ovirt? or the
 hosted engine is really a special case?
 - What is the best way to configure ovirt's Hosted Engine storage?
 - For the rest of the network, do we have to configure bonding and bridging 
 from
 the GUI only? (not manually)

 thanks in advance.

I think it is safe to say if you have a good general performance with 
the storage it also performs well with oVirt.

Therefore it might be the wrong place to ask; however, block sizes are 
only one of many factors in storage domain performance. No one but 
yourself or an expert at your site can answer this for you.

I would direct you to the excellent [iozone] utility witch leverages

Re: [ovirt-users] Move VirtIO disk to External LUN disk

 I have performance issue with the VirtIO disks and like to move it to External
 LUN on the ISCI storage
What version are you using? I assume here 3.5.

Do you want the disk image moved or the *content* of the image moved to 
your iscsi lun so the VM boots off directly from the lun? The first 
thing is quite easy and I assume this:
  to use the ISCSI pathtrought
 How I can do that?
1. connect your LUN to your hosts,

- In the GUI,

2. create a new iscsi Storage domain on it,
3. Shut down the affected VM,
4. Navigate to the disk tap, select the affected disks, right-click -  
move disk (or select several and use the button). In the pop up window, 
select the target storage domain (your new iscsi LUN).

The SPM host will now do the moving using the qemu-img or dd command 
depending on your ovirt version. Note, if the source domain was NFS, 
your images are converted from files to block storage, with all the pros 
and cons.

 So if I understand you correctly you want to reduce the space a thin provision

 Yes

 Is there any others way to reclaim disk space ,
Since thin provision in this case relates to sparse files you cannot 
delete files in the VM and have the disk space reclaimed.

But ovirt since v. 3.5 is using qemu-img to copy disk images. IRC this 
process should very well result in a smaller image. So, just use disk 
move and move the disk images to a new storage domain and it should do 
the trick.

Another quite elegant way might be to use [fstrim]. But is is highly 
depended of your VM config, storage domain, and needs virtio-scsi to my 
knowlage.

Another way to avoid this altogether is to to use a compressing file 
system like ZFS for your storage domain.

  I'm pretty sure that thin provisioned disks can only grow. Once they have
  been expanded there's no way to reclaim that space on the NFS share.

  The only thing I think you can do is create a new thin provisioned disk 
 and
  copy the old data over at the file level, not the block level. Afterwards
you could delete the original disk.

 If a virtual machine has more than one image then I'm not sure how

 Any additional storage I need I handle over NFS directly to the

 Perhaps ovirt doesn't automatically delete secondary images? Either
 way you should be able to delete them manually and reclaim space.

 Hi Daniel,
Hello Vinzenz!

 the oVirt Guest agent service won't start just by installation via yum.
 You have to run service ovirt-guest-agent start
 However IIRC with the next boot of the VM it would start since it is
 getting enabled by default.

 If you deploy the guest agent you have to start the agent explicitly.
 (This behavior is aligned with the Fedora packaging guidelines)

The deployment is done by foreman, the package is installed by kickstart 
directly. When installed, it is enabled.

Yet, after the reboot of the machine, the service is stated by systemd 
but not working. Only after a manual restart can fix this.

However, when I just tried a reboot on a random host it was working... 
So - never mind and thanks ;)

Well, if waiting for 3.6 is not an option (there, v2v integration is a
major new feature [1]) you can use manual v2v command line [2] just as
well. This is non destructive and leaves the original VM intact. Basically:

# virt-v2v -o rhev -osd storage.example.com:/exportdomain --network
rhevm vm-name

The trick is '-o rhev'.

It basically drops the VM from libvirt on your export domain; it worked
quite well for me. It also takes care of installing virtio dirvers in
the image.

There where some pitfalls, though - I can't remember all of them. But
one is of course your old host needs have NTFS write support in some
way; and (at leat a year back) there was no package for the virtio
drivers on CentOS; but they just need to be put in the right place.

should i install the windows guest tools before moving over or once
done? what about having to install the virtio drivers when doing and new
windows vm in order to see the disks, how is this
achieved with an already created kvm image?

no, strangely. I only see the server reset in iLO logs; IML log is clean.

 Hi,
Hello,

thanks for getting back to me.

 If you've had a crash caused by an NMI it can often be a hardware issue.
The first thing I checked is IML logs - nothing there. These machines 
are quite resilient and report almost everything.

The HW diag is fine...


 Maybe worth running some H/W diagnostics.

 Cheers

[ovirt-users] Getting kdump integration to work

2015-05-26 Thread Daniel Helgenberger

Hello,

I followed the feature's page [1] and added to my test hosts the 
following lines /etc/kdump:

fence_kdump_nodes othernode-in-cluster
fence_kdump_args -p 7410 -f auto -i 5

Further, I added a firewall rule on both machines:
-A INPUT -p udp --dport 7410 -j ACCEPT

and restarted kdump.

Yet I get on the engine's side:

2015-05-26 10:41:54,113 WARN

 Subject: [ovirt-users] Getting kdump integration to work

 Hello,

 I followed the feature's page [1] and added to my test hosts the
 following lines /etc/kdump:

 fence_kdump_nodes othernode-in-cluster
 fence_kdump_args -p 7410 -f auto -i 5

 Please don't do this, this is added automatically when you deploy
 you host using oVirt UI with Kdump integration enabled in PM tab
 of the host.


 Further, I added a firewall rule on both machines:
 -A INPUT -p udp --dport 7410 -j ACCEPT

 Same as above, this is needed only on engine hosts and it's done
 automatically during oVirt engine installation.


 and restarted kdump.

 Same as above, this is done automatically during host deploy.


 Yet I get on the engine's side:

 2015-05-26 10:41:54,113 WARN
 [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector]

 Event ID: -1, Message: Kdump integration is enabled for host 'hv02', but
 kdump is not configured properly on host.

 Could you please try to do it properly:

1. Put host to maintenance
2. Enable Kdump integration in PM tab
3. Reinstall the host (click Reinstall when you select the host in Hosts 
 tab)

Thanks! This procedure seem to work, engine reporting kdump as activated.
It was rather unclear to me, since I run hosted engine: After host 
deploy they are in the default state, no PM configured. Hence, kdump 
integration is disabled and will never activate since PM has to be 
configured in the first place to install.

Do you think it is a better idea to always activate kdump in the host 
deploy stage so it can later be activated correctly with PM configured?



 Thanks a lot

 Martin Perina
Cheers!

Re: [ovirt-users] Disable Multipathing?

 Multipath makes mounting HDDs harder not to mention emergency mode and
 device-mapper: table: 253:6: multipath: error getting device
There was a discussion about this quite recently [1]; reading this might 
be inserting, too. The reason for this is the general 'to fit everyone' 
approach of the default multipath.conf.

 I do not have multiple paths to the storage. In my case can i disable
 Multipath - is there a right way to do it or i have to use black
 listing?
You can blacklist everything, no problem. But you need make some changes 
to your mulipath.conf. Please just add the lines and do not remove or 
disable any services:

to the second line (2) in multipath.conf, add

# RHEV PRIVATE

to keep host-deploy from overwriting the file.

Then, somewhere in the file:

blacklist {
devnode *
}

Then, you need to run:
multipath -d -v3

to test (it should now list all devices as blacklisted) and if successful:
multipath

Effectively blacklisting everything while dm-multipah continues to run.

Please note, if you are running oVirt node, you also need to run

persist /etc/multipath.conf

Also, you have to do this on every host in your data centers naturally.

 Hi Daniel,

 I'm cc'ing Eli as we are currently facing issue with fence agents
 regression for passing boolean flags to fence agents.
 Thanks for getting back to me so quickly.

 I looked at man page of fence_ilo2 again and I haven't found
 --tls1.0 option at all.
 Strange? FYI I am running CentOS7.1 hosts; installed fence:
 fence-agents-ilo2-4.0.11-11.el7_1.x86_64

 Here, clearly I have this option. The fence agent itself seems to use
 gnutls successfully:

 # fence_ilo2 -a 10.11.0.212 --username=ovirt -p ** -v -o status
 --ssl-insecure --tls1.0

 Running command: /usr/bin/gnutls-cli --priority
 NORMAL:-VERS-TLS1.2:-VERS-TLS1.1:+VERS-TLS1.0:%LATEST_RECORD_VERSION
 --insecure --crlf -p 443 10.11.0.212

 Ahh, I looked at older version on F20. But I can't find --tls1.0 option
 even on man page for fence-agents-ilo2-4.0.11-11.el7_1.x86_64 :-(

 So if you really see this option, please take a look at the end of man
 page, where you can find STDIN format options names and add it along
 with ssl_insecure to options in Power Management tab of the hosts (instead
 of tls1_0 use what you find in your man page):
Many thanks! Using the STDIN options solved this issue. I finally get:
Test succeeded: on

I am using these options in the options field for the ilo2 fencing module:

ssl_insecure=1,tls1.0=1

Also working:
ssl_insecure=1,notls=1

   ssl_insecure=1,tls1_0=1
True. What still puzzles me is the tls1.0 option. In the my man pages 
the STDIN option ins called 'tls1.0'. Also, can you check wherever you 
have a 'notls' option to force SSL3.0? This also works for me.

I think all the info you gave here, esp. using the stdin binary options 
in a way 'option=0|1' is quite essential to get fenceing working. I had 
a quick look over some man pages and I think all the standard fence 
agents are used in the same manner.
Also, a hint might be in order that old ilo boards can't cope with TLS 
and need it disabled. I think here [1] [2]?

 I put the whole command output below [1]

To specify --ssl-insecure please add following
 into options in Power Management tab of the host:

 ssl_insecure=1
 Thanks for pointing out how to actually use these options.

 options defined in PM tab are used to pass custom settings
 of specific fence agent. In you case please take a look
 at man page for fence_ilo2. I looked there briefly and
 I'm afraid that your parameter is not supported.

 Ok, this command runs fine and uses XML:
 fence_ilo2 -a 10.11.0.212 --username=ovirt -p secret -v -o status
 --ssl-insecure --tls1.0

 However, using options --tls1.0 and --ssl-insecure does not work in the
 engine. What puzzles me: the fence agent seems to use an SSL connection
 and XML; while the GUI wants an SSH port form me?

 There I get the error:
 Unknown options ..

 now I only get
 Test succeeded - unknown (witch actually is not successful)

 Thanks!

 I see that fence_ilo3_ssh and fence_ilo4_ssh should support
 passing that option for SSH connection, so you could try them
 if they work with you fence device.

 Hello,

 to make this short - i need to pass ssh options to get the connection to

 How can this be done? I think the 'options' field is clearly for

 Using this option in .ssh/config works btw.

 Hi,
Hello Simon,

 I was wondering if there was any way of changing the ovirt-hosted-engine VM’s
 RAM retrospectively?
This is done by editing the config file:
/etc/ovirt-hosted-engine/vm.conf

There is a config line 'memSize='
Change it to the appropriate value. Also, you can rename the VM there, 
see 'vmName='.

Please remember, you have to make this change on every HA host.

 If I try and modify the VM in the UI, I get an error:

Hello Fabio,
Thoughts about Adding Storage Luns

As I am new here, I would appreciate some advice about some actions that I
intend to perform, please read.

I have added a LUN to my cluster and, for that task, I had to restart every
node
of it. There was no LUNs before, multipathd was stopped and multipath.conf
inexisted. I was able to log in and manually configure multipath.conf, a
simple
multipathd start was not enough.
In theory this should have been enough. What puzzles me: Until now
host-deploy always activated multipathd and writes a multipath.conf.

Here I strongly recommend to blacklist everything and then only white
listing your vendors. Otherwise your error logs fill up and you cannot
connect any USB stick to the host any more ;)

Then, add RHEV PRIVATE to the second line otherwise it will be
overwritten on every host deploy run.
# RHEV PRIVATE

blacklist {
device {
vendor *
product *
}
}

This is bad idea. If you want to blacklist all devices, you can add this to
vdsm generated configuration.
What can I add?

Vdsm is depending on the defaults set in the defaults section.

I just looked; seems to me this is the default part vdsm is needing?

defaults {
polling_interval5
no_path_retry fail
user_friendly_names no
flush_on_last_del yes
fast_io_fail_tmo5
dev_loss_tmo30
max_fds 4096
}

The problem is there is no blacklisting at all in the default
multipath.conf - at least not in mine.

I know this is a hard thing to do for a general version of the file
witch works for anyone. As for my part I have only very specific devices
/ vendors I want to have in my multipah.conf; so I blacklist everything
and later on add blacklist exceptions like:

blacklist_exceptions {
device {
vendor IFT
product *
}
}

Witch IMHO is (was?) since best practice a long time ago when I created
my configs.

After activating multipathd and editing multipath.conf to your needs you
would actually need to run the 'multipath' command to create the paths. [1]

Sometimes you need to rescan the LUNs, though, esp. if you changed sizes
after activating them.

If this wasn't enough, my double NetAPP ( through an Hitachi ) provided me
with
a not so empty brand new LUN, and the task to add the FCP failed to point
this.
Trusting my double, I spent some precious time searching for different
problems,
until receiving some guidance and do a simple dd if=/dev/zero to the
initial
blocks of the LUN.
IMHO you need to initialize the lun with a partition table at least
(parted). dd will do also.

Consulting the documentation
( http://www.ovirt.org/OVirt_Administration_Guide#Adding_FCP_Storage ) for
this
matters, was not of any help.

So, my questions:

This is the intended behavior? Should I open a ticket?

Should I add a note to documentation to point such behavior? ( i'm about to
)

I think this is not ovirts part but rather dm-multipath. My best guess
would be a configuration error on your part?

Re: [ovirt-users] oVirt Instability with Dell Compellent via iSCSI/Multipath

2015-05-21 Thread Daniel Helgenberger



On 21.05.2015 02:48, Chris Jones - BookIt.com Systems Administrator wrote:
 Another issue may be that the setting for COMPELNT/Compellent Vol are wrong;
 the setting we ship is missing lot of settings that exists in the builtin
 setting, and this may have bad effect. If your devices match this , I would
 try this multipath configuration, instead of the one vdsm configures.

  device {
  vendor COMPELNT
  product Compellent Vol
  path_grouping_policy multibus
  path_checker tur
  features 0
  hardware_handler 0
  prio const
  failback immediate
  rr_weight uniform
  no_path_retry fail
  }

 I wish I could. We're using the CentOS 7 ovirt-node-iso. The
 multipath.conf is less than ideal
I have this issue also. I think about opening a BZ ;)

  but when I tried updating it, oVirt
 instantly overwrites it. To be clear, yes I know changes do not survive
 reboots and yes I know about persist, but it changes it while running.
 Live! Persist won't help there.

 I also tried building a CentOS 7 thick client where I set up CentOS 7
 first, added the oVirt repo, then let the engine provision it. Same
 problem with multipath.conf being overwritten with the default oVirt setup.

 So I tried to be slick about it. I made the multipath.conf immutable.
 That prevented the engine from being able to activate the node. It would
 fail on a vds command that gets the nodes capabilities and part of what
 it does is reads then overwrites multipath.conf.

 How do I safely update multipath.conf?

In the second line of your multipath conf, add:
# RHEV PRIVATE

Then, host deploy will ignore it and never change it.




 To verify that your devices match this, you can check the devices vendor and 
 procut
 strings in the output of multipath -ll. I would like to see the output of 
 this
 command.

 multipath -ll (default setup) can be seen here.
 http://paste.linux-help.org/view/430c7538

 Another platform issue is bad default SCSI 
 node.session.timeo.replacement_timeout
 value, which is set to 120 seconds. This setting mean that the SCSI layer 
 will
 wait 120 seconds for io to complete on one path, before failing the io 
 request.
 So you may have one bad path, causing 120 second delay, while you could 
 complete
 the request using another path.

 Multipath is trying to set this value to 5 seconds, but this value is 
 reverting
 to the default 120 seconds after a device has trouble. There is an open bug 
 about
 this which we hope to get fixed in the rhel/centos 7.2.
 https://bugzilla.redhat.com/1139038

 This issue together with no_path_retry queue is a very bad mix for ovirt.

 You can fix this timeout by setting:

 # /etc/iscsi/iscsid.conf
 node.session.timeo.replacement_timeout = 5

 I'll see if that's possible with persist. Will this change survive node
 upgrades?

 Thanks for the reply and the suggestions.

 Hi Daniel,

 Thank you for your comments!

 Let me clarify some points:

 About LUN:

 IMHO you need to initialize the lun with a partition table at least
 (parted). dd will do also.
 So, the lun, which I was provided with, it was too much blank?
Hehe - I only found writing to them once helps in general. Call it 
superstitous - its the first thing I do with a new lun in case there are 
some 'leftovers'. But indeed it should work without it.


 About multipathd:
 I think this is not ovirts part but rather dm-multipath. My best guess
 would be a configuration error on your part?

 I'm really sorry, I failed to point that my nodes are ovirt-node-iso 
 installations, not generic SO installations with ovirt added to them.
Sorry, I did not use node very much (it lacked some drivers I needed) 
and - because of things like this where I need a persistant change 
(multipath.conf).

 I was able to manually configure the nodes - the question is: this is the 
 expected behavior (manual configuration)?
I'll add Fabian for this question; persistant changes to nodes from 
node.iso are his area of expertise.

 Some of my nodes I just restarted and then they were able to see the LUN 
 correctly without any manual configuration. As oVirt provide an iso for node 
 installation, maybe it is important to point such behavior in the oVirt 
 documentation.
As I said - multipathd should be running by default. If this is the 
case, pathes to the same LUN are detected at statup and mapped 
correctly; no intervention necessary.
In the end you might need some special settings depending on your 
storage, though.

 Cheers!

Re: [ovirt-users] Adding FCP - Request for comments

Hello Fabio,
Thoughts about Adding Storage Luns

As I am new here, I would appreciate some advice about some actions that I
intend to perform, please read.

Here I strongly recommend to blacklist everything and then only white
listing your vendors. Otherwise your error logs fill up and you cannot
connect any USB stick to the host any more ;)

Then, add RHEV PRIVATE to the second line otherwise it will be
overwritten on every host deploy run.
# RHEV PRIVATE

blacklist {
device {
vendor *
product *
}
}

After activating multipathd and editing multipath.conf to your needs you
would actually need to run the 'multipath' command to create the paths. [1]

Sometimes you need to rescan the LUNs, though, esp. if you changed sizes
after activating them.

If this wasn't enough, my double NetAPP ( through an Hitachi ) provided me
with
a not so empty brand new LUN, and the task to add the FCP failed to point
this.
Trusting my double, I spent some precious time searching for different
problems,
until receiving some guidance and do a simple dd if=/dev/zero to the initial
blocks of the LUN.
IMHO you need to initialize the lun with a partition table at least
(parted). dd will do also.

Consulting the documentation
( http://www.ovirt.org/OVirt_Administration_Guide#Adding_FCP_Storage ) for
this
matters, was not of any help.

So, my questions:

This is the intended behavior? Should I open a ticket?

Should I add a note to documentation to point such behavior? ( i'm about to )

I think this is not ovirts part but rather dm-multipath. My best guess
would be a configuration error on your part?

 Subject: [ovirt-users] HE setup failing: Cannot set temporary password for 
 console connection

 Hello,

 a week ago I set up a HE (3.5.2) with no problems; now this fails.

You mean you re-deploy the same host (clean setup), or adding another host?

 I
 suspect storage trouble but cannot pinpoint it. Did someth. change there
 with the recent async release?

 The storage domain is NFS3 via a 1G link to a ZFS storage appliance. The
 export is working quite fast; tested with iozone running for over 24h
 without problems.

 It starts with the Verifying sanlock lockspace initialization phase;
 which lasts about 7min (!).

 In the end it seems sanlock is locking the domain down. I can only get
 it back by stopping sanlock and vdsm.

 Attached is the full vdsm lock.


 Thanks!

[ovirt-users] HE: changing engine storage connection's interface

Hello,

I have just deployed my new hosted engine (3.5.2). Now, after some basic
infra is running, I want to change the NFS connection vdsm is using for
HE's vm.

Please advice me on this procedure:

 1. set global maint.
 2. shutdown HE and all VMs
 3. stop engine-ha
 4. stop vdsm
 5. unmount engine domain
 6. hosted-engine.conf storage= stection
 7. start vdsm
 8. start engine-ha
 9. reconnect storage
10. -- repeat step 3 - 9 for all ha hosts


Thanks!

Re: [ovirt-users] simple virtual disk moving

Hello Pavel,

On Mo, 2015-05-11 at 16:12 +0200, p...@email.cz wrote:
 hello, would I explicitly define interface for only disk moving ??
IMHO the disk move is done by the SPM host using dd or qemu-img (ovirt
3.5+). This process uses the storage connections it has configured. 

 
 Move process takes the first interface from list  ( VM assigned ), but 
 any  interface for moving virtuals ( explicitly defined ).
 
 eg.
 VM moving from A to B - it takes interface defined for moving ( 
 movingLAN )
 but
 moving only simple disk of VM from A to B - it takes default interface 
 from list of assigned LANs
 
 any idea ??

 Hi,
 
 I'm still on 3.5.2 and noticed that I have two OVF_STORE disks. Is this

I think there is one OVF_STORE disk per storage domain; counting any
type...

 
 This might have been caused by one of my tests that made my storage 
 domain unavailable. When I activated the storage domain again I noticed 
 that a lot of VM's I created as part of a pool suddenly reappeared  and 
 I had to delete them again.
 
 Now that I have two OVF_STORE disks, how do I know which one I can remove?
 
 When I list the virtual machines tab on the disks, they both show an 
 empty list.

Re: [ovirt-users] Gluster command [UNKNOWN] failed on server

 Hi, 
 
 I just restart it again, and now start the gluster service before starting

I just had the same problem. 
My unknown error indeed to the fact that glusterd / glusterfsd were
not running.

After starting them it turned out the host setup did not automatically
add the iptables rules for gluster. I added to iptables:

# gluster
-A INPUT -p tcp --dport 24007:24011 -j ACCEPT
-A INPUT -p tcp --dport 38465:38485 -j ACCEPT

Afterwards 'gluster peer status' worked and my host was operational
again.

Hint: Sometimes this is do to gluster itself. Restaring glusterd works
most of the time to fix this.

 
 Thanks

to make this short - i need to pass ssh options to get the connection to

How can this be done? I think the 'options' field is clearly for

Re: [ovirt-users] VDSM memory consumption

2015-03-26 Thread Daniel Helgenberger

Hello Everyone,

I did create the original BZ on this. In the mean time, lab system I
used is dismantled and the production system is yet to deploy.

As I wrote in BZ1147148 [1], I experienced two different issues. One,
one big mem leak of about 15MiB/h and a smaller one, ~300KiB. These seem
unrelated.

The larger leak was indeed related to SSL in some way; not necessarily
M2Crypto. However, after disabling SSL this was gone leaving the smaller
leak.

 Hi,
 
 I also see this on the latest 3.5 version, I'm thinking about setting

I did the same thing. In general, it seems to be a bad idea as it
compromised system stability on the long run. While VMs seem to be fine,
engine does not like this very much.

 I cannot believe that people say they don't have this issue.
This was hard for me to accept as well. I know of Markus Stockhausen and
Seven Kieske, both confirmed the small leak. This might also be some
special other service; though I started out with a minimal install of
Centos 6.
 
 Can someone of the devs dive in maybe ?

   service, memory consuption normalizes, but then it start growing
   again.
  
   I have seen some BZ about vdsm and supervdsm about memory leaks, but
   I don't know if VDSM 4.6.10.8 is still affected by a related bug.
  
   Can't help, but I see the same thing with CentOS 7 nodes and the same

   I'm afraid that we are yet to find a solution for this issue, which is
   completly different from the horrible leak of supervdsm  4.16.7.
  
   Could you corroborate the claim of
  Bug 1147148 - M2Crypto usage in vdsm leaks memory
   ? Does the leak disappear once you start using plaintext transport?
  
   Regards,
   Dan.
 
  I don’t think this is crypto related, but I could try that if you still 
  need some confirmation (and point me at a quick doc on switching to 
  plaintext?).
 
  This is from #ovirt around November 18th I think, Saggi thought he’d found 
  something related:
 
  9:58:43 AM saggi: YamakasY: Found the leak
  9:58:48 AM saggi: YamakasY: Or at least the flow
  9:58:57 AM saggi: YamakasY: The good news is that I can reproduce
  9:59:20 AM YamakasY: saggi: that's kewl!
  9:59:25 AM YamakasY: saggi: what happens ?
  9:59:41 AM YamakasY: I know from Telsin (ping ping!) that he sees it going 
  faster on gluster usage

  I do recall what is the issue Saggi and YamakasY were dicussing (CCing
  the pair), or if it reached fruition as a patch. It is certainly
  something other than Bug 1158108, as the latter speak about a leak in a
  normal working state, with no getCapabilities calls.

Re: [ovirt-users] qcow2 as default disk format

2015-02-04 Thread Daniel Helgenberger

Hello,

AFAIK cow images are currently not configurable via GUI and cannot be 
set as default disk format. IIRC the reason being RAW and sparse are 
providing better performance (until you try to copy a larger disk image...).

However, you can add qcow - disks with ovirt shell and use these images:

$ add disk \
--vm-identifier vm_name \
--provisioned_size size_in_bytes \
--interface virtio \
--name disk_name \
--format cow \
--sparse true \
--storage_domains-storage_domain 
storage_domain.name=storage_domain_name

 Hi,

 I'm afraid that none of these cards will work. IIRC it was explained for
 nVidia approach that it would be necessary to add their closed-source
 code to qemu which is not going to happen.
 You might have better luck with AMD card passthrough approach but I'm
 not sure if GPUs can be passed through qemu/kvm and if so, how the
 GPU-rendered image then gets displayed. So YMMV and don't expect much.

 There is a WIP effort for qemu though that is hardware vendor agnostic -
 it's based on creation of virtual GPU in qemu called Virgil that passes
 3D drawing commands to GPU on host. The project is in initial stage
 though so it won't be ready even for testing for quite some time. FWIW,
 there has been discussion about it on spice-devel in recent days and it
 will be presented on upcoming KVM forum so you can get pretty clear
 picture about its status from these sources.

 HTH,

 David

 Hello,

 There is quite active effort to implement device passthrough (including GPU,
 nics, usb etc.)[1].Physical GPU passthrough can be considered generic PCI
 passthrough
IMHO not quite in case of GPUs. I tested that recently with a 
combination of EL7's new default VFIO support [1]. Two things could be 
concluded working with Windows 7 guests and ATI Fire Pro GPUs:
- 'Old' PCI passthough unstable
- VFIO working and performing better (tested with Cinebench OpenGL [2], 
about 98% of the bare metal performance)

As for the stability, the results with VFIO where better in this case. 
The tricky part seems to be the driver installation in the guest, there 
the mandatory device probe in the installer. While PCI passthough 
resulted in Blue Screens, VFIO went though.

[1] 
https://access.redhat.com/sites/default/files/pages/attachments/rhel_whatsnewrhel7beta_techoverview_.pdf
[2] http://www.maxon.net/products/cinebench/overview.html

which should be ready for oVirt 3.6. As for the vGPU, that will
 depend on technology used - SR-IOV would be supported along PCI passthrough,
 anything else might need additional work on our side.

Re: [ovirt-users] Low cost fencing/stonith devices

2015-01-16 Thread Daniel Helgenberger

Hello Mario,

great you ask that, I am pretty interested myself.

On 16.01.2015 12:31, Mario Giammarco wrote:
 Hello,
 I ask this question again to see if there are some improvements.

 I am searching for a low cost stonith/fencing device for servers or hardware
 that has no ipmi/ilo on board.

 I see that there are some interesting products on the market like ubnt/mfi
 mpower that are controllable power outlets but there is no driver for them.

 In my use case WOL support will be enough (using it with ssh or shared storage
 fencing) but as far as I know WOL is not yet supported in ovirt.

Please see [1] - I enclose Martin: What is the status of the Future 
Enhancements WOL; or better what needs to be done and how can we help?

I think we need a custom fence agent here, WOL in python is easily done 
[3] and the MAC filed could be mapped to one of the configurable items.

Though I find it harder working with the fence_agent concept itself. 
Atm, I did not have time to persue this subjct any futher.


 So is there some fencing device supported in 100/200$ price range?

One option would be networked PDU's [2] (here in Germany, they are 
around 200 Euro), maybe you can get some used ones. I think there is a 
list with supported devices though I cannot find it ATM.

If I get it correctly the idea would be to define the outlet as Power 
Management, and switch it on via PMP. Configure the hosts to boot at 
power restore. The host would be shutdown via SSH anyway; the PM device 
only used for start up.

 Sadly this doesn't work for local storage, while /etc/libvirt/autostart
 would work.

 I know nobody likes local storage, but I guess it would be
 relatively easy to implement. Would it be worth to create an RFE for it?

Never run into the THAT, but would have later on for sure. Thanks for

Re: [ovirt-users] VMs guest with Mac OS X on board

2014-11-19 Thread Daniel Helgenberger

This is an interesting topic, witch might prove not interoperable with 
the oVirt project's approach on things (free software).

So, the short answer here is: No, does not work and might take a (long) 
while to work out of the box in oVirt (if ever).
While it is possible with kernel 3.15 and very new qemu versions, I 
consider it as highly experimental and there are numerous issues [1].
These range from technical (UEFI, SMC...) to licensing issues here. You 
are only allowed to run MacOS on Apple hardware.

IIRC only VM ware has some propitiatory setup witch enables MacOS 
visualization, done (partly) with some support of Apple.

 I trying booting VM with mac os x ISO but it is ending with failed:
 Boot failed: could not read the boot disk
MacOS requires UEFI: Booting it with standard SeaBios is not possible. 
Also, the qemu version you use is likely to old, you need at least 2.1
Then, you need at least two things:
- a patched sea bios version
- to integrate chamelion in some way [2].

If you can manage this, I would be interested in how you got it working!

I would start to try this with standard fedora 20 and kvm.

[ovirt-users] Engine: Get guest XML dump

2014-11-19 Thread Daniel Helgenberger

Hello,

after working with Foreman for a while come to love the yaml dump 
feature for hosts as it proved invaluable for debugging and setups [1].

After some questions on the list here if for instance libgfapi is being 
used I think such a feature also might prove useful in oVirt.
Right now, I log into the host running the vm and to this with virsh 
dumpxml.
I imagine something like - right click on a guest and choose 'XML 
dump'; or a XML tap in the VM edit window.

If somebody else thinks this is useful too, I will open a RFE.

Cheers,

 Subject: [ovirt-users] Power Management - but no LO?

 Hello,

 I am toying an idea involving using oVirt's PM capabilities (esp. the
 cluster power_saving policy) in conjuration with some consumer grate
 hosts for raw compute applications.

 Now, these hosts do not have any lights out or BMC capabilities.
 However, they could be started with WOL packets.

 Is there a way how this can be done in oVirt? Shutting down hosts with
 ssh and starting them with WOL?

 Yes, but you will have to write your own custom fencing script for that and 
 configure it as explain in
 http://www.ovirt.org/Custom_Fencing (look in the oVirt 3.5 section)
Is there any more documentation available? I found some older docs [1], 
are they still valid?
I struggle with how the mapping is done from parameters in the PM tab to 
functions in my fence agent, how it is passed to it and how it gets 
called in the end.
As I understood so far, oVirt needs to proxy PM/fencing operations and 
is using one host of the cluster for fencing; and PM the appropriate 
device. Also, I can use engine-config register the fence agent as well 
as to map some generic fields.


 If you need any details, please ask but mainly you should look on the scripts 
 in the fence-agents package (/usr/sbin/fence_*) and write something that 
 supports the common flags used by those scripts
Some basic design concepts I thought of so far:
I assume the virsh fence agent could work for me. It ssh's to the host. 
I would call shutdown in this case I think?
Further, while compiling the appropriate WOL packet seems trivial in 
python, I need to map an NIC MAC address witch I could get from a 
parameter in the PM setup. But in this case, any host could be used 
execute the script; preferring the engine in this case? Or is this a bad 
approach for some reason? (Assuming the NIC is part of ovirt management 
net).

I think I can manage to do this once I have figured out the basic stuff. 
Strangely, though I found posts by people who also tried to attempt a 
WOL fence agent this as not been accomplished it seems. Can you think of 
a reason? (I can think of shutdown, witch needs ssh to be done).

Thanks for any help on the issue.

[ovirt-users] Power Management - but no LO?

2014-11-18 Thread Daniel Helgenberger

Hello,

I am toying an idea involving using oVirt's PM capabilities (esp. the 
cluster power_saving policy) in conjuration with some consumer grate 
hosts for raw compute applications.

Now, these hosts do not have any lights out or BMC capabilities. 
However, they could be started with WOL packets.

Is there a way how this can be done in oVirt? Shutting down hosts with 
ssh and starting them with WOL?

Thanks!

Hello Joop,

thanks for raising the issue as it is one of the things I assumed are 
already implemented and working.

Sadly I cannot provide any answer ...

 work. Systems used:
 - hosts Centos7 or Fedora20 (so upto date qemu/libvirt/oVirt(3.5))
 - glusterfs-3.6.1
 - vdsm-4.16.0-524.gitbc618a4.el7.x86_64 (snapshot master 14-nov)
 - vdsm-4.16.7-1.gitdb83943.el7.x86_64 (official ovirt-3.5 vdsm, seems
 newer than master snapshot?? )

 Just adding the patch to vdsm-4.16.7-1.gitdb83943.el7.x86_64 doesn't
 work, vdsm doesn't start anymore due to an error in virt/vm.py.

 Q1: what is de exact status of libgf and oVirt.
 Q2: how do I test that patch?

Re: [ovirt-users] Latest ovirt-node release/installation

On 13.11.2014 20:58, Christopher Young wrote:
I sincerely hope that this is not answered elsewhere as I've done several
searches and have yet to find a solid answer. I have three (what I believe to
be) basic questions (with perhaps some subs there):

1) What is the latest oVirt-node release and where would one download it (I
appear to only see 3.4 -based releases of the ISO available)? It is 3.5-based
and/or is there an upgrade path? Which glusterfs release is currently
included
with oVirt-node?

I take the liberty to add Fabian to this thread.
Here is the link to the most current node release:

http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovirt35.20140912.el6.iso
see [1]

2) As I understand it, newer releases of oVirt-node allow you to do an
installation of the self-hosted engine at this time. Is that correct?
Be aware, this is not a stable release ATM but provides HE features.
This works quite cleverly by fetching an OVF offline engine install.

3) Is there any functionality that one would be losing out on by deploying
oVirt
via oVirt-node vs. using full-OS installation? Which is the more recommended?
Here I go along with Sven's notes for most of the part. The node project
is quite ambitious. You might have some troubles with special hardware.
Esp. SELinux is a real challenge, also EL7 with systemd. But if you want
(many) lightweight hosts witch standard hardware and an easy deployment
cycle, node is for you. Give it a try and see if it suits your needs and
share your experience...

Again, I apologize if these questions are covered somewhere, but I felt like
asking them in a direct fashion so as to clear up my own ignorance. I
appreciate any feedback and information that you could share.

Thanks,

Chris

Hey,

to be able to give Node a go on the oVirt 3.5 TestDay, we provide a
fresh build of Node including the 3.5rc2 package here:

http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovirt35.20140912.el6.iso

We did not see any SELinux denials, but if you experience any problems,
please try to install Node in permissive mode by appending
enfcoring=0
during the installation.

Imagine oVirt Node as something similar to EXi hypervisor; it is an imae

minimal) CentOS, RHEL, Fedora install.

 Is a ¨node¨ a end user machine that uses a virtual machine?
 Finally i want a Windows 7 virtualistion.
There is no problem with that and Windows is very well supported as 
guest OS.
For all of those, have a look on the excellent ovirt admin Guide [1]. 
This is still for oVirt 3.4 - but most of the stuff is true for 3.5 as well.

Hehe, just the same here.
I see this only on VM startup, though.

I thought this might be because the balloon driver needs the guest agent

 - Make sure Foreman is running at version X
 - Install RPMs in Foreman (see Bare-Metal Provisioning)

 I don't see why the current way we arrange the page is misleading.
Sorry if this is unclear. But:

For the Test button in Add external provider in Engine GUI to work, 
one *needs* do this on the Foreman host:
# yum install ruby193-rubygem-ovirt_provision_plugin

If this this assumption is true (it was for me reproducible) 
Foreman/oVirt communication will fail.
Therefore I am still convinced it is reasonable to put this as the first 
step before ever trying to add the provider in oVirt.*

The other things, like bare metal prov. and so on are optional.
Installing the oVirt - provider on the Foreman host is not.


 We have under Detailed Description 3 levels which have different
 prerequisites -
 Adding installed Foreman hosts as oVirt hosts - which just requires
 foreman setup,
To make this clear, this is not correct since the default foreman setup 
does not have the oVirt provider module installed. There are some use 
cases where Foreman is added because of oVirt, and some will have 
Foreman already runningin their infra. In this case, foreman-installer 
was already run.


* At least I was struggling with this requirement. Truth be told, 
Foreman was one point on a (very long) check list of mine; so I might 
not have paid proper attention to the details. OTOH the document 
suggested a strait forward approach with nice details and icons on how 
to do it oVirt. For instance, when I got to the section Bare Metal 
Provisioning I looked briefly over the requirements and decided to do 
this later on. Wrong here, since there is what I need to get it running 
in the first place!
The other issue, having two different (one obsolete) ForemanIntegration 
docs, is solved now.

 Bare-Metal Provisioning - which requires many things. starts with the
 ovirt plugin, discovery plugin, configuration of hostgroups
 computeresource medias and ends with setting the provisioning templates
 accordingly for node installation.

 and last - Future Plans: VM provisioning which still in declaration phase.



 next foreman build foreman-installer will include the
 --enable-foreman-plugin-ovirt-provision option which will make it
 easier. its already merged.
 This is great to know!


 Second, about the openjdk issue, I don't think it worth to mention. I'll
 add to the Current Status section that the integration is supported
 over rhel6.6 and above.
 This will do here.

Hi,

We had a consulting partner who did the same for our company. This is his 
procedure and worked great:

How to migrate ovirt management engine
Packages
Ensure you have the same packages  versions installed on the destination 
hostas on the source, using 'rpm -qa | grep ovirt'. Make sure versions are 
100%identical.
Default setup

Run 'engine-setup' on the destination host after installing the packages. Use
the following configuration:
1.Backup existing configuration
2.On the source host, do:
You might want your consultant take a look on [1]...
Steps a-3d:
engine-backup mode=backup --file=~/ovirt-engine-source --log=backup.log

a.service ovirt-engine stop
b.service ovirt-engine-dwhd stop
c.mkdir ~/backup
d.tar -C /etc/pki/ovirt-engine -czpf ~/backup/ovirt-engine-pki.tar.gz .
e.tar -C /etc/ovirt-engine -czpf ~/backup/ovirt-engine-conf.tar.gz .
f.cd /usr/share/ovirt-engine/dbscripts
g../backup.sh
h.mv engine_*.sql ~/backup/engine.sql
3.You may also want to backup dwh  reports:
a.cd /usr/share/ovirt-engine/bin/
b../engine-backup.sh --mode=backup --scope=db --db-user=engine 
--db-password=XXX --file=/usr/tmp/rhevm-backups/engine-backup 
--log=/tmp/engine-backup.log
c../engine-backup.sh --mode=backup --scope=dwhdb --db-user=engine 
--db-password=XXX --file=/usr/tmp/rhevm-backups/dwh-backup 
--log=/tmp/engine-backup.log
d../engine-backup.sh --mode=backup --scope=reportsdb --db-user=engine 
--db-password=XXX --file=/usr/tmp/rhevm-backups/reports-backup 
--log=/tmp/engine-backup.log
4.Download these backup files, and copy them to the destination host.
Restore configuration
1.On the destination host, do:
Again, steps a-h, basically
engine-setup
engine-cleanup
engine-backup mode=restore --file=~/ovirt-engine-source --log=backup.log

also, I would run a second
engine-setup
After that, you should be good to go..

Of course, depending on your previous engine setup this could be a little more 
complicated. Still, quite strait forward.
[1] http://www.ovirt.org/Ovirt-engine-backup
a.service ovirt-engine stop
b.service ovirt-engine-dwhd stop
c.cd backup
d.tar -C /etc/pki/ovirt-engine -xzpf ovirt-engine-pki.tar.gz
e. tar -C /etc/ovirt-engine -xzpf ovirt-engine-conf.tar.gz
f. tar -xvjf engine-backup
g. tar -xvjf dwh-backup
h. tar -xvjf reports-backup
 
Restore Database
1.On the destination host do:
a.su - postgres -c psql -d template1 -c 'drop database engine;'
b. su - postgres -c psql -d template1 -c 'create database engine owner 
engine;'
c. su - postgres
d. psql
e.  \c engine
f.  \i /path/to/backup/engine.sql
NOTE: in case you have issues logging in to the database, add the following
  line to the pg_hba.conf file:

   hostallengine127.0.0.1/32http://127.0.0.1/32trust

2.Fix engine password:
a.su - postgres
b. psql
c.alter user engine with password 'XXX';
Change ovirt hostname
On the destination host, run:

 /usr/share/ovirt-engine/setup/bin/ovirt-engine-rename








NB:
Restoring the dwh/reports database is similar to steps 5-7, but omitted from
this document due to problems starting the reporting service.

 Or are you only doing backups, no restore? :-P

gladly I just had to test disaster recovery and not actually
 perform it (yet) :D

To be honest: I never  have restored ovirt-engine with running vdsm
hosts connected to it, sounds like a lot of fun, I see if I can
grab some time and try this out myself :)

By your description I guess you have nfs/iso domain on your engine host?
why don't you just seperate it, so no need for remounts
if your engine is destroyed.

 http://www.ovirt.org/Features/AdvancedForemanIntegration
With foreman 1.6 (at least) there is no need to enable the nightly 
builds any more as rb-ovirt is resolved by yum.

Lastly, I think you need to enable foreman_discovery with the foreman 
installer to work and download images:

# foreman-installer --enable-foreman-plugin-discovery 
--foreman-plugin-discovery-install-images=true

You have that already listed in the testing env setup; but this needs to 
be put in context with installing foreman-ovirt on the foreman host.

 Well yes there is local storage in production at various sites.
 For real HA you inevitable need a shared storage solution.
An example and 'real' use case to Svens answer:
The term 'local' might indeed a bit misleading. The posix file system 
option basically lets you use anything posix compliant. For instance I 
am using a cluster file system called StorNext in our company - witch is 
very well suited for use with oVirt. Without POSIX, I could not have 
used it.


 You could try to utilize local disks by using gluster ceph
 or any other software defined storage system.

 Gluster is the most integrated withing ovirt, but here are some
 caveats:

 It's not encouraged to run vms on the hosts which are part of the
 gluster cluster (but it works, at least this is what you can read on
 this very ML).

 It's not supported to run hosted-engine on top of gluster, at least
 not without a replica count of at least 3.
Posix enables usage of GlusterFuseFS. However, it might be the case the 
replica 3 is only needed when using FuseFS [1], independent from the 
fact of using Gluster and Compute on the same host.

 Even the short list of items mentions so far are big features we would need
 to do justice with.
 this means probably a slightly longer cycle than the 6 months we currently
 do.

 We're not so good in keeping up with deadlines - our recent 3.5 version
 slipped for 2.5 months past the original plan. With longer cycles, this
 is even harder to control.

 Can we instead break the heavier features to smaller phases, that are
 easier to maintain, and deliver the complete feature in 3.7?

 Hey,

 yep, I think this is a good idea to get control over the big features.

 - fabian
Me too, for that matter. I think json rpc was a major thing to do witch 
went well; but maybe drew resources from other features and testing.

But maybe new features do not need to be scrubbed but implemented later 
on for upgrades? For instance, some software vendors allow new features 
for X.0 releases only for new installations. Only after they are 
confirmed working regression - free a X.1 version is released witch 
enables upgrades from X-1 (existing customers).

Bottom line, I hope for planned 3.6 features like SR-IOV and pci 
passthrough/vfio will not be postponed :)


 with many of the features requiring way newer versions of some of the
 components, I think we should plan for 3.6 cluster to require an .el7
 host
 (expecting even 7.1 to be out before we release oVirt 3.6).

 so i want us to plan for:
 - oVirt 3.6 supports .el6 and .el7 hosts in 3.5 cluster (and for fedora
- fc20?)
 - oVirt 3.6 supports .el7 in 3.6 cluster (and for fedora - fc21?)

Re: [ovirt-users] Protecting the storage of the self hosted engine

 Hi, I am new on oirt.
Hello and welcome!


 I want to know the best way to protect the storage of the hosted-engine?
IHMO reliable hardware and contingency plans.


 In Ovirt3.5, only NFS and iSCSI are supported for the engine VM, so this means
 that the NFS server or the iSCSI volume become the weak link.
First we need to define 'weak link'. IMOH this can be Network and / or 
storage hardware like controllers and spindles (SSDs). As the later 
tends to be reliable I think your mean indeed the data link layer as 
'weak link'?

Gluster can be the same weak link for instance, as it needs a network 
layer. If you use iSCSI together with some storage appliance maybe with 
redundant controllers, this setup is quite reliable and engine storage 
is protected if you use iSCSI Multipath (and the paths are indeed 
separate hardware switches).

You could call NFS a weak link; but even there are quite reliable setups 
available witch support fail over, replicated storage and IPMP.


 I've read two articles, one using GlsuterFS+NFS and CTDB for High availability
 of the engine storage,: oVirt 3.4, Glusterized
I have to warn you at this point. This setup seems quite tempting; even 
using localhost addresses with gluster's build in NFS. This was tried 
before (myself included) but it is far from stable.

You would at least need repica 3 gluster volumes to avoid split brains. 
These seem to happen quite often. I include Martin here, we talked about 
this at the ovirt workshop in Düsseldorf; maybe he can provide a better 
explanation.

AFAIK gluster will be supported as engine storage in the future; but 
this is not the case right now. Of course, you are welcome to try!

That said, and because you are new to ovirt, the main thing you need to 
protect is not the engine storage, but your production data domains.

The VMs will run fine and continue to run with the engine down or not 
available. In case of a real disaster, you will be able to import these 
storage domains along with their VMs to a new engine.

For me, I tend to have my engine backed up using engine-backup [1] and 
put the result to a different storage. From that data you can recreate 
the whole engine.

 Hi,

 currently ksmd is a single process
 and is thus bound to one core.

 This leads to some scaling problems such as:

 If you got a lot of vms on one host with huge amounts
 of ram you can observe that the cpu usage by ksmd
 goes easily to 100%.
I wonder what would be the benefit here... I think spending CPU cycles 
on something like memory compression is not what (most) users would do. 
Already I think this is an annoyance; maybe thats why the process is 
niced to +5. A multi process daemon would require careful confining 
(with cgroups).
To my understanding the for KSM to really work well is to have many 
(idle / high mem) guests which are quite similar?


 I wonder if ksmd could not be split up
 in child/worker threads, thus enabling higher density
 of vms on one host.

 It's likely going to be trickier than you imagine with the added
 locking that would be required to synchronize the ksmd threads.
Actually I was refraining to answer Svens question since I lack some 
knowledge here. But I guessed synchronization was the reason for the 
single threadted design.
Some serous work needs to be done on KSM do achieve this goal. I was 
thinking about some map/reduce aglo to do that... OTOH mangeling with 
mem pages of guests very requires special care.


 or can this just be tweaked by altering values in
 /etc/ksmtuned.conf ?

 I don't think it can.

 What do you think?

 Interesting idea.

 maybe a stupid one. Just want to make sure that nothing goes wrong. We
 plan to make a rolling upgrade of our landscape going to 3.5.1 in december.
 So we always need some hypervisor nodes up and running during the
 process.
This went fairly well with me. I did not loose a single machine and the 
process was transparent for them (I even had a script running lots of 
queries against a web server in one vm).

 Looking at older posts I assume that upgrading the engine should be
 sufficient, while hypervisor nodes with vdsm 4.14.17 (from 3.4 repos) and
 the active VMs keep on running. The start of the engine after the upgrade
 should catch up and resync all states.
The Engine and VDSM are fully backward compatible to each other [1]. So 
you should not see any problems there; only missing some features maybe.

 Afterwards I clean hypervisor hosts one by one and clean/reinstall it into
 the cluster?
This what I have done; remember you need to add the 3.5 repos otherwise 
VDSM will be (re)installed from the latest 3.4 repos and not upgraded to 
the '3.5' version. Also, this process went like a charm without any 
issues (let alone loosing guest)

 Thanks in advance.
Please keep in mind, upgrading your datacenter(s) to 3.5 might lead to 
some issues, some of them already fixed for 3.5.1 (I had some more 
severe ones). I would be careful with this setting in a production env. 
Also, some featues are available on cluster versions only; not requiring 
the more invasive datacenter upgrade [2].

 There are still 193 bugs [2] targeted to 3.5.1.
 Excluding node and documentation bugs we still have 164 bugs [3] targeted to 
 3.5.1.

 Maintainers / Assignee:
 - Please add the bugs to the tracker if you think that 3.5.1 should not be 
 released without them fixed.
 - Please update the target to 3.5.2 or later for bugs that won't be in 3.5.1:
it will ease gathering the blocking bugs for next releases.

 Hi,

 We are migrating our ifrastructure from kvm+libvirt hypervisors to ovirt.

 Everything is working fine but we're noticing that all the qemu-kvm
 processes in the hypervisors take a lot of CPU.
Without further details of the workload this is hard tell. One Reason I 
can think of might be KSM [1]. Is it enabled on your cluster(s)? What is 
your mem over-commitment setting?

Note, IIRC the KSM policy is currently hard coded; it will start at 80% 
host mem usage.

[1] http://www.ovirt.org/Sla/host-mom-policy

 The typical example is an idle machine, running top from the machine
 itself it reports cpu use percentages below 10% and loads (with 2
 processors) of 0.0x. The process running that machine in the hypervisor
 rports cpu uses in the order of the 80-100%.

 Should the values look like this? Why are the idle machines eating up so
 much CPU time?

 Thank you.
 Xavier

 Hi, thank you for the answer.

 I've been trying to work out some pattern and realized that the VMs
 using that much cpu all are Redhat 5.x, the Readhat 6.x doesn't exhibit
 this kind of high cpu use. (we run only redhat/centos 5.x/6.x on the
 cluster)
What OS are the hosts running? In case of EL6, make sure you have
tuned-0.2.19-13.el6.noarch installed [1].

To further investigate please post Engine, VDSM, libvirt and kernel
versions from the hosts.

[1] https://access.redhat.com/solutions/358033

 I'll take a look to the KSM config.

 Cheers,

 Xavier

 Actually, this seems to be it. But I'm already at a newer kernel:
 https://bugzilla.redhat.com/show_bug.cgi?id=705082
Well, I do not have such hardware so I never run into the issue. You 
could disable HT as I suspect your physical cores are less then 64?

Your workload might differ but my VMs usually do not benefit from 
'threaded' cores and I want HT disabled anyway. Also, you can check 
cluster settings and disable 'count threads as cores' if enabled. But I 
think this might not make any difference.
