Hi Nicolás,

Removing the default cluster should be ok, since the templates don't
bind VMs to a DC/Cluster--you should be able to specify the DC/Cluster
when creating a VM.

Hi Greg,

I'll elaborate a bit further on the issue. I'm attaching a screenshot of 
the 'Templates' tab on the webadmin pane - As you can see, all of them 
have a Data Center and a Cluster assigned (columns 4 and 5) but the 
Blank template (because we deleted the default DC). Even if this 
template has the 'Everyone' permission, as we're granting permissions to 
our users on the Data Center, they are not able to see the Blank 
template in the list when deploying new machines in the userportal view, 
so currently they necessarily need to choose a template from the list 
which is not Blank, and that's an issue to some of them.


That's why I was wondering if there's a manual way to assign the DC and 
Cluster to the Blank template, even modifying it directly in the DB, so 
the users see it in the userportal.


Any hint is very appreciated.

So I found some additional logs.. and from what I understand it’s trying to

configs in there..

So.. I manually edited the /etc/sysconfig/network-scripts and setup the device 
& bridge as expected.. but vdsm didn’t like it..  it was still trying to delete 
the ovirtmgmt device.

What I ended up doing in the end is defining the network in virsh (creating 
myself an account via saslpasswd2 -a libvirt USERNAME) then creating the 
ovirtmgmt bridge
# cat vdsm-ovirtmgmt.xml

  vdsm-ovirtmgmt
  
  


#virsh net-define vdsm-ovirtmgmt.xml
#virsh net-start vdsm-ovirtmgmt

Something still wasn’t right here.. so I ended up rebooting the host…  and then 
it was working.. I’m still not entirely sure what I did to fix it.. but it’s 
working now…

I’ll continue on the journey and keep this thread updated incase anyone else 
runs into the same issues!

Cheers

Hi Michael,



Thanks for this information - it's great, the guide should be updated on the 
ovirt webpage to reflect the information you've provided below.



Just to hopefully help someone else out in the future - we had only 1 vNIC 
defined in the UCS Service Profile, this caused problems when we enabled 
dynamic vnic's on that host.



The resolution was leave the initial interface as it is.. and as a management 
interface and setup another interface for the dynamic vnics. Ensure that your 
"vNIC/vHBA Placement" doesn't change either!



[cid:image001.png@01D16A64.FCDB9D60]



So in this case eth0 = ovirtmgmt bridge, and ovirt device is the vNICs.

When the system reboots after this change I’ve lost my bridge and vdsmd failed 
to start.



I manually setup the first interface again so I can talk to it again and I’ve 
even setup the bridge but I can’t get it working again? Below is what I see 
in the logs. I’ve even tried a re-installation(ovirt maint/reinstall) but no 
joy..



I’ve managed to get this working on 1 host.. but no idea what I did that was 
different!?.. If I remove the vNIC ovirt it starts working as expected - where 
can I find out some more information on what vdsm is doing?

HI David)



If everything configured properly on your UCS side and you have a working Port 
Profile id/name your next steps should be:



1) Run for example:

engine-config -s 
CustomDeviceProperties="{type=interface;prop={ifacemacspoof=^(true|false)$;queues=[1-9][0-9]*;vmfex=^[a-zA-Z0-9_.-]{2,32}$;SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
 *)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}}" --cver=3.5



- Restart your ovirt-engine service

- with --cver=3.5 you can specify your cluster version level. ^^

- If you don't want that it will overwrite your current attributes, you have to 
send them all as well(like on my example above). ^^



2) Install vdsm-hook-vmfex-dev on your nodes



3) In ovirt engine you can verify that host have the hooks installed under  
'Hosts' main tab - > 'Host Hooks' sub tab You should see there: a) 
before_device_migrate_destination b) before_device_create c) before_nic_hotplug

4) Create new network and edit the vNIC profile. Cho

That fixed it!

FYI: I actually obtained ovirt-hosted-engine-setup 1.3.3.3 by using
the 2016-02-17 ovirt node iso,
ovirt-node-iso-3.6-0.999.201602171021.el7.centos.iso, which contains
it.

Hi,

  I'm trying to set up VDSM-Fake
(git://gerrit.ovirt.org/ovirt-vdsmfake.git) for some tests, however,
I'm a bit confused about how does it actually work. As the
instructions say, I was able to build the project with Maven (however,
the org.ovirt.vdsm-jsonrpc-java dependency version had to be changed
to 1.1.5 instead of 1.1.2-SNAPSHOT in pom.xml as this latter is no
longer provided at the repository).

  Once built, I run mvn jetty:run and the server started correctly:


2016-02-02 11:01:51.957:INFO::jetty-6.1.26  [1]
2016-02-02 11:01:52.804:INFO::No  [2] Transaction manager found - if

SelectChannelConnector@0.0.0.0:54321

[INFO] Started Jetty Server
[INFO] Starting scanner at interval of 10 seconds.

  I could indeed verify it's listening on the VDSM port:


[root@host ovirt-vdsmfake]# netstat -atpn | grep 54321
tcp6   0  0
:::54321
:::*LISTEN
44870/java

  So the next step is to add a fake host via REST. I used scripts
provided here [4] and I successfully added the host, however, it
starts installing all the VDSM packages as it were a normal host and
therefore it tries to start vdsmd as well, which throws an error as
the Jetty Server is already listening on the 54321 port. I shut down
the Jetty Server and allowed oVirt Manager to install all the packages
properly, then stopped vdsmd and started the Jetty Server, but
expectedly oVirt Engine fails with message "Host xxx is non
responsive", so what I actually got is a real VDSM host and not a fake
one.

  FWIW, the fake VDSM runs on a different host, ports are reacheable
from the oVirt engine, proper /etc/hosts has been added to the engine
to reach the host, and no further customization of web.xml has been
done.

  I feel like I'm missing something here. Could someone shed some light
on what's wrong?

  Thanks.

  Nicolás



@Nicolas I would recommend you to use the top of my gerrit patches to 
run vdsmake:


  git clone git://gerrit.ovirt.org/ovirt-vdsmfake 


  cd ovirt-vdsmfake
  git fetch git://gerrit.ovirt.org/ovirt-vdsmfake 
 refs/changes/70/53570/2 && 
git checkout FETCH_HEAD


then follow the instructions in the README of the checked out 
repository [3].


Hope that helps.

I could finally make fakevdsm work with your changes. Maybe I'm missing 
something but this works if the engine and the fake host are run on the 
same server - when I tried to run the fake host on a different host I 
wasn't seeing any responses from the host (the firewall was vanilla 
clean). In any case, I'm ok with both running on the same machine.


Will this be merged into master?

[ovirt-users] How to add RAM to Hosted Engine

[DiOrio, Max]

Hi There...new oVirt user.  After a bit of a learning curve, I have things set 
up pretty well.  The web console in the hosted engine is running slow, and it's 
spiking memory to 98% frequently, but I only have 4096MB of RAM allocated.  
Currently running oVirt 3.6.

>From the web interface, it doesn't seem possible to add memory to the hosted 
>engine VM.  I can add it via the Edit menu, but then it complains that "This 
>VM is not managed by the engine".

I see that some people have said to edit /etc/ovirt-hosted-engine-ha/vm.conf  
but this file does not exist.  Then I saw someone say that the file is now 
located in /var/run/ovirt-hosted-engine-ha/vm.conf  I do see this here, but I 
can't update the file.  Each time I go to update it, it reverts back to the 
previous config.

I shut down the VM then tried to edit it, same thing.  I put the system in 
global maintenance mode, shut down the vm, then tried to edit it, same thing.

[ovirt-users] Understanding direct lun connection: iscsi pass through disks

[Arman Khalatyan]

Hi, I am trying to combine performance and virtualisation with direct iscsi
disks .
Assuming we have vm with /dev/vda for OS two data disks from
iscsi01:/dev/sda and iscsi02:/dev/sdb direct lun disks configured over
ovirt interface.
The iscsi disks are used as zfs mirror inside the vm.
When one of the iscsi disks is not available then the whole host goes into
pause state.
Are there way to force ovirt do not freeze vm if direct lun is away?
Thanks,
Arman

in general - as many sockets as the number of cores you have available, minus a 
couple for the host OS(one or two should be ok)
you can run more, but then they will compete for the core and performance would 
decrease. But if those VMs are not CPU intensive it may very well be ok (you 
just need to disable the default cluster policy which limits the size to number 
of hosts’s cores)

[ovirt-users] Understand CPU Socket Cores and VCPU

[Taste-Of-IT]

Hello,
i have a general Question about Hardware CPU, Socket, Cores and the 
VCPU, Cores per VSocket and VScoket for virtual Machines. Example i have 
a single CPU with 4 Cores and 8 Threads. As far as i understand i should 
configure the virtual machines with that number of socket as the host 
has. So in this example with max 1 Socket. How is the possibility in 
VCPUs and VCores? What is the limit in this example? Can i only run max 
4 VMs?

Hi,

I'm trying to determine the correct "bad_img" uuid in my case.

The VM has two snapshots:

* The "Active VM" snapshot which has a disk that has an actual size
that's 5GB larger than the virtual size. It has a creation date that
matches the timestamp at which I created the second snapshot. The "disk
snapshot id" for this snapshot ends with dc39.

* A "before jessie upgrade" snapshot that has status "illegal". It has
an actual size that's 2GB larger than the virtual size. The creation
date matches the date the VM was initialy created. The disk snapshot id
ends with 6249.

 From the above I conclude that the disk with id that ends with 6249 is
the "bad" img I need to specify.


Similar to what I wrote to Marcelo above in the thread, I'd recommend
running the "VM disk info gathering tool" attached to [1].  It's the
best way to ensure the merge was completed and determine which image is
the "bad" one that is no longer in use by any volume chains.


I've ran the disk info gathering tool and this outputs (for the affected
VM):

VM lena
Disk b2390535-744f-4c02-bdc8-5a897226554b
(sd:a7ba2db3-517c-408a-8b27-ea45989d6416)
Volumes:
24d78600-22f4-44f7-987b-fbd866736249

The id of the volume is the ID of the snapshot that is marked "illegal".
So the "bad" image would be the dc39 one, which according to the UI is
in use by the "Active VM" snapshot. Can this make sense?


It looks accurate.  Live merges are "backwards" merges, so the merge 
would have pushed data from the volume associated with "Active VM" 
into the volume associated with the snapshot you're trying to remove.


Upon completion, we "pivot" so that the VM uses that older volume, and 
we update the engine database to reflect this (basically we 
re-associate that older volume with, in your case, "Active VM").


In your case, it seems the pivot operation was done, but the database 
wasn't updated to reflect it.  Given snapshot/image associations e.g.:


 VM Name  Snapshot Name  Volume
 ---  -  --
 My-VMActive VM  123-abc
 My-VMMy-Snapshot789-def

My-VM in your case is actually running on volume 789-def.  If you run 
the db fixup script and supply ("My-VM", "My-Snapshot", "123-abc") 
(note the volume is the newer, "bad" one), then it will switch the 
volume association for you and remove the invalid entries.


Of course, I'd shut down the VM, and back up the db beforehand.

I'm not terribly familiar with how vdsm handles block storage, but I'd 
image you could then e.g. `lvchange -an` the bad volume's LV, start 
the VM, and verify that the data is current without having the 
to-be-removed volume active, just to make sure everything lines up 
before running the vdsClient verb to remove the volume.


vdsm will reactivate the lv when starting the vm so this check will
not work.  The vm-disk-info.py script is using libvirt to check which
volumes the VM actually has open so if the 'bad' volume is not listed,
then it is not being used and is safe to remove.




Both the "Active VM" and the defective snapshot have an actual size
that's bigger than the virtual size of the disk. When I remove the bad
disk image/snapshot, will the actual size of the "Active VM" snapshot
return to the virtual size of the disk? What's currently stored in the
"Active VM" snapshot?


"Active VM" should now be unused; it previously (pre-merge) was the 
data written since the snapshot was taken.  Normally the larger actual 
size might be from qcow format overhead.  If your listing above is 
complete (ie one volume for the vm), then I'm not sure why the base 
volume would have a larger actual size than virtual size.


Adam, Nir--any thoughts on this?


There is a bug which has caused inflation of the snapshot volumes when
performing a live merge.  We are submitting fixes for 3.5, 3.6, and
master right at this moment.




Would cloning the VM (and removing the original VM afterwards) work as
an alternate way to clean this up? Or will the clone operation also
clone the snapshots?


It would try to clone everything in the engine db, so no luck there.

Rik


If indeed the "bad" image (whichever one it is) is no longer in use,
then it's possible the image wasn't successfully removed from storage.
There are 2 ways to fix this:

  a) Run the db fixup script to remove the records for the merged image,
 and run the vdsm command by hand to remove it from storage.
  b) Adjust the db records so a merge retry would start at the right
 place, and re-run live merge.

Given that your merge retries were failing, option a) seems most likely
to succeed.  The db fixup script is attached to [1]; as parameters you
would need to provide the vm name, snapshot name, and the id of the
unused image as verified by the disk info tool.

To remove the stale LV, the vdsm deleteVolume verb would then be run
from `vdsClient` -- but note that this must be run _on the SPM host_.
It will not only perform lvremove, but also do housekeeping on other
storage metadata to keep everything consistent.  For this verb I believe
you'll need to supply not only the unused image id, but also the pool,
domain, and image group ids from your database queries.

I hope that helps.

If you're already managing the gluster nodes in another cluster, there's 
no need to add it again. I'm not sure I understand the setup. You need 
to enable gluster services in the second cluster only if this is going 
to have gluster volumes running on it. To use a gluster volume (running 
on another cluster), there's no need to enable gluster service.

Hi Moti,

Thanks a lot. Do you think we lost functionalities? like server migration?
The other way should be creating a new cluster, configure the old 
hosts on this new cluster. Is possible to share the same GlusterFS 
storage between 2 clusters? Is possible to migrate servers and disks 
between the 2 clusters?

José

Hi Jose,

The correct way to do it is by:
1. Putting all hosts in maintenance mode
2. Changing the cluster cpu type to the desired one
3. Install the new host
4. Activate the hosts
5. Re-run the vms

Re: [ovirt-users] "bridge port" error when setting up hosted-engine on 2nd oVirt 3.6.2 node

[Simone Tiraboschi]

Thanks Mike,
could you please retry with ovirt-hosted-engine-setup 1.3.3.3 ?
http://resources.ovirt.org/pub/ovirt-3.6-pre/rpm/el7/noarch/ovirt-hosted-engine-setup-1.3.3.3-1.el7.centos.noarch.rpm
It should address also that.

thanks,
Simone

Yes, I am getting the answer files from node 1 (death-star). I've attached it.

That variable does not exist in it.

Re: [ovirt-users] Gluster 3.7.8 from ovirt-3.6-glusterfs-epel breaks vdsm ?

[Sahina Bose]

[+gluster-users]

Any known compat issues with gluster 3.7.8-1.el7 client packages and 
glusterfs 3.7.6-1.el7 server?



On 02/17/2016 04:33 PM, Matteo wrote:

Hi,

today I update one node os, in the updates gluster client
packages where upgraded from 3.7.6-1.el7, centos-ovirt36 repository
to 3.7.8-1.el7, ovirt-3.6-glusterfs-epel and after reboot
the node was marked not operational.

looking into the logs, vdsm was failing to get gluster volume information.

the command (ovirt-storage is the gluster storage where the hosted engine is 
kept)

gluster --mode=script volume info --remote-host=gluster1 ovirt-storage --xml

was failing, returning error 2 (and no output)

doing yum downgrade on gluster client packages (back to 3.7.6-1.el7, 
centos-ovirt36) fixed everything.

Data nodes are running glusterfs 3.7.6-1.el7.

The funny thing is that from the ovirt I was able to manually mount the 
glusterfs shares,
only the volume info command was failing, thus breaking vdsm.

Any hint?

Matteo

What does the mount log on the hypervisor say? Could you attach that?



As a workaround I've executed "*yum*downgrade glusterfs*" and after 
doing this ovirt started to work again...but as a collateral effect 
now I can't migrate my vm's anymore.  On the vdsm logs I can see the

Re: [ovirt-users] question mark in oVirt - "cannot acquire state change lock"

[p...@email.cz]

Hello,
some requested outputs

Vdsm generate a huge count of records in time, so I'm not shure if 
"hang" time is still included .

Problems occured 17-feb-2016 17:00-18:00 when VM shutdown was requested.
But some performance problems occured a day before ( I'm not shure about 
application problem = JAVA = running EBS )


In mail before  I attached pointers to bugs with any workaround

killall -9 libvirtd
rm /var/run/libvirtd.pid
/etc/init.d/libvirt-bin restart

which would solve current situation.
Is this  workaround safe enought?? Will stay VMs running ???

THX for any help, because I can't reboot hypervizor due huge DB traffic 
and no VM migration possibility via oVirt engine. ( mem synchro 
overloaded ?? )

[ovirt-users] Hosted engine storage "locked"

[Ollie Armstrong]

Hi,

I've updated from 3.6.1 to 3.6.2 and was hoping that the issue with
the hosted engine storage on FC not being imported would be solved.
It managed to start the import but now my storage has been stuck in
"Locked" for weeks.  None of the options in the web UI are available
except right click "Destroy".

Is there any way to restart the import process so maybe I can keep an
eye on the logs and find the issue?

Cheers,
Ollie

[ovirt-users] oVirt 3.6.2 issue when updating to gluster 3.7.8

[Luiz Claudio Prazeres Goncalves]

Hi, I realised that gluster 3.7.8 was released for GA. So I updated
manually using "yum -y install glusterfs*" gluster get's updated normally,
but  unfortunately things stopped to work completely.
ovirt_hosted_engine_ha was not able to connect to my gluster storage domain
(as you can see below). I'm not using ovirt + gluster in hyperconverged
way. I have 3 external gluster hosts.

As a workaround I've executed "*yum* downgrade glusterfs*" and after doing
this ovirt started to work again...but as a collateral effect now I can't
migrate my vm's anymore.  On the vdsm logs I can see the following errors
when trying to manually migrate a any VM Anyone knows how to fix it?

[ovirt-users] Gluster 3.7.8 from ovirt-3.6-glusterfs-epel breaks vdsm ?

[Matteo]

Hi,

today I update one node os, in the updates gluster client
packages where upgraded from 3.7.6-1.el7, centos-ovirt36 repository
to 3.7.8-1.el7, ovirt-3.6-glusterfs-epel and after reboot
the node was marked not operational.

looking into the logs, vdsm was failing to get gluster volume information.

the command (ovirt-storage is the gluster storage where the hosted engine is 
kept)

gluster --mode=script volume info --remote-host=gluster1 ovirt-storage --xml

was failing, returning error 2 (and no output)

doing yum downgrade on gluster client packages (back to 3.7.6-1.el7, 
centos-ovirt36) fixed everything.

Data nodes are running glusterfs 3.7.6-1.el7.

The funny thing is that from the ovirt I was able to manually mount the 
glusterfs shares,
only the volume info command was failing, thus breaking vdsm.

Any hint?

regards,
Matteo

I've ran the disk info gathering tool and this outputs (for the affected
VM):

VM lena
Disk b2390535-744f-4c02-bdc8-5a897226554b
(sd:a7ba2db3-517c-408a-8b27-ea45989d6416)
Volumes:
24d78600-22f4-44f7-987b-fbd866736249

The id of the volume is the ID of the snapshot that is marked "illegal".
So the "bad" image would be the dc39 one, which according to the UI is
in use by the "Active VM" snapshot. Can this make sense?

Both the "Active VM" and the defective snapshot have an actual size
that's bigger than the virtual size of the disk. When I remove the bad
disk image/snapshot, will the actual size of the "Active VM" snapshot
return to the virtual size of the disk? What's currently stored in the
"Active VM" snapshot?

Would cloning the VM (and removing the original VM afterwards) work as
an alternate way to clean this up? Or will the clone operation also
clone the snapshots?

Regards,

Rik

 a status of "illegal". Is it OK to (try to) remove this
 snapshot? Will
 this impact the running VM and/or disk image?

I forgot to attach the screenshot. Here it goes.

Hi,

We're using oVirt 3.6.2.6, and we're having some events not being
cleared from the Tasks tab. I cannot confirm this is only related to
creating VM pools, but any created VM pool remains unfinished forever
in the Tasks tab. As you may see in the screenshot, there are events
that were started in January and are still in the list. Concretely,
the unfinished step is always "Finalizing".

Has this been reported on Bugzilla?

Is there a way to clear them out even manually?

Thanks.

Are you using an answerfile?
Can you please check the value of OVEHOSTED_NETWORK/bridgeIf ?
