[ovirt-users] Re: oVirt and Windows NFS

[Pavel Gashev]

Ron,

It works for preallocated disks only. So if you have a Microsoft powered 
storage, it's better to use Microsoft iSCSI.

Hi Everyone - Greetings from Detroit Michigan!

Has anyone had any luck with using oVirt to connect to a Windows Server 
running an NFS service?

I've made several attempts so far and am having problems getting the two to 
work together.  I was hoping someone had some hints (besides the obvious "use 
Linux" bit).

Thanks!

[ovirt-users] Re: VM hangs after live migration

[Pavel Gashev]

 I believe there is an issue with online migration from qemu 2.6.0. I hit it 
too. Online migration from latest 2.6.0 to latest 2.9.0 worked with no random 
VM hangs for me.

To solve this hangup, there was only power off.

Re: [ovirt-users] Q: VM disk speed penalty NFS vs Local data center storage

[Pavel Gashev]

Andrei,

You could try pNFS. It allows to access a data on a local storage directly 
bypassing NFS and even FS level.
Unfortunately, it requires SCSI Persistent Reservation feature so would not 
work all RAID controllers.

Hi,

Since oVirt doesn’t support more then 1 host in data center with local storage

I have to setup NFS server on node with VMs (on same node) access via NFS.
10 GB shared storage is in the future plans yet right now have only 2 nodes 
with local RAID on each.

Q: What is VM disk speed penalty (approx %)  NFS vs Local RAID in oVirt data 
center storage?
Currently I have 2 VMs running our accounting/inventory control system which 
are critical to storage performance limits.
2 other VMs have very low disk activity.

I don't know, but please remember there's both latency and throughput, both of 
which are somewhat affected. Throughput will benefit from jumbo frames, for 
example. Unfortunately it may affect latency a bit.
There was an interesting patch that if the NFS was local, bypassed the NFS[1]. 
It was never completed and merged.
Lastly, chapter 6 at hyper-converged guide (should be available in few hours) 
might be an interesting idea for you to consider - a single Gluster that can 
later expand.

Re: [ovirt-users] deprecating export domain?

[Pavel Gashev]

Shubham,

I hope you’re going to keep the Export feature at least as “Clone to another 
storage domain”. In the real life, the copy-in/copy-out is required for 
backups. Moving disks between Data SD and Backup SD is not a way to backup or 
restore. It’s often required to keep VM runnable during backing up, and it’s 
often required to keep a backup during restoring. Typical backup storage is not 
designed for running VMs directly. SSDs are not cheap enough for storing 
backups, and there are HDDs especially designed for storing cold data [1]. 
Thus, the disaster recovery scenario is a great feature, but it can’t be a 
recommended way to recover.

And I hope you are going to show VMs on backup storages in a separate list 
(“Backups” instead of “Virtual Machines”).

[1] http://www.seagate.com/enterprise-storage/hard-disk-drives/archive-hdd/

I hope this helps.

Yes, I just gave an example case. If you want to use vms with a backup, then 
you can just copy that vm or disk into another domain and make it as backup 
domain as you do it in export domain.
In simple language, main aim of creating backup domain is just to use all the 
features available in export domain without creating a dedicated export domain.
Hope you understand now:)

Hi,
The backup storage domain is quite like export storage domain but with easy 
usability.
Since you can change any data domain into backup domain any time, you not need 
to create a dedicated
export storage domain for backup or disaster recovery purpose. Altough its 
working is same as export sd.
The process of backup can be as simple as this:
1) turn off all the vms in your storage domain
2) select backup flag to convert that into backup domain.
Once the domain is used for backup, you cannot make any changes to its vms, 
disk etc as mentioned by maor.
And yes, you can convert export sd to data domain using cli script but it is 
not required anymore.
If in future export storage domain get deprecated, you not need to be worry 
about that much since you can convert all your
export sd into data domain anytime and start using backup feature instead.

Shubham

Maor,

Could you please clarify, what would be the process of making backup of a 
running VM to an existing backup storage domain?

I’m asking because it looks like the process is going to be quite the same:
1. Clone VM from a snapshot
2. Move the cloned VM to a backup storage domain

An ability of choosing destination storage for cloned VMs would increase backup 
efficiency. On the other hand, an ability of exporting VM from a snapshot would 
increase the efficiency in the same way even without creating new entity.

Indeed, Backup SDs would increase efficiency of disaster recovery. But the same 
would be achieved by converting Export SDs to Data SDs using a small CLI 
utility.

That is a good question.
We recently introduced a new feature called "backup storage domain"
which you can mark the storage domain as backup storage domain.
That can guarantee that no VMs will run with disks/leases reside on
the storage domain.

non-runnable. It doesn’t look like a backing up. It looks like an archiving. 
But what if I need to keep my VMs running?

Subject: Re: [ovirt-users] deprecating export domain?

Hi,
The backup storage domain is quite like export storage domain but with easy 
usability.
Since you can change any data domain into backup domain any time, you not need 
to create a dedicated
export storage domain for backup or disaster recovery purpose. Altough its 
working is same as export sd.
The process of backup can be as simple as this:
1) turn off all the vms in your storage domain
2) select backup flag to convert that into backup domain.
Once the domain is used for backup, you cannot make any changes to its vms, 
disk etc as mentioned by maor.
And yes, you can convert export sd to data domain using cli script but it is 
not required anymore.
If in future export storage domain get deprecated, you not need to be worry 
about that much since you can convert all your
export sd into data domain anytime and start using backup feature instead.
Regards,
Shubham

Could you please clarify, what would be the process of making backup of a

I’m asking because it looks like the process is going to be quite the same:
1. Clone VM from a snapshot
2. Move the cloned VM to a backup storage domain

An ability of choosing destination storage for cloned VMs would increase backup 
efficiency. On the other hand, an ability of exporting VM from a snapshot would 
increase the efficiency in the same way even without creating new entity.

Indeed, Backup SDs would increase efficiency of disaster recovery. But the same 
would be achieved by converting Export SDs to Data SDs using a small CLI 
utility.

That is a good question.
We recently introduced a new feature called "backup storage domain"
which you can mark the storage domain as backup storage domain.
That can guarantee that no VMs will run with disks/leases reside on
the storage domain.
The feature should already exist in oVirt 4.2 (despite a bug that
should be handled with this patch https://gerrit.ovirt.org/#/c/81290/)
You can find more information on this here:
  
https://github.com/shubham0d/ovirt-site/blob/41dcb0f1791d90d1ae0ac43cd34a399cfedf54d8/source/develop/release-management/features/storage/backup-storage-domain.html.md

Basically the OVF that is being saved in the export domain should be
similar to the same one that is being saved in the OVF_STORE disk in
the storage domain.
If the user manages replication on that storage domain it can be
re-used for backup purposes by importing it to a setup.
Actually it is much more efficient to use a data storage domain than
to use the copy operation to/from the export storage domain.

Re: [ovirt-users] CBT question

[Pavel Gashev]

The dirty bitmap is already working well enough in QEMU 2.6. It can be used via 
LibVirt qemu-monitor-command. The only issue is that dirty bitmaps do not 
sustain VM restarts, snapshot creating/deleting, and VM live migration. 
However, this is not a big issue if you perform backups often than these 
operations. Since backups are in the qcow2 format, they can be placed on the 
Export storage, and restored directly from oVirt.

It would be relative simple to implement third-party backup solution, if disk 
locking mechanics was accessible via oVirt API. Implement this directly in 
oVirt would be even simpler as a Live Export feature, since dirty bitmaps work 
exactly like snapshots, and oVirt already has most of required logic.

Re: [ovirt-users] Good practices

[Pavel Gashev]

Fernando,

I agree that RAID is not required here by common sense. The only point to setup 
RAID is a lack of manageability of GlusterFS. So you just buy manageability for 
extra hardware cost and write performance in some scenarios. That is it.

 wrote:

That's something on the way RAID works, regardless what most 
'super-ultra' powerfull hardware controller you may have. RAID 5 or 6 
will never have the same write performance as a RAID 10 o 0 for example. 
Writeback caches can deal with bursts well but they have a limit 
therefore there will always be a penalty compared to what else you could 
have.

If you have a continuous stream of data (a big VM deployment or a large 
data copy) there will be a continuous write and that will likely fill up 
the cache making the disks underneath the bottleneck.
That's why on some other scenarios, like ZFS people have multiple groups 
of RAID 6 (called RAIDZ2) so it improves the write speeds for these type 
of scenarios.

In the scenario given in this thread with just 3 servers, each with a 
RAID 6 there will be a bare limit on the write performance specially for 
streammed data for most powerfull your hardware controller can do 
write-back.

Also I agree the 40Gb NICs may not be used fully and 10Gb can do the job 
well, but if they were available at the begining, why not use them.

Subject: [ovirt-users] Host stuck unresponsive after Network Outage

Hey Ovirt Users and Team,

I have a host that I am unable to recover post a network outage.  The host is 
stuck in unresponsive mode, even though the host is on the network, able to SSH 
and seems to be healthy.  I’ve tried several things to recover the host in 
Ovirt, but have had no success so far.  I’d like to reach out to the community 
before blowing away and rebuilding the host.

Environment: I have an Ovengine server with about 26 Datacenters, with 2 to 3 
hosts per Datacenter.  My Ovengine server is hosted centrally, with my hosts 
being bare-metal and distributed throughout my environment.Ovengine is 
version 4.0.6.

What I’ve tried: put into maintenance mode, rebooted the host.  Confirmed host 
was rebooted and tried to active, goes back to unresponsive.   Attempted a 
reinstall, which fails.

Checking from the host perspective, I can see the following problems:

[boxname~]# systemctl status vdsmd

Hi Phillip,

your hosted engine storage is on nfs, right? Did you test if you can
mount manually on each host?
Hi Luca,

Yes, both storage domains are on NFS (v3) and I am able to successfully mount

Re: [ovirt-users] Bizzare oVirt network problem

[Pavel Gashev]

Fernando,

The issue can be triggered by a packet with the same source MAC address as VM 
has. If it’s received by network equipment from some different port, your VM 
could stop receiving network traffic.

There are two options. Either there is a network topology issue, or there is 
another VM with the same MAC address. The last is possible if you have another 
oVirt installation (testing? staging?) in the same network segment.

- The Kernel used is 4.12 (elrepo) instead of the default 3.10
- The ovirtmgmt network is used also for the Virtual Machine showing this

Has anyone have any idea if it may have anything to do with oVirt (any filters)

Since the restart is not actually required in my case, what if I set

I have no plans to restart my VMs in this year.

Sorry for butting in, this has nothing to do with the subject but are you 
seriously _not_ going to the restart your VM's this year?

If so, then how are you handling patching/upgrading of them? Because if you 
aren't, you are going to have bigger problems than we can help you with:)

Just my two cents

And I don’t want to block online updating of VM parameters by the “next run

Re: [ovirt-users] Unable to add storage domains to Node Hosted Engine

I believe the deadlock described in the article is nearly impossible when VM

Anyway, there is a solution to avoid loopback NFS:

This article is from 2014.  Are you saying that this issue hasn't been
fixed in the intervening three years?

FWIW I'm running with Loopback NFS on my single-host Ovirt 4.0.6 system
and it's been running happily for a while now.  I would have happily
used a local filesystem, but the hosted-engine code wouldn't let me.
Setting up loopback NFS was easier than trying to learn GlusterFS and
figure out how to loopback Gluster.

On the other hand, my system does have 256GB of RAM, with only about 50%
being used, so that also might work in my favor.

Interesting idea!

The only issue I see if not having a way to tell if the file system was actually
unmounted. Does process termination guarantee that the file system was
unmounted?

You can double check that by deactivating underlying LV. It should not be busy.

As I understand it unmounts FS as soon as all inodes are closed. Since killing 
of process is closing all open inodes, you can be sure that file system is 
unmounted if there are no other processes. Of course this is a place for race 
conditions. For example, unmounting can be stuck some time if underlying 
storage is unresponsive. Multipath should drop all IOs with EIO. VDSM has to 
wait enough time after acquiring the lock before mounting masterfs.

Do you know if the behaviour is documented somewhere?

umount(8):

-l, --lazy
Lazy unmount.  Detach the filesystem from the filesystem hierarchy now, and 
cleanup all references to the filesystem as soon as it is not busy anymore.

Re: [ovirt-users] massive simultaneous vms migrations ?

[Pavel Gashev]

VDSM has the following config option:

# Maximum concurrent outgoing migrations
# max_outgoing_migrations = 2

On Tue, 2017-04-18 at 18:48 +0200, Nelson Lameiras wrote:
hello,

When putting a host on "maintenance mode", all vms start migrating to other 
hosts.

We have some hosts that have 60 vms. So this will create a 60 vms migrating 
simultaneously.
Some vms are under so much heavy loads that migration fails often (our guess is 
that massive simultaneous migrations does not help migration convergence) - 
even with "suspend workload if needed" migraton policy.

- Does oVirt really launches 60 simultaneous migrations or is there a queuing 
system ?
- If there is a queuing system, is there a way to configure a maximum number of 
simultaneous migrations ?

I did see a "migration bandwidth limit", but this is quite what we are looking 
for.

my setup:
ovirt-engine +hosted engine 4.1.1
hosts : centos 7.3 fully updated.

for full context to understand this question : 2 times in the past, when trying 
to put a host in maintenance, host stopped responding during massive migrations 
and was fenced by engine. It's still unclear why host stopped responding, but 
we think that migrating 60+ vms simultaneously puts a heavy strain on storage ? 
So we would like to better control migration process in order to better 
understand what's happening. This scenario is "production only" since our labs 
do not contain nearly as much vm with such heavy loads. So rather than trying 
to reproduce, we are trying to avoid ;)

Yes of course.  But an SPM host can fail but still maintain its connection to 
the storage lease.  In this case still you need classic fencing.

Something new we are investigating is the use of sanlock's request feature 
which allows a new host to take the lease away from the current holder.  The 
current holder would be fenced by sanlock (watchdog if necessary) and only once 
the lease is free would it be granted to the new requester.

We can use the SPM lease to kill vdsm on the non-responsive SPM host,
and start the SPM on another host, similar to the way we handle vms with
a lease.

But this does not help with the masterfs mounted on the SPM host. if vdsm
is killed before it unmount it, strating the SPM on another host (and mounting
the msasterfs on the new host) will corrupt the masterfs.

When using file based storage (nfs, glusterfs) we don't have a masterfs so
killing vdsm on the SPM should be good enough to start the SPM on another
host, even if fencing is not possible.

We can start with enabling sanlock based SPM fencing on file based storage.

[4dcc033d-26bf-49bb-bfaa-03a970dbbec1] spm vds is non responsive, stopping spm 
selection.

So that means only if BMC is up it's possible to automatically switch  SPM host?

BMC?

If your SPM is no responsive, the system will try to fence it. Did you
configure power management for all hosts? did you check that it
work? How did you simulate non-responsive host?

If power management is not configured or fail, the system cannot
move the spm to another host, unless you manually confirm that the
SPM host was rebooted.

It is absolutely necessary for any HA to work properly. There's of course the 
"confirm host has been shutdown" option, which serves as an override for the 
fence command, but it's manual

When you configure a host, there's the power management tab, where you need to 
enter the bmc details for the host. If you don't have fencing enabled, how do 
you expect the system to make sure a host running a service is actually down 
(and it is safe to start HA services elsewhere), and not, for example, just 
unreachable by the engine? How do you avoid a splitbraid -> SBA ?

There is no storage outage, but if you shutdown the spm host, the spm host

manually that the spm host was rebooted.

In a properly configured setup the SBA should take care of that. That's the

In some cases like power loss or hardware failure, there is no way to start
the spm host, and the system cannot recover automatically.

There are always corner cases, no doubt. But in a normal situation. where an 
SPM host goes down because of a hardware failure, it gets fenced, other hosts 
contend for SPM and start it. No surprises there.

Subject: [ovirt-users] How do you oVirt? Here the answers!

Hi,
a few weeks ago I opened a survey asking oVirt users about how they use oVirt.
Here are the analytics of the survey:
https://docs.google.com/forms/d/1s3k4pq_U4vHTuUUKr6dOosGj_EGFxqEisansHlqnyyM/viewanalytics#responses

Most notable facts:
- 197 responses, two times the responses we got with the 3.6 survey!
- CentOS confims as the most used distribution for running oVirt engine (89.8%) 
and Hypervisors (74.3% which become 94.2% including oVirt Node which is a 
CentOS spin)
- Fedora is the second distribution (4.6%) mostly used only for runnig oVirt 
engine
- oVirt Node jumped from 7.1% on 3.6 survey to 19.9% in 4.1!
- Surprisingly we have someone running both engine and hypervisor on Ubuntu 
based system, within VMs. I'd like to hear more about this use case.
- Within other OS we had Red Hat Enterprise Linux 6 and 7 and Scientific Linux 
(I guess 7, wasn't specified)
- Within the storage, there isn't a "winner" between NFS, Gluster and iSCSI. 
Within Other Storage, Fiber Channel is the most used. We had also: Ceph, DAS, 
EMC ScaleIO, GPFS
- Hosted Engine is the most used deployment choice with 58.4% (was 50.0% in 3.6)
- 65.8% of Hosted Engine users use it in Hyperconverged setup.

Thank you for your feedback and appreciation, we'll look into suggestions you 
sent in the survey.

That version of vdsm doesn't seem to be in the ovirt-3.6 repos - where

My plan is to continue upgrading to 4.0 and then 4.1.  Does that version

Re: [ovirt-users] iSCSI and multipath deliberation

[Pavel Gashev]

Using this logic, oVirt should detect existing storages instead of 
attaching/mounting them. The same is for networks. A VM can be placed on any 
host that has required storage(s) and network(s) attached. Datacenters/clusters 
would be virtual things.

Pros:
* Flexibility for Linux admins, wider usage
* Less code. Less bugs.
Cons:
* You must be a Linux admin to maintain oVirt instances.
* It’s a step back in RHEV/oVirt functionality. I oVirt would lose users. 
RedHat would lose customers.

Subject: [ovirt-users] iSCSI and multipath deliberation

In my opionion the main problem in configuration iscsi and multipath is that 
the ovirt developers try to start everything automaticaly during installation, 
and then during start services like vdsmd.
But during installation process adminstrator shoud choose the right multipath 
WWID identifier only.
And administrator should be responsible for setting multipath and iSCSI 
properly.
Otherwise ovirt installator does everything automaticaly in the universal way 
which is weak due to so many storage types.

Re: [ovirt-users] Suggestion for configuration with only 2 nics and equallogic ISCSI

Are you sure your 10Gbit nics doesn’t support iSCSI offload?

To: users 
Subject: [ovirt-users] Suggestion for configuration with only 2 nics and 
equallogic ISCSI

Hello,
I'm going to configure an environment where I would have:
- 2 x 1Gbit/s nics that I have to dedicate to ovirt mgmt network only, due to 
design constraints

- 2 x 10Gbit/s nics where I have to configure all other VLANS

In particular I have to define:
1) a couple of VLANs for VMs
2) VLAN for live migration (can I defined more that 1 of this kind?)
3) VLAN for iSCSI against an EQL system

EQL guys keep saying that the only supported way to connect is through 2 
different adapters and using multipath then. The iSCSI lan is on VLAN100 and I 
have to use it.

This brings in a problem in the way I can configure logical networks in oVirt 
and a scenario where I create bond on top of vlan and not the reverse as I 
normally do

The desiderata would be something like this, having the two 10Gbit nics the 
names eth2 and eth3 and vlan100 the one for iSCSI and vlan65 the one for VMs, 
for example:



eth2  --- eth2.100 -- iSCSI IP 1

\ eth2.65 ---

  \ __ bond65 -- IP

eth3  --- eth3.100 -- iSCSI IP 2  /

\ eth3.65 ---
Questions:
- does this work at all in Linux in general? I saw something with bonding 
option use_carrier=1
- in that case, can I then configure oVirt to use this configuration for 
networks?
- is LACP supporto on switch an enabler or a stopper...?

Other suggestions?

Thanks in advance,

Re: [ovirt-users] Problems adding iSCSI storage domain

Actually you have added the storage, but it’s not attached to your datacenter 
so you can’t see it your cluster.

1. Select System (root) on the tree at the left
2. Select Storage tab. Now you should able to see your storage as Unattached
3. Select your storage, and then Data Center tab
4. Attach your storage to a datacenter

the storage server. I fixed this problem but it now does not let me add the new 
storage domain as it shows "lun is already part of storage domain". The engine

there.
How do I remove this broken storage domain and then re-add it?

That´s a real shame, IMO it´s awesome to not have a native client that

I agree. I think if you could send a patch to fix this and maintain the client,

Re: [ovirt-users] best way to remove SAN lun

Please also consider a case when a single iSCSI target has several LUNs and you 
remove one of them.
In this case you should not logout.

Subject: Re: [ovirt-users] best way to remove SAN lun

Hello Nir,

I think I was not clear in my explanations, let me try again :

we have a oVirt 4.0.5.5 cluster with multiple hosts (centos 7.2).
In this cluster, we added a SAN volume (iscsi) a few months ago directly in GUI
Later we had to remove a DATA volume (SAN iscsi). Below the steps we have taken 
:

1- we migrated all disks outside the volume (oVirt)
2- we put volume on maintenance (oVirt)
3- we detach volume (oVirt)
4- we removed/destroyed volume (oVirt)

In SAN :
5- we put it offline on SAN
6- we delete it from SAN

We thought this would be enough, but later we has a serious incident when log 
partition went full (partially our fault) :
/var/log/messages was continuously logging that it was still trying to reach 
the SAN volumes (we have since taken care of the issue of log space issue => 
more aggressive logrotate, etc)

The real solution was to add two more steps, using shell in ALL hosts :
4a - logout from SAN : iscsiadm -m node --logout -T iqn.
4b - remove iscsi targets : rm -fr /var/lib/iscsi/nodes/iqn.X

This effectively solved our problem, but was fastidious since we had to do it 
manually in all hosts (imagine if we had hundreds of hosts...)

So my question was : shouldn't it be oVirt job to system "logout" and "remove 
iscsi targets" automatically when a volume is removed from oVirt ? maybe not, 
and I'm missing something?

What version? OS version?

The order must be:

1. remove the LUN from storage domain
will be available in next 4.1 release. in older versions you have
to remove the storage domain

2. unzone the LUN on the server

3. remove the multipath devices and the paths on the nodes

What do you mean by "not being completely removed"?

Who was accessing the volume?

You should have big enough /var/log to avoid such issues.

We have RFE for this here:
https://bugzilla.redhat.com/1310330

But you must understand that ovirt does not control your storage server,
you are responsible to add devices on the storage server, and remove
them. We are only consuming the devices.

Even we we provide a way to remove devices on all hosts, you will have
to remove the device on the storage server before removing it from
hosts. If not, ovirt will find the removed devices again in the next
scsi rescan,
and we do lot of these to support automatic discovery of new devices
or resized devices.

Re: [ovirt-users] Ovirt 4.0.6 guests 'Not Responding'

[Pavel Gashev]

Mark,

In your case all 30 workers were busy by vdsm.virt.sampling.HostMonitor 
discarded by timeout, and there were 3000 tasks in the queue.
I encountered the problem. In my case ISO domain was not responding.

The issue is that vdsm executor doesn’t remove discarded workers. This is a bug.

Subject: RE: [ovirt-users] Ovirt 4.0.6 guests 'Not Responding'

Hi Pavel,

Thanks for responding. I bounced the VDSMD service, the guests recovered and 
the monitor and queue full messages also cleared. However, we did keep getting 
intermittent “Guest x Not Responding “ messages being communicated by the 
Hosted Engine, in most cases the guests would actually almost immediately 
recover though. The odd occasion would result in guests staying “Not 
Responding” and me bouncing the VDSMD service again. The Host had a memory load 
of around 85% (out of 768GB) and a CPU load of around 65% (48 cores). I have 
since added another host to that cluster and spread the guests between the two 
hosts. This seems to have totally cleared the messages (at least for the last 5 
days anyway).

I suspect the problem is load related. At what capacity would Ovirt regard a 
host as being ‘full’?

Thanks,
Mark

Re: [ovirt-users] Multipath handling in oVirt

[Pavel Gashev]

Nicolas,

Take a look at
http://www.ovirt.org/documentation/admin-guide/chap-Storage/#configuring-iscsi-multipathing

The recommended way is to use different VLANs. Equallogic has to be connected 
to the different VLANs as well.

Hello,

I'm starting over on this subject because I wanted to clarify what was
the oVirt way to manage multipathing.

(Here I will talk only about the data/iSCSI/SAN/LUN/you name it networks.)
According to what I see in the host network setup, one can assign *ONE*
data network to an interface or to a group of interfaces.

That implies that if my host has two data-dedicated interfaces, I can
- either group them using bonding (and oVirt is handy for that in the
host network setup), then assign the data virtual network to this bond
- either assign each nic a different ip in each a different VLAN, then
use two different data networks, and assign them each a different data
network. I never played this game and don't know where it's going to.

At first, may the oVirt storage experts comment on the above to check
it's ok.

Then, as many users here, our hardware is this :
- Hosts : Dell poweredge, mostly blades (M610,620,630), or rack servers
- SANs : Equallogic PS4xxx and PS6xxx

Equallogic's recommendation is that bonding is evil in iSCSI access.
To them, multipath is the only true way.
After reading tons of docs and using Dell support, everything is telling
me to use at least two different NICs with different ip, not bonded -
using the same network is bad but ok.

How can oVirt handle that ?

Subject: [ovirt-users] Distribute collection of VMs

We currently use an OVA-file for Virtualbox to distribute a collection of
VMs to our customers. We would like to also support customers using oVirt.
Our VMs work if we convert the disk images to qcow2 and manually configure
the VMs. Specifically the network interface connections needs to be
configured. Is it possible to automatically import the OVA file (from the
many threads here I guess not..)?

What is the preferred method to distribute a collection of VMs for use in
oVirt?

Gianluca,

It looks like VM doesn't receive broadcasts. It can be a network topology issue.
Could you double check /sys/class/net/bond1/bonding/mode and 
/sys/class/net/bond1/bonding/slaves ?

Is it possible you have another VM with the same MAC address in the same 
network segment?

After a few minutes I loose connectivity with the guest. In this case if I go 
in guest console and ping the gateway, the connection is resumed. And I can 
maintain it if I leave the ping running, otherwise after a little I again loose 
connectivity.
I suspect it is not important but the guest is Oracle Linux 6.5 with 
3.8.13-16.2.1.el6uek.x86_64 kernel. The adapter for the vnic is the default; 
the qemu-kvm command line generated contains this:
-netdev tap,fd=29,id=hostnet0,vhost=on,vhostfd=30 -device 
virtio-net-pci,netdev=hostnet0,id=net0,mac=00:1a:4a:16:01:51,bus=pci.0,addr=0x3

I seem to remember some years ago when I used the same blades with plain 
qemu-kvm/libvirt I had to make up an ethtool setting for similar problems, but 
I don't remember what it was... and possibly I used bnx2 kernel module with the 
other embedded network interfaces, I'm not sure...

Re: [ovirt-users] 4.0 x 4.1

[Pavel Gashev]

Didi,

For example, BZ#1389251. It doesn’t look very serious. Actually “User is not 
able to edit her profile” is a side effect. Since users logged in by LDAP group 
permissions just did not have accounts in the engine, users did lose their 
access to created VMs after logout. This was a showstopper for me. Together 
with BZ#1382357 and BZ#1391146 User Portal was unusable. Fixes are simple and 
don’t affect the DB structure.

The latest nightly snapshot was broken by BZ#1402401 at the moment. I didn’t 
feel myself lucky enough to have the next snapshot without new regressions. So 
I had applied the fixes to 4.0.5.5.

Actually, you can do that proactively - if you consider upgrading to
some version, you can search bugzilla for bugs targetted to the next
one, and if any of them look serious, wait.

See my earlier reply in this thread about the risks you take by doing that.

That said, if that's what you want, you can also use the 4.0 nightly snapshot:

https://www.ovirt.org/develop/dev-process/install-nightly-snapshot/

Was using this significantly different than what you built yourself?

Best,

Re: [ovirt-users] 4.0 x 4.1

[Pavel Gashev]

Karli,

You’re right. Actually, when I did encounter the bugs in 4.0.5, all of them had 
been already found and fixed. No doubt that developers do their hard job well. 
Unfortunately, due to the holydays there was a two-month gap between releases. 
4.0.6-pre had another issue. I personally had to build my own hot-fix oVirt 
release with all the fixes and without changes under development. I can only 
guess what other users experienced.

I should really not throwing stone in glass houses here, since we´re
still running 3.6 (I know, I know), but...

If everyone thought like that, no one would have tested and gotten
those bugs fixed in 4.0.6 either, see what I´m saying?

So if people hadn´t tested and bug-reported those things, your
impression of 4.0.6 would probably have been just as bad.

Just my two cents.

I'd like to apologize for 'ugly' word. From my own personal experience 4.0.5

Re: [ovirt-users] Select As SPM Fails

[Pavel Gashev]

The fix in 4.17.35 is backported from oVirt 4.0. You will not hit it again.

Technically, vdsm 4.17.35 has been released as part of RHEV 3.6.9. So it's 
kinda recommended version if you run 3.6.

Hmmm, makes sense, thanks for the info!  I'm not enthusiastic about installing 
packages outside of the ovirt repos so will probably look into an upgrade 
regardless.  I noticed that ovirt 4 only lists support for RHEL/CentOS 7.2, 
will a situation such as this crop up again eventually as incremental updates 
for the OS continue to push it past the supported version?  I've been running 
oVirt for less than a year now so I'm curious what to expect.

You'll need to do this on each of your hosts.

The qemu-ev repo is needed to avoid dependency errors.

Hello everyone,

I'm about to start digging through the mailing list archives in search of a 
solution but thought I would post to the list as well.  I'm running oVirt 3.6 
on a 2 node CentOS7 cluster backed by fiber channel storage and with a separate 
engine VM running outside of the cluster (NOT  hosted-engine).

When I try to move the SPM role from one node to the other I get the following 
in the web interface:

[nline image 1]

When I look into /var/log/ovirt-engine/engine.log I see the following:

2017-01-18 13:35:09,332 ERROR

task-26) [6990cfca] Correlation ID: null, Call Stack: null, Custom Event ID:

When I look at the task list on the host currently holding the SPM role (in 
this case 'v6'), using: vdsClient -s 0 getAllTasks, I see a long list like this:

dc75d3e7-cea7-449b-9a04-76fd8ef0f82b :

 code = 554
 state = recovered
 tag = spm
 result =
 message = Logical Volume extend failed
 id = dc75d3e7-cea7-449b-9a04-76fd8ef0f82b

When I look at /var/log/vdsm/vdsm.log on the host in question (v6) I see 
messages like this:

The logical volume in question is an OVF_STORE disk that lives on one of the 
fiber channel backed LUNs.  If I run:

vdsClient -s 0 ClearTask TASK-UUID-HERE

for each task that appears in the:

vdsClient -s 0 getAllTasks

output then they disappear and I'm able to move the SPM role to the other host.

This problem then crops up again on the new host once the SPM role is moved.  
What's going on here?  Does anyone have any insight as to how to prevent this 
task from re-appearing?  Or why it's failing in the first place?

Beau

I built the rpms but there are some dependency errors when I attempt to

qemu-img-rhev >= 10:2.3.0-31.el7_2.16 is needed by 
vdsm-4.17.35-1.el7.centos.noarch
  
qemu-kvm-rhev >= 10:2.3.0-31.el7_2.16 is needed by vdsm-4.17.35-

These packages appear to be part of ovirt 4.0 so it looks like an
upgrade will be needed unless there is a way to obtain updated packages
for ovirt 3.6.

Re: [ovirt-users] Disk move failures

[Pavel Gashev]

Michael,

I'd recommend to build an rpm:

# yum --enablerepo=extras install -y epel-release git
# git clone https://github.com/oVirt/vdsm.git
# cd  vdsm
# git checkout v4.17.35
# yum install -y `cat ./automation/build-artifacts.packages`
# ./automation/build-artifacts.sh

Hello,

What concerns me the most is the last two errors.  I've verified that all disks

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.

Re: [ovirt-users] Storage Problem After Host Update (v3.6)

Charles,

Please note the warning in logs about lvmetad. It's better to disable this 
service if you invoke LVM utilitities manually. It caches some LVM metadata but 
VDSM doesn't use it. So technically VDSM has different view on PVs.

Subject: [ovirt-users] Storage Problem After Host Update (v3.6)

Hello,

   One of our admins did a package update on one of our 3.6 hosts 
through the web GUI and then rebooted the host.  Since then, it hasn't 
been able to properly mount storage and thus we can't move any VMs to 
it.  I rebooted it myself this afternoon and it took our whole cluster 
down for about a half hour, which was kind of concerning.

   We use multipath fibre channel for storage and when I do a vgscan or 
vgdisplay -s everything shows up correctly but I get a lot of "Duplicate 
of PV ..." warning messages.  I also get the log entries below 
constantly repeating in vdsm.log.  Any ideas what's going on and how I 
fix it?

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.

Re: [ovirt-users] How to execute Virsh command after ovirt installation ?

[Pavel Gashev]

Martin,

Thank you for the clarifications. It makes sense.

I just mean that following the Unix way [1] gives benefits. For example, VDSM 
doesn’t follow DOTADIW [2]. And I believe it could work better if it did.

Hi,

We were actually evaluating Pacemaker based hosted engine and talking
to Pacemaker developers, but we hit couple of show stoppers:

- Pacemaker supports limited set of nodes in the default setup (16
iirc, extensible using some kind of relays)
- It uses network based synchronization and requires very low latency
network (we can't guarantee that when migrations are in progress for
example) - the rest of oVirt currently uses storage based
synchronization, so we are in a different world here
- We would basically have to rewrite / duplicate most of the hosted
engine code we already have to get the same scheduling logic (load
penalization, gateway checks, ...)

We decided that rewriting code for no clear benefit was not productive
and stayed with the current hosted engine instead.

Martin

Migration to oVirt was requiring storage rearrangement. In other words, my

Re: [ovirt-users] How to execute Virsh command after ovirt installation ?

[Pavel Gashev]

It's interesting, I have an opposite opinion. I don’t see why oVirt reinvents 
its own HA instead of using Pacemaker. And it’s not old, it’s mature ;)

I my case, I had no option to setup Hosted Engine since migration to oVirt 
required storage rearrangement. Now I have to run HA oVirt VM using Pacemaker + 
DRBD. Works great.

Honestlly I don't see why in 2017 people still using the old DRBD + Pacemaker 
solution for virtualization stuff.

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.

Re: [ovirt-users] Using zRam with oVirt Nodes

[Pavel Gashev]

I enable zSwap on my oVirt nodes by default. However zSwap is not the same 
thing as zRam. The purpose of zSwap is decreasing I/O by compressing swap 
itself. zSwap uses some ram for compressed swap, but it doesn’t try to keep a 
page in memory if it can’t be compressed. 

I find using of zRam without swap too risky. You don’t know when OOM killer 
start its job.

Hello folks.

On simple libvirt/KVM hosts in order to improve RAM usage and avoid swap 
to disk I use zRam with swap to RAM technique. So create half of amount 
of host memory in zRam disk divided by the number of CPU cores. Works 
pretty well.

Has anyone tried it with oVirt Nodes or even has it been considered as a 
feature to simply turn on/off ?

[ovirt-users] vdsm 4.17

[Pavel Gashev]

Hello,

I’ve found that vdsm 4.17.32 doesn’t work well in CentOS 7.3 due to bugs like
https://bugzilla.redhat.com/1364339 or https://bugzilla.redhat.com/1368258
However it seems like vdsm 4.17.35 has all related fixes.

Is it safe to use non-released version of vdsm?
Is there a plan to release oVirt 3.6.8?

Interesting, those aren't actually UI failures, those appear to be failures
from backend requests. As in, get me some data, and the query fails for some
reason, there should be something in the engine log. Let me dig up the ones

[ovirt-users] User portal permissions

[Pavel Gashev]

Hello,

I’d like to use the User Portal. Unfortunately, I’ve found no documentation 
about setting it up.
How to give a way for a user to create and manage VMs within a quota? Which 
permissions should I set for Network/Storage/Cluster?

Any help is appreciated.

Also the guest tools installer doesn’t install the QEMU service, so it’s

Re: [ovirt-users] shutdown and kernel panic

[Pavel Gashev]

Luigi,

It’s necessary to put a host into maintenance mode before shutdown.

That panic is a kernel reaction to NMI, which is triggered by hardware 
watchdog, which is set by wdmd daemon, which is used by sanlock. This scheme is 
intended to hardware reset a server if it has lost connection to its storage 
when lock is acquired.

On HP servers it’s necessary to configure watchdog to do hardware reset instead 
of NMI in BIOS settings.

Are you sure Pavel ?

As far as I know and it has been discussed in this list before, the 
limitation is in CLVM which doesn't support Thinprovisioning yet. LVM2 
does, but it is not in Clustered mode. I tried to use GFS2 in the past 
for other non-virtualization related stuff and didn't have much success 
either.

What about OCFS2 ? Has anyone ?

Fernando,

oVirt supports thin provisioning for shared block storages (DAS or iSCSI). It 
works using QCOW2 disk images directly on LVM volumes. oVirt extends volumes 
when QCOW2 is growing.

I tried GFS2. It's slow, and blocks other hosts on a host failure.

Using traditional CLVM is far from good starting because of the lack of 
Thinprovision so I'm willing to consider either of the Filesystems.

The network bridge is added successfully, but applying the bridge to the

My system:

6 HV nodes running CentOS 7 and OV version 4
1 Dedicated engine running CentOS 7 and engine version 4 in 3.6 mode.

The HV nodes all have Mellanox IB cards, dual port. Port 0 is for iSCSI

Or write your own hook [1] that will cleanly do whatever

Re: [ovirt-users] Local and Shared storage in same datacenter

[Pavel Gashev]

I think it's all about online VM migration. oVirt doesn't support online VM 
migration together with online storage migration. So any storage has to be 
accessible from any hosts in a datacenter. That's why local storages are too 
restricted.

Converting Local storages to Shared removes the restriction. Avoiding NFS layer 
locally removes the NFS performance drawback. And both allow to adhere to the 
oVirt way.

Why this 'workdaround' to share a local storage as NFS instead os just 
use it as a 'normal' Local storage ? Looks more like a chewing gum.

Is there any work in progress to change the way this storage pool 
manager works ?

Re: [ovirt-users] Local and Shared storage in same datacenter

[Pavel Gashev]

Mike,

As workaround it's not very hard to create a mount command wrapper that 
converts local NFS mounts to bind-mounts. The propper way I think is to patch 
the VDSM service to handle local NFS mounts. In result, a NFS storage will work 
like a local storage if it's local.

I installed a nfs server on the hypervisor and am using it that way at 
the moment.
It feels 'wrong' but it seems to work okay and it is fast as far as I 
can tell.
Still would like to see another solution without the added latency of 
nfs and be able to utilize directio, etc.

Re: [ovirt-users] Local and Shared storage in same datacenter

You can share and use your local storage via NFS. So all your storages are 
shared, and can be used in the same datacenter.

Subject: [ovirt-users] Local and Shared storage in same datacenter

Hi guys,

There have been a few related questions already that I could find, but I 
did not find anything relating to my specific use case.

Currently it is not possible to mix local storage with shared storage in 
the same datacenter.
The reason seems to be because of the storage pool manager (SPM).
This is a role in the datacenter provided to one specific host.

While I understand that this makes having local storage impossible, I 
believe there is a use case to have local storage in a shared storage 
datacenter.
Consider the following:
I have a few applications that require 1 milli second latency and at 
most 2 milli second.
That is not consistenly achievable with shared storage, to that end I 
added flash storage to a few hypervisors.
About 5% of my servers require this and are not that resource hungry to 
require a dedicated physical server.
That same 5% also has no requirement to be migrated if a host fails.

So in short I have 5 heavy hosts running ovirt with a shared storage 
domain on NFS for 95% of my servers.
All running fine, but I am now unable to run my remaining 5%.

To finish up my summary I have been testing various virtualization 
technologies, like VmWare and Hyper-V.
They allow such configurations as I mentioned.

I already had some chat on irc with various guys and they suggested that 
I put this on the mailing list, so here goes.

My suggestion would be to evoluate from SPM to SDM.
SDM stands for Storage Domain Manager.
This would create the possibility to have all nodes in the datacenter 
participate in the storage handling.
A extra benefit would be that local storage could be added.

What do you think?

Thanks for reading.

Re: [ovirt-users] remote-viewer on OSX

SpiceViewer is quite old. It just doesn't work well. Two issues:
1. It's slow. It takes the whole couple seconds to scroll text screen

2. It tries to hide the mouse cursor in the bottom right corner. This
activates Hot Corners action.

HTML5 spice viewer doesn't work well too if you have QXL drivers

You can use vdsClient without password:

For virsh you can set your own password:

# saslpasswd2 -f /etc/libvirt/passwd.db -c root

Re: [ovirt-users] Migration Failure Due to network

[Pavel Gashev]

Alexis,

Use "Clusters" -> "Logical Networks" -> "Manage Networks" for assigning
network for migrations. It's ovirtmgmt by default. Note that migration
network has to have IPs on hosts.

Hosts have VDSM configuration option - [vars]/migration_max_bandwidth
in /etc/vdsm/vdsm.conf. It's 52MB/s by default. So it looks like your
network is already highly used.

Your VM migration fails because migration is so slow so it just can't
migrate without downtime. You can adjust "Use custom migration
downtime" VM option to make any VM migrated over any network. Please
note it's a maximal value. Actually it starts with a value 10 times
lower and increases it automatically. 5000 is good value to start in
your case.

Re: [ovirt-users] CARP Fails on Bond mode=1

[Pavel Gashev]

In mode=1 the active interface sends traffic, but both interfaces accept 
incoming traffic. Hardware switches send broadcast/multicast/unknown 
destination MACs to all ports, including the passive interface. So packet sent 
from the active interface can be received back from the passive interface. 
FreeBSD CARP just would go mad when it receives its own packets.

I believe if you get Linux implementation, it will work well in the same 
network setup. I use keepalived in oVirt VMs with bonded network, and have no 
issues.

How can it lead into packet duplication when the passive should not be
active and only it's mac-address should be visible on the switch to
prevent confusion on the switch ?

For a VRRP setup on the switch there is no other option then mode=1 as
far as I know ?

I have been testing bonding with a vm connected to the network on this

It seems that when the VM which holds the Carp IP and so is Master you
can ping both IP's, so interface IP and Carp IP, but you cannot

You can route traffic over the interface IP of the Carp Slave.

Is this known or just not possible ?

Re: [ovirt-users] VM convert Windows2012R2 to Ovirt

[Pavel Gashev]

It's the ovirt guest tools iso.

Please note there is a warning message at the import dialog – «You have 
selected windows OS and have not selected VirtIO drivers. This may cause the 
system not boot up». However selecting the ovirt guest tools iso doesn't help.

Looks like the only solution is to install the virtio-win package on the host. 
Nothing depends on it so it's not installed by default.

I've just converted a Windows 2012R2 VM, and it boots without issues.

First of all, please ensure that the configured system matches the actual

Also please let me know what is the supported CPU Family on your cluster?

[ovirt-users] Security Groups

[Pavel Gashev]

Hello,

Currently oVirt supports network security groups for OpenStack network provider 
only. Are there plans to implement Security Groups for native networks?

Technically, I can configure a vNic profile with some Security Groups UUID, and 
apply it in before_device_create and before_update_device VDSM hooks as 
filterref to some custom nwfilter. The only issue is that I have to manually 
edit and distribute nwfilter xml among hardware nodes. If I want isolate set of 
VMs, I have to manually maintain MAC addresses of VMs in that xml.

It would be great if oVirt web interface had a nwfilter editor. Are there plans 
for it?

Thanks

Re: [ovirt-users] best way to migrate VMs from VMware to oVirt

[Pavel Gashev]

Basically, I boot windows in safe mode and remove vmware tools. In this case I 
was able to use old VM if there are issues with conversion. Of course you can 
remove vmware tools before migration.

Linux VMs do not need the convertor. The procedure is much simpler:
1. Make sure you don't use device names in /etc/fstab and grub
2. Make sure initramfs has required drivers:
dracut -f --add-drivers "virtio virtio_net virtio_blk virtio_scsi virtio_pci"
3. Create appropriate VM in oVirt. Disks must be in raw format (default), but 
sparse. NICs must have the same MACs.
4. Hard link vmware and ovirt disk images, and fix permissions (chown 36:36 / 
chmod 0660)
5. Shutdown VM in vmware and immediately start VM in oVirt

Cam,

I did import vmware VMs, but it was not an easy procedure. Last time I did it, 
there were the following issues:
* oVirt engine didn't support 32bit VMs. If you have a 32bit VM in vCenter, you 
are not able to see the list VMs to import.
* There were issues if you have a cluster in vCenter. I had to setup a proxy 
server to fix URLs on the fly, but then I've found a better way. See below.
* RHEL/CentOS virt-v2v does't support 2012 and greater. I had to use virt-v2v 
from Fedora.

Thus, if you want to convert it manually, the procedure is the following:
1. Install vdsm-hook-nestedvt on ovirt nodes, and reboot
2. Setup a VM with latest Fedora, install virt-v2v.
3. Mount your NFS storage inside v2v VM.
4. Move windows VMs to the same NFS storage.
5. Connect to vcenter using the following command:
virsh -c vpx://vcenter/Folder/Datacenter/Cluster/server?no_verify=1
6. Find windows VM using 'list' command, and dump config using 'dumpxml 
VMNAME/ID'
7. Edit the xml providing full path to vmdk images (see «source file=»)
8. Create appropriate VM in oVirt
9. Find new VM IDs using ovirt-shell
10. Make sure the source VM is stopped
11. Execute virt-v2v (make sure:
virt-v2v -v -x -i libvirtxml VM.xml -o vdsm -of qcow2 -os 
/nfs/b1b74392-8f46-4a25-aeef-5344ac692c73 --vdsm-image-uuid

421e93a8-33d2-fc0e-4cfc-ac45a35db8c9
12. Fix resulting disk pemissions (chown 36:36 / chmod 0660)
13. Now you can start VM in oVirt. Remove vmware tools, and install oVirt tools 
and drivers.

I hope this helps.

Cam,

I believe the URL must be the following:
vpx://ARDA%5ccam@nssesxi-mgmt/Systems/North%20Sutton%20Street/nssesxi/nssesxi04-mgmt?no_verify=1
or
vpx://ARDA%5ccam@nssesxi-mgmt/North%20Sutton%20Street/Systems/nssesxi/nssesxi04-mgmt?no_verify=1

Hi,

I am trying to import and convert some VMWare guests from a VMWare cluster with 
vCenter version 6, to a KVM (oVirt) host. The KVM node (RHEL 7.2) has virt-v2v 
1.28.1, though I've also tried using Fedora 23 which has 1.32.4.

The details are:

vCenter server: nssesxi-mgmt
Datacenter name: North Sutton Street
esxi server which runs the VM: nssesxi-mgmt04
folder name: Systems
VM name: wvm2
cluster name: nssesxi

I tried via the 'Import' option in the oVirt GUI, and put the details above in, 
and after thinking about it for a while, it returns a 500 internal server 
error. As I'm authing against AD, I put my username as cam@ARDA. I have 
attached the log (gzipped).


I've also tried via the command line, and the result is much the same. I did 
post the below to the libvirt-users mailing list but have not had a response, 
so I thought I'd see if anyone here might know what is going on.

Unfortunately, spaces were put in the name of the datacenter, so I escape them 
with %20

So the final URI is constructed as:

vpx:/ 


The error I get is:

Re: [ovirt-users] best way to migrate VMs from VMware to oVirt

[Pavel Gashev]

Cam,

I did import vmware VMs, but it was not an easy procedure. Last time I did it, 
there were the following issues:
* oVirt engine didn't support 32bit VMs. If you have a 32bit VM in vCenter, you 
are not able to see the list VMs to import.
* There were issues if you have a cluster in vCenter. I had to setup a proxy 
server to fix URLs on the fly, but then I've found a better way. See below.
* RHEL/CentOS virt-v2v does't support 2012 and greater. I had to use virt-v2v 
from Fedora.

Thus, if you want to convert it manually, the procedure is the following:
1. Install vdsm-hook-nestedvt on ovirt nodes, and reboot
2. Setup a VM with latest Fedora, install virt-v2v.
3. Mount your NFS storage inside v2v VM.
4. Move windows VMs to the same NFS storage.
5. Connect to vcenter using the following command:
virsh -c vpx://vcenter/Folder/Datacenter/Cluster/server?no_verify=1
6. Find windows VM using 'list' command, and dump config using 'dumpxml 
VMNAME/ID'
7. Edit the xml providing full path to vmdk images (see «source file=»)
8. Create appropriate VM in oVirt
9. Find new VM IDs using ovirt-shell
10. Make sure the source VM is stopped
11. Execute virt-v2v (make sure:
virt-v2v -v -x -i libvirtxml VM.xml -o vdsm -of qcow2 -os 
/nfs/b1b74392-8f46-4a25-aeef-5344ac692c73 --vdsm-image-uuid 
368487a5-d7f2-43d2-bd61-d15abbc5c482 --vdsm-vol-uuid 
2f56c6cd-a212-44e6-a792-447787f5b073 --vdsm-vm-uuid 
421e93a8-33d2-fc0e-4cfc-ac45a35db8c9
12. Fix resulting disk pemissions (chown 36:36 / chmod 0660)
13. Now you can start VM in oVirt. Remove vmware tools, and install oVirt tools 
and drivers.

I hope this helps.

We don't configured anything regarding network used for nfs storage, so it works
just like any other nfs mount you create yourself.

Re: [ovirt-users] oVirt Windows Guest Tools & Live Migration issues.

[Pavel Gashev]

It seems guest tools installer is broken at least for Windows 2012 R2. It 
installs files into Program Files, but doesn't actually install drivers and 
QEMU guest tools. No errors, it reports that everything is ok, but it's not. 
oVirt guest tools is installed and work properly.

Workarounds are the following:
1. Start Device Manager and make sure all devices have drivers. Install drivers 
from «C:\Program Files (x86)\oVirt Guest Tools\drivers» if needed. Do not 
install video driver.
2. Start «C:\Program Files (x86)\oVirt Guest Tools\drivers\qemu-ga-x64.exe» 
manually.
3. Rename «C:\Program Files (x86)\oVirt Guest Tools\drivers\Balloon\2k12R2» 
into «…\w2k12R2», otherwise installed balloon service doesn't start.

Hello Michal,

Guest tools are working and getting all details about guest vm as needed.

But one thing I didn't understand. What is the relationship between

guest services does not start.

Also, how do we install memory baloon driver?

Tomorrow morning, I will post about Live Migration events after I attempt it.

Windows Guests Agents - Where do I download them from? Not getting the proper

Hi Anantha,
it’s part of ovirt-guest-tools. See 
http://lists.ovirt.org/pipermail/users/2016-May/039779.html


Live migration failure - These are pretty busy VMs if not big. The event does 
not show any specific message but just as migration failed. Is the reason 
logged somewhere? Please share the log location so that I can check & share the 
log for meaningful message and proper screen shots.

There should be more details in the events at the bottom of the webadmin page 
(just make it a bit bigger it may not be te last message)
If they are busy VMs then you may have issues migrating them. There is some 
simple tuning available and it may help. You can increase the maximum downtime 
in VM properties dialog (500ms by default, you can go up to whatever is 
feasible for your VM, seconds, tens of seconds)
Bandwidth is limited to work on 1Gb network, if you have 10Gb availabl you can 
also tune /etc/vdsm.conf on each host and increase the maximum bandwidth 10 
times

Hi,

We have just installed oVirt 3.6 on 3 hosts with storage volumes on Fibre

1. We have created 15 Virtual Machines all VM with Windows Server 2012 R2 OS. 
VM properties does not report the Operating System nor it shows the IP and FQDN 
in the Admin Portal. There is always an exclamation mark that reports about OS 
being different from the template and timezone issues. We have changed the 
timezone to Indian Standard Time in both VM and Host, same result continues. We 
have installed Windows Gues Tools, same result continues. Screen shot is below.

you doesn’t seem to run the guest agent. Make sure the service is started and 
works, then you’ll see IPs and more detailed info about each guest, and 
exclamation marks should go away





2. When we manually tried to migrate the VMs from one host to another one, the 
migration gets initiated, but will eventually fail.

Any specific setting missing here or is it a bug.

are they big or busy VMs? What does it fail on? There should be a menaingful 
message even if it’s just a timeout



Note:

All hosts are installed with CentOS 7.2 minimal installation oVirt node is 
installed and activated.
We do not have a DNS in our environment. We have to do with IPs.

as long as engine works with FQDN it’s ok


We are yet to apply the 3.6.6 patch on Engine and Nodes.

that may help with some of the issues above, so please try to do that

Thanks,

Re: [ovirt-users] What recovers a VM from pause?

[Pavel Gashev]

Please note that it's necessary to add a magic line '# VDSM PRIVATE' as second 
line in /etc/multipath.conf. Otherwise vdsm would overwrite your settings.
Thus, /etc/multipath.conf should start with the following two lines:
# VDSM REVISION 1.3
# VDSM PRIVATE


On Mon, 2016-05-30 at 22:09 +0300, Nir Soffer wrote:

But you may modify multipath configuration on the host.

We use now this multipath configuration (/etc/multipath.conf):

# VDSM REVISION 1.3

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
deferred_remove yes
}

devices {
device {
all_devsyes
no_path_retry   fail
}
}

This enforces failing of io request on devices that by default will queue such
requests for long or unlimited time. Queuing requests is very bad for vdsm, and
cause various commands to block for minutes during storage outage,
failing various
flows in vdsm and the ui.
See https://bugzilla.redhat.com/880738

However, in your case, using queuing may be the best way to do the switch
from one storage to another in the smoothest way.

You may try this setting:

devices {
device {
all_devsyes
no_path_retry   30
}
}

This will queue io requests for 30 seconds before failing.
Using this normally would be a bad idea with vdsm, since during storage outage,
vdsm may block for 30 seconds when no paths is available, and is not designed
for this behavior, but blocking from time to time for short time should be ok.

I think that modifying the configuration and reloading multipathd service should
be enough to use the new settings, but I'm not sure if this changes
existing sessions
or open devices.

Re: [ovirt-users] failing update ovirt-engine on centos 7

I had an issue with updating to 3.6.6. There were errors during engine-setup:

[ ERROR ] Yum Non-fatal POSTUN scriptlet failure in rpm package 
ovirt-vmconsole-1.0.0-1.el7.centos.noarch

[ ERROR ] Yum Transaction close failed: Traceback (most recent call last):

ovirt-vmconsole has the following uninstall script:
postuninstall scriptlet (using /bin/sh): 
if [ "$1" -ge "1" ]; then
semodule -i

In other words you can't update if you have SELINUX disabled.

The workaround is the following:
ln -fs /bin/true /usr/sbin/semodule

Re: [ovirt-users] Do you use ovirt-engine-reports?

[Pavel Gashev]

I use Reports. Basically, it's «Five Most Utilized…» and «Inventory» reports. 

It would be great if oVirt had the following functionality instead of Reports:
1. Columns with absolute values of CPU/Network/Disk IO for refresh interval and 
absolute values of Memory/Disk Usage in the Virtual Machines list. Together 
with existing filtering and column sorting it would give a great «virt-top» 
like functionality.
2. Ability to export any table to a CSV file.

Re: [ovirt-users] Trying to understand the mixed storage configuration options.

[Pavel Gashev]

Nir,

Basically, almost any server has a local storage. It could be a reliable, RAID 
enabled storage. It would be great to allow to use it simultaneously with 
shared storages.

Other virtualizations like vmware/hyperv support local and shared storages 
simultaneously. If your VM is on local storage, it's tied to a host. Just like 
when VM has attached local device(s). VM migration moves disks between hosts as 
well.

An obvious solution is to export local storages via NFS to make it shared. This 
would allow to drop «local storage datacenters» as a class.

TODO list would be the following:
1. VDSM: add creating NFS exports
2. Engine: creating NFS exports before local storage activation, and updating 
NFS exports after adding/removing hosts
3. Engine: add moving disks between storages during (just before, just after) 
VM migration. 
4. Engine: add constraints to avoid dangerous situations - disallow changing VM 
startup host, disallow moving disks to another local storage without VM 
migration, etc.

Re: [ovirt-users] stalls during live Merge Centos 7 / qemu 2.3

[Pavel Gashev]

It really works. The bug is that engine doesn't update the state of 
finalization step. Engine.log shows that finalization is actually finished. 
Restart of engine fixes it. Also it's possible to fix it in directly in 
database w/o restarting anything.

Hi,

I was just annoyed that during my tests I got a second error. For me
it seemed as finally everything worked fine. Although the single disk live
merge task was shown to be still running finally.

Nevertheless after Nirs explanation for BZ1326900 I'm unsure if the single
disk live merge really works. So we currently have the following situation:

Live merge (for all disks) stalls the VM

Live merge (for single disks) seems to work but logs give other info.
