Yes I did "systemctl restart libvirtd" which apparently also restart =
vdsm?
yes, it does.=20

Looks like problem started around 2016-04-17 20:19:34,822, based on =
engine.log
attached.
yes, that time looks correct. Any idea what might have been a trigger? =
Anything interesting happened at that time (power outage of some host, =
some maintenance action, anything)?=20
logs indicate a problem when vdsm talks to libvirt(all those "monitor =
become unresponsive=E2=80=9D)
It does seem that at that time you started to have some storage =
connectivity issues - first one at 2016-04-17 20:06:53,929. And it =
doesn=E2=80=99t look temporary because such errors are still there =
couple hours later(in your most recent file you attached I can see at =
23:00:54)
When I/O gets blocked the VMs may experience issues (then VM gets =
Paused), or their qemu process gets stuck(resulting in libvirt either =
reporting error or getting stuck as well -> resulting in what vdsm sees =
as =E2=80=9Cmonitor unresponsive=E2=80=9D)
Since you now bounced libvirtd - did it help? Do you still see wrong =
status for those VMs and still those "monitor unresponsive" errors in =
vdsm.log?
If not=E2=80=A6then I would suspect the =E2=80=9Cvm recovery=E2=80=9D =
code not working correctly. Milan is looking at that.
Thanks,

There's a lot of vdsm logs!

yes they are still saying "paused" state.
No, bouncing libvirt didn't help.
I noticed the errors about the ISO domain. Didn't think that was related.
I have been migrating a lot of VMs to ovirt lately, and recently added
another node.
Also had some problems with /etc/exports for a while, but I think those
issues are all resolved.
Last "unresponsive" message in vdsm.log was:
vdsm.log.49.xz:jsonrpc.Executor/0::WARNING::*2016-04-21*
11:00:54,703::vm::5067::virt.vm::(_setUnresponsiveIfTimeout)

yes, that time looks correct. Any idea what might have been a trigger?
Anything interesting happened at that time (power outage of some host,
some maintenance action, anything)?
logs indicate a problem when vdsm talks to libvirt(all those "monitor
become unresponsiveâ)
It does seem that at that time you started to have some storage
connectivity issues - first one at 2016-04-17 20:06:53,929. And it
doesnât look temporary because such errors are still there couple
hours later(in your most recent file you attached I can see at 23:00:54)
When I/O gets blocked the VMs may experience issues (then VM gets
Paused), or their qemu process gets stuck(resulting in libvirt either
reporting error or getting stuck as well -> resulting in what vdsm
sees as âmonitor unresponsiveâ)
Since you now bounced libvirtd - did it help? Do you still see wrong
status for those VMs and still those "monitor unresponsive" errors in
vdsm.log?
If notâŠthen I would suspect the âvm recoveryâ code not working
correctly. Milan is looking at that.
Thanks,
michal

Then my suspicion of vm recovery gets closer to a certainty:)
Can you get one of the paused vm's .recovery file from /var/lib/vdsm
and check it says Paused there? It's worth a shot to try to remove
that file and restart vdsm, then check logs and that vm status...it
should recover "good enough" from libvirt only.
Try it with one first

It does seem that at that time you started to have some storage
connectivity issues - first one at 2016-04-17 20:06:53,929. And it
doesn’t look temporary because such errors are still there couple hours
later(in your most recent file you attached I can see at 23:00:54)
When I/O gets blocked the VMs may experience issues (then VM gets Paused),
or their qemu process gets stuck(resulting in libvirt either reporting

Since you now bounced libvirtd - did it help? Do you still see wrong

If not…then I would suspect the “vm recovery†code not working
correctly. Milan is looking at that.

vdsm-4.17.18-0.el7.centos.noarch
the vdsm.log attach is good, but it’s too short interval, it only shows recovery(vdsm
restart) phase when the VMs are identified as paused….can you add earlier logs? Did you
restart vdsm yourself or did it crash?
libvirt-daemon-1.2.17-13.el7_2.4.x86_64
Thanks.

In truth all VMs are up and running fine.
I tried telling the db they are up:

vm_guid from vm_static where vm_name = 'api1.test.j2noc.com');
GUI then shows it up for a short while,
then puts it back in paused state.

Why does the engine think the VMs are paused?
Attached engine.log.
I can fix the problem by powering off the VM then starting it back up.
But the VM is working fine! How do I get ovirt to realize that?
If this is an issue in engine, restarting engine may fix this.
but having this problem only with one node, I don't think this is the issue.
If this is an issue in vdsm, restarting vdsm may fix this.
If this does not help, maybe this is libvirt issue? did you try to check vm
status using virsh?
this looks more likely as it seems such status is being reported
logs would help, vdsm.log at the very least.
If virsh thinks that the vms are paused, you can try to restart libvirtd.
Please file a bug about this in any case with engine and vdsm logs.
Adding Michal in case he has better idea how to proceed.

<div>yes, that time looks correct. Any
idea what might have been a trigger?
Anything interesting happened at
that time (power outage of some
host, some maintenance action,
anything)? </div>
<div>logs indicate a problem when vdsm
talks to libvirt(all those "monitor
become unresponsiveâ )</div>
<div><br>
</div>
<div>It does seem that at that time
you started to have some storage
connectivity issues - first one
at 2016-04-17 20:06:53,929. And it
doesnât look temporary because
such errors are still there couple
hours later(in your most recent file
you attached I can see at 23:00:54)</div>
<div>When I/O gets blocked the VMs may
experience issues (then VM gets
Paused), or their qemu process gets
stuck(resulting in libvirt either
reporting error or getting stuck as
well -> resulting in what vdsm
sees as âmonitor unresponsiveâ )</div>
<div><br>
</div>
<div>Since you now bounced libvirtd -
did it help? Do you still see wrong
status for those VMs and still those
"monitor unresponsive" errors in
vdsm.log?</div>
<div>If notâŠthen I would suspect the
âvm recoveryâ code not working
correctly. Milan is looking at that.</div>

In truth all VMs are up and running fine.

GUI then shows it up for a short while,
then puts it back in paused state.

Why does the engine think the VMs are paused?
Attached engine.log.
I can fix the problem by powering off the VM then starting it back up.
But the VM is working fine! How do I get ovirt to realize that?
</pre>
</blockquote>
<pre>If this is an issue in engine,
restarting engine may fix this.
but having this problem only with one node, I don't think this is the issue.
If this is an issue in vdsm, restarting vdsm may fix this.
If this does not help, maybe this is libvirt issue? did you try to check vm
status using virsh?
</pre>
</blockquote>
<pre>this looks more likely as it
seems such status is being reported
logs would help, vdsm.log at the very least.

<blockquote type="cite">
<pre>If virsh thinks that the vms

Please file a bug about this in any case with engine and vdsm logs.
Adding Michal in case he has better idea how to proceed.

Thank you for the information. I was able to reproduce the problem with
mistakenly reported paused state when Vdsm receives unexpected data from
libvirt. I'll try to look at it.
Restarting Vdsm (4.17.18 and some newer versions) afterwards remedies
the problem for me, even without removing the recovery file.

New subject: vms in paused state
We've found out that if libvirtd got restarted then VMs with disabled
memory balloon device are wrongly reported as being in the paused state.
It's a bug and we're working on a fix.
