Then my suspicion of vm recovery gets closer to a certainty:)
<div>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. </div>

<div>yes, that time looks correct. Any idea what

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 class="">
</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 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)</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 “monitor
unresponsiveâ€)</div>
<div><br class="">
</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>

looking at that.</div>

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 = '<a moz-do-not-send="true" href="http://api1.test.j2noc.com" class="">api1.test.j2noc.com</a>');
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 class="" wrap="">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 class="" wrap="">this looks more likely as it seems such status is being reported
logs would help, vdsm.log at the very least.

<blockquote type="cite" class="">
<pre class="" wrap="">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.
