yes they are still saying "paused" state.<br>
No, bouncing libvirt didn't help.<br>
<br>
I noticed the errors about the ISO domain. Didn't think that was
related.<br>
I have been migrating a lot of VMs to ovirt lately, and recently
added another node.<br>
Also had some problems with /etc/exports for a while, but I think
those issues are all resolved.<br>
<br>
<br>
Last "unresponsive" message in vdsm.log was:<br>
<br>

<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 unresponsive”)</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 unresponsive”)</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>
<div>If not…then I would suspect the “vm recovery” code not
working correctly. Milan is looking at that.</div>

<pre class="" wrap="">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?

<pre class="" wrap="">I have a hardware node that has 26 VMs.
9 are listed as "running", 17 are listed as "paused".
In truth all VMs are up and running fine.
I tried telling the db they are up:
engine=> update vm_dynamic set status = 1 where vm_guid =(select
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>
</blockquote>
<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.
</pre>
<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.
Adding Michal in case he has better idea how to proceed.
