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 = '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.

you need to run virsh in read-only mode virsh -r list —all

tried systemctl restart libvirtd. No change.

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.
