Why does the engine think the VMs are paused?

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 vdsm, restarting vdsm may fix this.

If this does not help, maybe this is libvirt issue? did you try to check vm
