Hi,
we have a problem in oVirt that highly available VMs don't restart after host poweroff because Vdsm identifies the case as a user initiated shutdown (https://bugzilla.redhat.com/1800966).
When poweroff is run on the host, libvirt-guests service takes an action.
If oVirt is initiating a graceful host shutdown,
I meant host shutdown not initiated by oVirt.
Well oVirt still knows at any point in time what VMs are currently running on a host, so if it sees the host shutdown, it already knows that needs restarting.
libvirt-guests ensures graceful shutdown of the VMs (which is a good thing) so at the moment when the host gets down, there are no VMs running there. We need that info at the moment when a VM is shut down and I think we can get it by examining some systemd service (if ignoring some not so important timing issues). Regards, Milan
