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, then surely it already knows what VMs it has running on the host at that time, and so has enough info to restart them later.
`virsh shutdown' is run on the VM, the guest OS is shut down cleanly and libvirt reports a shutdown event with VIR_DOMAIN_EVENT_SHUTDOWN_GUEST detail. Although it is a host initiated shutdown actually.
Does libvirt provide any means to distinguish this case from a regular user shutdown?
A "virsh shutdown" merely triggers a request to the guest OS to start a guest initiated shutdown. As such it is indistinguishable from an administrator initiating the same thing inside the guest.
