I think the question is what happens when the host goes down. To me, the right way to shutdown a host is putting it first to maintenance (VM evacuate to other hosts) and then shutdown. On emergency shutdown without moving the host to maintenance first I think libvirt is communicating the host is going down to the guests and tries to cleanly shutdown vms while the host is going down.
