We don't restart the VM in that case on purpose, since we really don't know
what's the status of the VM - the host might have been just disconnected from
the network while the VM is still running (and connected to the storage),
so if we'll also run the VM on a different host, we'll get "split-brain".

In order to restart HA VMs which were running on host that went down, you either
needs to have power-management defined for that host (for automatic restart) or
to trigger it manually by selecting "confirm host has been rebooted" when the
host is changed to non-responsive state (and you need to have additional host
which is up of course).
