In general VMs are not restarted after an unexpected shutdown, but HA VMs
are restarted after failures.

If the HA VM has a lease, it can restart safely on another host regardless of
the original host status. If the HA VM does not have a lease, the system must
wait until the original host is up again to check if the VM is still
running on this
host.

Arik can add more details on this.
