If your server crashed, you can't migrate a VM as far as I know. Open
Nebula will fails to "stop" the process on crashed server.
Usually, a crashed server leads to a VM lost. Your disk may even be
corrupted.

If what you need is high availability, you would need a high
availability supported app with load balancing or failover mechanisms.

IF you really need to restore this VM, I suppose you can copy the saved
state of the VM disk and use it as a new image.
