Get out of jail for VMs that won't reboot. Warning: I have no idea why this works or what the implications of the 'destroy_domain' command are but this is how I'm recovering my hung VMs:

Destroy the domain.
xe vm-reboot uuid=<UUID> --force
Force a reboot of the VM.
There are 3 alternatives - vote for the best!
