Ah ha.... that makes the domain go away.

Ok, to be clear what I did....

xl create -e domain-details
xl shutdown <domain>
(End up with a domain called (null) in state --ps-d according to xl list
kill the qemu-dm process associated with the domain
the domain goes away

note that I didn't need to do an 'xl destroy' the kill of qemu-dm was

If I do....

xl create -e domain-details
xl destroy <domain>
the domain goes away
