Do you mean that you've done xm create <file>, xm shutdown <domain>, and
then xm create <file> again? You are right, this will in effect create
two separate VMs, with the same configuration, but different identities
(and different UUIDs).
If you use the new support for persistent VMs, then you should find
that the VM retains its identity. xm new <file>, xm start <domain>,
xm shutdown <domain>, xm start <domain> should have the same effect as
the commands above, but you will see that the VM retains its UUID.
