The VM is in VDSM cache and doesn't really exist so its excepted that
the destroy would fail.(exception are always unexpected )
a restart to VDSM will help here:
$ service vdsmd restart
you can track the VDSM log:
/var/log/vdsm/vdsm.log
and the engine should be recovering too now.
let us know if you got things working.
