Public bug reported:

When doing a live migration of an instance using ceph for shared
storage, if the migration fails then the instance directory will not be
cleaned up on the destination host. The next attempt to do the live
migration will fail with DestinationDiskExists, but will cleanup the
directory.

A simple way to test this is to setup a working system which allows a
ceph instance to be live migrated, then delete the relevant ceph secret
from libvirt on one of the hosts. Live migration to that host will fail,
triggering this bug.
