Doc Text:	A denial of service flaw was found in the OpenStack Compute (nova) instance migration process. Because the migration process does not terminate when an instance is deleted, an authenticated user could bypass user quota and deplete all available disk space by repeatedly re-sizing and deleting an instance.
