2015-07-28 19:29:33.153 23754 ERROR nova.cells.messaging
The exception being raised is
http://git.openstack.org/cgit/openstack/nova/tree/nova/objects/instance.py?id=a74f07a92356187d3455e5a9e2418fb1ea697f96#n614
What's happening is that the instance does not exist in the cell so
instance.destroy is being called with an instance object instantiated
like "objects.Instance(context=ctxt, uuid=instance.uuid)" so
instance.id is not set. So we should probably try to look up the
instance when this failure occurs in instance_destroy_at_top.
