Open Stack

Fortunately,  this bug get fixed in final Havana stable release 2013.2.4
see https://review.openstack.org/#/c/87455,  but you need to be aware that
this change also
renames instance disk name from instance-0000000xx to uuid format, so after
upgrade to this version, you should ensure not previous instances exists or
old instance disk files in rbd store can't be removed. Sorry I didn't catch
this early, or this can be improved within a line of code to get fixed.
