Public bug reported:

In the code of create image for volume based instance
http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/api.py#n2610,
there isn't rollback code when create volume snaphost or create image
failed. For example, both cinder and glance have quota for the number of
volume snapshot and the number of image metadata, so there have a chance
to failed on quota. But the code won't rollbacked already created volume
snapshot.
