Libvirt RBD image backend support for glance multistore
Currently, Nova does not support a deployment where there are multiple
Ceph RBD backends that are known to glance. If there is only one (or
extreme care is taken by the operator and all users), Nova and Glance
collaborate for fast-and-light image-to-VM cloning behaviors. If there
is more than one, Nova does not handle the situation well, resulting
in silent slow-and-heavy behavior in the worst case, and a failed
instance boot failsafe condition in the best case. We can do better.
