I'm testing out the managed storage to connect to ceph and I have a few questions:
* Would I be correct in assuming that the hosted engine VM needs connectivity to the
storage and not just the underlying hosts themselves? It seems like the cinderlib client
runs from the engine?
* Does the ceph config and keyring need to replicated onto each hypervisor/host?
* I have managed to do one block operation so far (i've created a volume which is
visible on the ceph side), but multiple other operations have failed and are
'running' in the engine task list. Is there any way I can increase debugging to
see whats happening?
