Open Stack

You don't need the admin keyring on a compute node but for tests it  
can help. Basically it depends on your ceph auth config which keyring  
you need on the openstack nodes.
If you already have ceph configured why don't you use it for all  
services? Of course live snapshots are not possible if your glance  
images are not within ceph (I don't think you mentioned that before).
