Hi Dan,

I'm looking for the path of least resistance to add rbd support to https://github.com/CiscoSystems/openstack-installer/ Being unfamiliar with the data oriented approach it would be great to get your advice on the following.

* assume ceph has already been installed without cephx which simplifies configuration. From the point of view of integration tests it means installing when vagrant is setup ( which I currently rely on ) or via https://github.com/CiscoSystems/openstack-installer/tree/master/stack-builder. Not sure if the post_config is where it should be installed for test purposes. Not sure how to let it know what IP to use.

* create /etc/ceph/ceph.conf on each volume + compute node with the list of monitors IP. Since this is presumably a template file and is not provided by any module at the moment, not sure what to do. I could add this to cinder + nova because it's needed by both. I suppose it's what should be done since openstack-installer has no template at the moment.
