Hi,

If you are using a Ceph/RBD cluster then there are some things to take
into consideration:

- You need to have the ceph-common package installed in the system.

- The images are mounted using the kernel module, so you have to be
  careful with the features that are enabled in the images.

- If I'm not mistaken the RBD attach using the cinderclient extension
  will fail if you don't have the configuration and credentials file
  already in the system.

I can't help you on the network side, since I don't know anything about
Neutron.
