I've noticed that the new release of Ubuntu 13.04 includes deployment capabilities for Openstack in an HA environment as well as integration of Ceph for volume and object storage. I can't yet find a good walkthrough for it. I'm assuming that this still applies: https://help.ubuntu.com/community/UbuntuCloudInfrastructure
But are there differences? How many network interfaces should each bare metal server that is in MAAS have?
I am currently using Mirantis' Fuel to deploy Openstack, but it does not yet support Ceph in its automated deployment, which is why I would like to try out Canonical's solution.
