Try to have a look at the boot from volume feature. Basically the disk<br>
base of your instance is an RBD volume from Ceph. Something will be<br>
remain in /var/lib/nova/instances but it's only the kvm xml file.<br>

> I'm sorry if this has been asked before. My question is: can I integrate ceph into openstack's nova & cinder in a way, that I don't need /var/lib/nova/instances anymore? I'd like to have EVERYTHING in ceph, starting from glance images to nova-disk-images and volumes (cinder). And more important: Can this be done in a way so that my horizon-users can still use horizon (including snapshotting) without the need of abusing the command-line? :)<br>

I haven't done it with Ceph but I've done this sort of thing using iSCSI mounts on the compute node.
