Proxmox 3.2 with 3-nodes cluster and ceph server: running openvz/containers possible?

Hi all,

I'm a noob on this subject, but is it possible to run openvz containers (not KVM!) stored on proxmox "ceph" powered nodes?
Maybe with Ceph File System (http://ceph.com/ceph-storage/file-system/) implementation?

Now I'm running the containers on the cluster from a separate NFS server (in DRBD setup), but that has low disk/IO performance.
Also this setup uses vzdump in "suspend" mode to make a container backup. The downtime for containers with many files is quite high (minutes).

Thanks!

Ruben
