I haven't used Lustre but was also researching on using it for same purpose as shared storage for VMs. Dropped it in the end from consideration after some discussion on the Lustre mailing list points out that it's more intended for high performance rather than high availability. So it might not be that suitable as a HA solution.
Have you considered trying Gluster instead?
What do Gluster or Lustre offer that the builtin Red Hat Cluster Suite does not?
One does not need shared storage for Gluster. Each storage brick has its own storage, and Gluster handles replication/distribution across the nodes. Also, according to RH's site, RHCS is limited to 16 nodes. Gluster has no such limit.
