[PVE-User] Proxmox extended to support the Lustre high-performance filesystem

As a proof of concept (and just for the fun of it), we've implemented 
support for the high-performance filesystem, Lustre, in Proxmox at our 
institution.  A small demonstration of live migration with a Debian VM 
whose root filesystem is supported over a distributed lustre 
implementation can be found here:


This is a token implementation taken fresh off of our initial success in 
live migration over Lustre today.  Nonetheless, the changes to the 
Proxmox plumbing and the kernel tweaks required should have few problems 
porting over to our larger Proxmox clusters which support InfiniBand.

The point of our small proof-of-concept demonstrated in the above 
screencast was to see:
  - if it was do-able (we did it, so it is do-able)
  - if it was feasible (we tested it with benchmarks, and it's feasible)
  - if it is fully scalable to > 20Gbps Infiniband networks and multiple 
distributed Lustre metadata servers (yet to be carried out).

Comments, questions on the implementation, suggestions, and requests for 
particular benchmarks are welcome.
