I've gotten used to the idea of virtualization for all our other servers, where it is great to know we can mount the image on another host very quickly if a hardware problem brings down a machine, and it seems the same would be nice with Lustre...

We do virtualization routinely. Should be no issues. In fact, use of 
KVM/VMware/Virtual box for local testing is quite common among Lustre devs.

However, we really like to be close to the metal for performance 
reasons.  I would not use visualization in a production environment 
where performance was crucial.  I am also not certain how well 
high-performance networking does in a virtual server - we make heavy use 
of RDMA when available.
