In fact most of lustre developers use virtualized environments for  
testing and
whatnot. Some use xen for failover testing since it allows to easily  
attach
same "backend storage" to different virtual machines at the same time
when both are running (vmware does not allow that, I am not sure about  
vbox).

Well, it's the same as with non-virtualized machines mostly.
xen seems to work somewhat faster for me and some others since kernel- 
level
code is executed somewhat faster.
