Yeah, these are the problems you're going to hit with either toy
clusters or VMs. The main reason I like VMs for this is that it
eliminates a whole class of "futzing around with hardware" problems:
I might have to help dig people out of their holes occasionally, but
at least I don't need to go down to their labs and untangle a rats'
nest of cables.
I'm lucky enough to have a smallish and relatively good-humored use
community, so when someone really craters their test system, they
usually have a six-pack of my favorite beer on hand when they ask for
help. ;-) But that doesn't really scale...
