Actually thats a good question. What is a good way to benchmark virtual 
machines especially with regard to SMP.
There is unixbench, and nbench. But to my knowledge neither of those are 
really suited well for benchmarking SMP systems. I was thinking running 
distributed.net with one thread/cpu. I might run some unixbench tests 
just to see what kind of results I get.
Anyone else have a good benchmarking procedure that encompasses cpu, 
memory, and disk IO?
