The vast majority of guest benchmarking programs are going to give you 
invalid results.  The clock within QEMU (rdtsc and wall clock) are not 
very reliable and this is going to skew the results.

I suggest a benchmark that treats the guest as a server (something like 
specweb where the timing or thoroughput measurement is done on the host 
where time is reliable).
