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).
