Hi, I'm having trouble benchmarking disk i/o in my vm's. The data I get seems bogus.
have you tried perf top, you can see their other performance statistics there. there is more going on during a disk write than writing what your guests want. I think there is hardware passthrough for disks also.
At the moment I'm not interested in the benchmarks themselves but the reason why they show such an odd behavior. The fact that there might be "more going on" doesn't account for the results I'm seeing.
