Hello,

Suppose I have two different kinds of CPUs which have exactly the same configuration except one supports VT-X while the other does not. If I want to test the I/O performance (or other perf. testing which is not particularly related to I/O) of the both domain0 and Para-Virtualized Guest Domain (HVM domain is not considered), shall I expect to get the same performance results on these two CPUs?

Thanks,

Liang
