Answering Henrik's question: We just want to see the results. If RHEL
native process, for example, 5000 TPS and RHEL+XCP process 4900, we
obviously will continue with a virtualized environment because the
difference is not significant to us.

Literature says that performance for guest is near-native, and that's
what I wanna test. And if somebody has already done this kind of test,
I could know what to expect.
