There is a Xen vs. KVM in performance question on ServerFault.

What will be the performance difference if the choice is between Xen and OpenVZ?

How is it best to measure?

Some may say "you're comparing apples and oranges" but I have to choose one of the two and it needs to be wise choice. Performance is most important to us. We may switching to Xen from OpenVZ because Xen is more ubiquitous but only if performance difference is not significant. In January 2011 I'm thinking of doing a head to head performance comparison - here is my project proposal to our Bioinformatics facility director.
