My personal opinion is that KVM has the greater momentum so over time I expect 
it to gain over Xen.  Today, KVM has for me one clear advantage: I can run it 
on my laptop without the need to run a hypervisor etc.

Today Xen is the more mature version and if you have critical workload on your 
servers, I advise Xen.  If you want to evaluate what virtualization to use in 
the future, consider kvm,
