What is faster on the same hardware, Xen or KVM?
I'm trying to pick-up a virtualization technology to work, which gives the best performance.
There are some benchmarks here that I found on the subject: http://virt.kernelnewbies.org/XenVsKVM
They show KVM as a winner, with significant difference in performance - which goes against the idea that KVM is a type-2 hypervisor, and by definition it should be slower than Type-1 hypervisors (like Xen) - or at least that what the articles on the web say.
Any idea on the subject?
