Pasi,

Have you asked yourself a question why Fedora and Ubuntu always patch and package
Qemu-kvm-0.15(14)(13)(..).1.tar.gz , but not  Qemu-0.15(14)(13)(..).1.tar.gz ?
Just install a couple of src.rpms to take a look - what's inside.

Boris.

I've read the article and was surprised.

In that test, the KVM machine uses virtio disk and nic devices, while
the Xen machine uses the qemu emulated devices. Could that be the cause
for the poor performance?
