    Did you read the rest of it? Post 18 said they both worked well under high load with xen utilizing the cpu better, and kvm with better io.
    That seems to be a recurring theme. I'd imagine the problem with the cpu tests in kvm are down to it not passing through the host cpu and instead relying on the qemu sse2 baseline.
    Again, if you could find something recent that backed-up your findings that'd be great.
