Last time I looked at the Phoronix benchmarks, they were using the default
disk caching with Xen and Qemu, and these were not identical. From memory
KVM was using writethrough and Xen was using no caching.
This one says "Xen and KVM virtualization were setup through virt-manager".
I don't know whether that evens things out, as I don't use it.
