I will look into whether fully virtualized is an option for KVM. If not,
I probably won't worry as all "modern" operating systems support
paravirtualized setups.

I've got no way of knowing how to run tests on non-linux VMs. If anyone
can give advice on benchmarking non-Linux OS', I'd be grateful and will
give it a go.

Can you (or anyone) suggests tests to run beyond bonnie++ and a kernel
compile that would be "real-world" and useful benchmarks? I think one
test that will help would be to run tests concurrently on two VMs to see
if there is a difference in how Xen or KVM handle very random disk I/O.

PS - I will likely need a week or so to get these tests done.
