Digimer,
I would think the latest xen vs the latest kvm would be best. Fully virtualized vs Para-virtualized, is that possible with kvm? I don't believe your specs are too low end, they actually match pretty close to what I have and I don't think the OS matters that much as long as they are identical setups.
Thanks for offering to do the comparison, I am very interested in your results.

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.
