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
