Oracle VM Server is based on Xen. Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). If you choose this route, AWS makes it very easy to create servers (you just need a credit card) and learn how to use them.
