Xen and KVM are types of hypervisors, like virtualbox is, but they run 
on Linux hosts. To use them, you would need to install linux on the bare 
machine. This in turn requires a CPU that supports virtualization (which 
most CPUs made in the last few years do support).

If you can install CentOS 6, you can use KVM which is what I recommend.
