The xen kernel and hypervisor don't understand power management.  If you 
think about it, it's a much more complex problem.  This means while with 
the bare kernel you might see the CPU frequency scaled down (on my 
machine from 2.9GHz to 1.6Ghz) this never happens with the Xen kernel. 
Hence more heat.
