It's not necessary, but I figured I'd offer since Xen Summit is going on.
The part where it might be useful is the hypercall interface. I
basically exposed all the MSR configuration. I couldn't think of a
useful abstraction, and this way the full range of configuration is
available. Additionally, there are some convenience presets to make
it a little more user friendly.
Thank you for reviewing.

Jason
