Yes, I think so. I don't know if it is possible to expose that to an
HVM guest. You could ask on the Xen mailing lists.

You can convert an HVM guest to a PV guest although there is several
subtle steps (especially for XenServer/XCP guests) that I can't recall
off the top of my head, but If you ask on the Xen lists and Xen IRC
you will likely get some pointers.

Hope that helps.

Thanks,
