Is this for HVM? AFAIK you can't really avoid doing a VMexit from HVM guest mode if you want to get back to Xen: Xen just doesn't exist in the address space of the guest. For PV guests, Xen is mapped into the address space so you basically just need to do a ring transition.

What use is a unicyle with no seat? And no pedals! Mark: To answer a question with a question: What use is a skateboard? Dave: Skateboards have wheels. Mark: My wheel has a wheel! _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
