Hi guys, Ok, I''ve made the changes from prev V2 patch submission comments. Tested all the combinations. I am building xen patch just for the corresponding header file changes. Following that I''ll refresh xen tree, debug, test, and send patches. For linux kernel mailing list introduction, PVH is a PV guest that can run in an HVM container, uses native pagetables, uses callback vector, native IDT, and native syscalls. They were built on top of 89d0307af2b9957d59bfb2a86aaa57464ff921de commit. thanks, Mukesh
