Great news.
Expecting to see the patch soon.

Do you base your code over the kernel's paravirt_ops and Ingo's KVM
hypercall?
Jusy yesterday Yaniv Kamay & I have discovered some bugs in the
'kvm_hypercall' function. The cache_regs/decahce_regs were mixed up.
Also I added a x86_64 hypercall.h file.
Hope to commit it today or tomorrow.
