I analyzed both XEN patches and determined where this patch must be done in KVM. It's just a matter of writing the code. Currently I'm studying for some final exams, so I will take some time off before I continue with this port. And because of hardware related problems, if it's not done in two or three weeks, then it will be finished in february.
