Thanks, I applied all patches and pushed everything to icount on git://github.com/bonzini/qemu.git. I've also dropped Sebastian's "icount: Make icount_time_shift available everywhere" and adjusted his stuff to use cpu_icount_to_ns instead. I'm planning to send out patches 1/2/7 in my first 2.2 pull request, together with Sebastian's host clock alignment feature. The others will have to wait for the reverse execution patches which actually use it. Paolo
