Hopefully this will finally kill off qemu-kvm.git for good. I think this series is going to have to wait for 1.3 to open up. We have a very short release window for this release and I'd feel a lot more comfortable having such a significant feature spend some time in the development cycle getting testing/review. I'd like to see a few Reviewed-by's too for this series before it goes in. I expect they won't be hard to get but I also expect it will take a few more revisions of this series to get there.
