Hi Alex,
Thanks for pushing this forward! 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.
Regards,
Anthony Liguori
