Hi Paolo, As you said, you will queue the v3 of KVM patch, but it looks like we are missing that part at the top of the kvm/queue tree. For your convenience, let me resend v4 so that we can upstream this feature in the next merged window. Also this patch series includes patches for qemu and kvm-unit-tests. Please help review.
