It is there in qemu-kvm and we suppose to bring knowledge from there :)

Hopefully just the good bits.

But I can drop it if you like.

I don't want to deviate unnecessarily from qemu-kvm so we can approach this in one of two ways. We can remove the guard in qemu-kvm and Avi can send me a pull request with this feature. I can also just pull in the patch as-is and we can fix this in both places later. I'm happy either way.
