However, I can't push them until QEMU patch is pushed. This is sort of unwritten rule that we learned the hard way (we pushed libvirt patches that were written on the top of QEMU patches, but in the end QEMU patches that were pushed looked different and we had to adapt). I'll keep these in a local branch and push after QEMU patch.
