Normally, I'm a little reluctant to commit things to libvirt regarding
interaction with qemu if we don't at least have a qemu.git commit id;
but in this case, the patch to qemu came from an AMD person who knows
what he was doing, and qemu is very likely to take Boris' qemu
counterpart patch as written. Besides, we're far enough out from 1.0.1
that we can fix things if an unexpected change occurs on the qemu side
of things.
ACK series, safe to apply now.

Thanks, I've pushed the series. I will be monitoring the qemu-devel
mailing list for acceptance of the patches.
