If I understand correctly, the idea behind these functions is: the application developers know there is a new QEMU event not known by libvirt library yet. And the developer still requests to add a callback for the new event without the upgrade of libvirt . The functions above provide a QEMU specific way to let the application register the callback by QEMU event without much intervention of libvirt. Then later if we want to promote the QEMU specific way to the libvirt, we should warn the application developer that the QEMU specific way is obsolete.
