We'll get there soon enough - there's no convenient way to support
encrypted qcow2 volumes backed by yet another encrypted volume without
fully and persistently managing node names via blockdev-add (yes, we've
been saying that for a long time, but qemu 2.9 will finally have
blockdev-add fully supported...)
