Guessing somewhat wildly, so don't take this too seriously: it seems tools like gpt sometimes try to find the real device for the partition you give. that might be happening you might use vnconfig to put that lvm partition onto vnd0 and then back up vnd0. This basically makes the guest's logical disk be the same in the host. I have done this when I had file-backed disks. (I am not claiming there isn't a bug - just that this might solve your problem for now.)
