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.)
that sounded promising, but seems to only work with file-based volumes.
jupiter# vndconfig vnd0 /dev/mapper/rvg0-builder9
vndconfig: /dev/rvnd0: VNDIOCSET: Operation not supported
Thanks anyway - I should take a closer look at LVM - I'm probably
scratching the surface too much here. But it was worth a try.
Kind regards
Matthias
