I'll continue some testing with the dir part (I thought LVM might be
more interesting to run into performance issues/.. ;))
one thing that I already noticed is that snapshot images are listed like
regular images:
$ pvesm list extsnapdir
Volid Format Type Size VMID
extsnapdir:555/snap-first-vm-555-disk-0.qcow2 qcow2 images 1073741824 555
extsnapdir:555/snap-second-vm-555-disk-0.qcow2 qcow2 images 1073741824 555
extsnapdir:555/vm-555-disk-0.qcow2 qcow2 images 1073741824 555
so we definitely still need to find a way to encode/store those which makes
the snapshot images properly separate from the "main" ones..
