Nope - this is not true: This version of qemu-img does *not* detect qcow2 images which life inside a LVM2 logical volume.
Without the patch, qemu-img detects a 'host_device' in this case, e.g. 'qemu-img snapshot -l ...' does not print anything.
With the patch applied 'qemu-img snapshot -f qcow2 -l ...' works fine.
