journaling makes the image only unwritable, rather than both unreadable
and unwritable:
$ rbd create --size 1 --image-feature layering,exclusive-lock,journaling img
$ rbd snap create --no-progress img@snap

$ rbd clone --image-feature layering,exclusive-lock,journaling img@snap cloneimg
$ DEV=$(sudo rbd map img)
rbd: sysfs write failed
rbd: map failed: (6) No such device or address
[6]
$ DEV=$(sudo rbd map --read-only img)
$ blockdev --getro $DEV
