ploop is architectured in a way so images are not shared between containers.
More to say, base image is specifically checked to be unique (i.e. not 
used for
any other ploop device) because it is used to uniquely identify which 
container
it belongs to. I think this is the problem you have seen.

Nevertheless, you can use hardlinks to a "master" base image to create
multiple containers having the same base image. Note symlinks won't work,
you need hardlinks.

Hope that helps,
