Qemu doesn't handle that level of abstraction. The closest approximation
you could probably come up with is qemu-img's backing file support for
qcow2 images.
You should stick to using the rbd tool to create clones of rbd devices.
Alternatively, use a higher level tool (like openstack, etc) that
supports this.
