Hi, Unfortunately this is expected. If you take a snapshot you should not expect a clone but a RBD snapshot.
Please see this BP: https://blueprints.launchpad.net/nova/+spec/implement-rbd-snapshots-instead-of-qemu-snapshots A major part of the code is ready, however we missed nova-specs feature freeze so we haven’t proposed anything for Juno. So we will push something for Kilo.
