It was changed by https://github.com/openstack/nova/commit/33e3d4c6b9e0b11500fe47d861110be1c1981572 Now these attributes are not stored in instance snapshots, so there is no way to output them. Device name is most critical attribute. Because there is another one compatibility issue (see https://bugs.launchpad.net/nova/+bug/1370250): Nova isn't able to adjust attributes of volume being created at instance launch stage. For example in AWS we can change volume size and delete on termination flag of a device by set new values in parameters of run instance command. To identify the device in image block device mapping we use device name. For example: euca-run-instances ... -b /dev/vda=:100 runs an instance with vda device increased to 100 GB. Thus if we haven't device names in images, we haven't a chance to fix this compatibility problem.
