If the "id" field is missing from the options given to blockdev-add, just omit the BlockBackend and create the BlockDriverState tree alone. However, if "id" is missing, "node-name" must be specified; otherwise, the BDS tree would no longer be accessible. Many BDS options which are not parsed by bdrv_open() (like caching) cannot be specified for these BB-less BDS trees yet. A future patch will remove this limitation.
