Yes, those bindings will be enough for writing the image backend; you can take a look at what was merged into Cinder - https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/storpool.py - the create_cloned_volume() function at https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/storpool.py#L125 is pretty much exactly what the main part of the image backend driver will have to do.  Of course, if the Nova disk image is being cloned off a snapshot and not a volume, it will be even simpler - no temporary snapshot.","commit_id":"d4b1102b1f4a535658668383367fc0b5504ff98e"},{"author":{"_account_id":7677,"name":"Solly Ross","email":"sross@redhat.com","username":"sross"},"change_message_id":"44359f4b8a48bd6077aee5240cb193dadf11e5c8","unresolved":false,"context_lines":[{"line_number":47,"context_line":"Proposed change"},{"line_number":48,"context_line":"\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d"},{"line_number":49,"context_line":""},{"line_number":50,"context_line":"The proposed driver will make use of the StorPool API (based on JSON over HTTP)"},{"line_number":51,"context_line":"to create volumes in the StorPool cluster each time a new VM image is created"},{"line_number":52,"context_line":"and destroy them when the instance is terminated.
