-TODO
+Nova is able to write metadata to a special configuration drive that attaches
+to the server when it boots. The server can mount this drive and read files
+from it to get information that is normally available through the metadata
+service. For more details, see
+`Config Drive <https://docs.openstack.org/nova/latest/user/config-drive.html>`_.
