several config options are in the DEFAULT section and shouldn't be

[Steven Dake]

Our default configuration file and quickstart guide set configuration options in the wrong places:

2015-05-03 17:08:16.690 1 WARNING oslo_config.cfg [-] Option "db_backend" from group "DEFAULT" is deprecated. Use option "backend" from group "database".
2015-05-03 17:18:52.263 1 WARNING oslo_config.cfg [-] Option "rabbit_host" from group "DEFAULT" is deprecated. Use option "rabbit_host" from group "oslo_messaging_rabbit".
2015-05-03 17:18:52.263 1 WARNING oslo_config.cfg [-] Option "rabbit_userid" from group "DEFAULT" is deprecated. Use option "rabbit_userid" from group "oslo_messaging_rabbit".
2015-05-03 17:18:52.264 1 WARNING oslo_config.cfg [-] Option "rabbit_password" from group "DEFAULT" is deprecated. Use option "rabbit_password" from group "oslo_messaging_rabbit".

We need to refresh the configuration file and change the quickstart guide (and possibly devstack integration) to store these config options in non-deprecated places.

Reason for medium is warnings confuse users and should be avoided.

Cannot see any reference to db_backend in the magnum repo.

Tom,

It comes from one of the oslo modules.

We need to replaced by [DEFAULT]/transport_url.
