The /etc/nova/nova.conf in the delorean repo now has deprecated options wrt rabbit, qpid and amqp in [DEFAULT], whereas new sections need to be added as per other projects i.e. [oslo_messaging_amqp], [oslo_messaging_qpid] and [oslo_messaging_rabbit]
This gives a lot of messages in syslog which we could do without
Also ...
When creating config file through tox, it doesn't generate the whole config correctly, as shown in the following pastebin
http://paste.openstack.org/show/213805/
It seems like that the tox config needs an extra parameter somewhere, unfortunately I don't know anything on this to resolve the problem
