neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugin.ini upgrade head

That command needs to be run on an empty neutron database prior to starting neutron-server. This should be done in puppet like in upstream. When the database is empty when upgrade runs it sets up the version correctly. stamp is only needed when trying to run upgrade with existing tables.
