Have you made changes in db models? There result should be: akamyshnikova@akamyshnikova:/opt/stack/neutron$ .tox/py27/bin/neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini revision -m 'test' --autogenerate Running revision for neutron ... No handlers could be found for logger "neutron.quota" INFO [alembic.runtime.migration] Context impl MySQLImpl. INFO [alembic.runtime.migration] Will assume non-transactional DDL. INFO [alembic.autogenerate.compare] Detected added column 'flavors.test' Generating /opt/stack/neutron/neutron/db/migration/alembic_migrations/versions/mitaka/expand/7a277e40970_test.py ... done OK
If this does not help make sure that all migrations applied, try to recreate database: drop it, run upgrade head and revision -m 'test' --autogenerate one more time.
