This is a packaging bug. Distributions should not be breaking apart the neutron code.
See this similar RedHat bug: https://bugzilla.redhat.com/show_bug.cgi?id=1120332 They resolved it by putting all of the code into a python-neutron package. ** Bug watch added: Red Hat Bugzilla #1120332 https://bugzilla.redhat.com/show_bug.cgi?id=1120332 ** Changed in: neutron Status: In Progress => Opinion -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1352619 Title: Cisco plugin module become the neutron dependence Status in OpenStack Neutron (virtual network service): Opinion Bug description: In the former neutron db migration code. We don't have to install the cisco plugin module if user don't need it. But now, because of the latest merged py file https://github.com/openstack/neutron/blob/master/neutron/db/migration/alembic_migrations/versions/5446f2a45467_set_server_default.py import the cisco_constants(line 34), the user have to install it. Otherwise, it will raise a cisco module miss error. However, this is a neutron plugin, it should not be the neutron dependence. The error can be reproduced by runnig "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini current". Error information. [root@rhelhw ~]# neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini current INFO [alembic.migration] Context impl MySQLImpl.
