[Bug 1737684] [NEW] upgrading neutron appended faulty core_plugin option in neutron.conf

[Tobias Urdin]

Public bug reported:

Upgrading our neutron packages to Ocata, the following:

Using xenial ocata cloudarchive repo:
deb http://ubuntu-cloud.archive.canonical.com/ubuntu xenial-updates/ocata main

ii  neutron-common                      2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - common
ii  neutron-dhcp-agent                  2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - DHCP agent
ii  neutron-l3-agent                    2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - l3 agent
ii  neutron-linuxbridge-agent           2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - linuxbridge agent
ii  neutron-metadata-agent              2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - metadata agent
ii  neutron-plugin-ml2                  2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - ML2 plugin
ii  neutron-server                      2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - server
ii  python-neutron                      2:10.0.4-0ubuntu1~cloud0                   all          Neutron is a virtual network service for Openstack - Python library
ii  python-neutron-fwaas                1:9.0.1-0ubuntu1~cloud0                    all          Firewall-as-a-Service driver for OpenStack Neutron
ii  python-neutron-lib                  1.1.0-0ubuntu1~cloud0                      all          Neutron shared routines and utilities - Python 2.7
ii  python-neutronclient                1:6.0.0-0ubuntu1~cloud0                    all          client API library for Neutron - Python 2.7

What happend was that "core_plugin = openvswitch" was appended to
neutron.conf even though we have core_plugin = ml2 set.

Removed that line, restarted the agent and everything was fine again.
