Prior to Newton, the neutron-openvswitch-agent used 'ovs-ofctl'
of_interface driver by default. In Newton, 'of_interface'
defaults to 'native'. This mostly eliminates spawning ovs-ofctl
and improves performance a little.
upgrade:
- To retain the old default for neutron-openvswitch-agent, use
'of_interface = ovs-ofctl' in the '[ovs]' section of your
openvswitch agent configuration file.
- By default, the native interface will have the Ryu controller
listen on 127.0.0.1:6633. The listen address can be configured
with of_listen_address and of_listen_port options. Ensure that
the controller has permission to listen at the configured
address.
