Prior to Newton, the default option for 'ovsdb_interface'
|
|
|
|
|
was 'vsctl'. In Newton 'ovsdb_interface' defaults to
|
|
|
|
|
'native'. This change switches the way of communication
|
|
|
|
|
with OVSDB from the ovs-vsctl tool to Open vSwitch python
|
|
|
|
|
api to improve out-of-the-box performance for typical
|
|
|
|
|
deployments.
|
|
|
|
|
upgrade:
|
|
|
|
|
- To keep the old default value use 'ovsdb_interface = vsctl'
|
|
|
|
|
in '[ovs]' section of openvswitch_agent.ini
|
|
|
|
|
(common path '/etc/neutron/plugins/ml2/openvswitch_agent.ini')
|
|
|
|
|
if there is a separate openvswitch agent configuration file;
|
|
|
|
|
otherwise apply changes mentioned above to ml2_conf.ini
|
|
|
|
|
(common path '/etc/neutron/plugins/ml2/ml2_conf.ini').

|
|
|
- The native interface configures ovsdb-server to listen for
|
|
|
|
|
connections on 127.0.0.1:6640 by default. The address can be
|
|
|
|
|
configured with the ovsdb_connection config option. Ensure that
|
|
|
|
|
ovsdb-server has permissions to listen on the configured address.
