# -- Background
The Neutron Linux Bridge plugin has removed from the tree in Juno. You must
migrate to ML2 using the script in: neutron/db/migration/migrate_to_ml2.py
# -- Agent configuration
- Edit the configuration file:
etc/neutron/plugins/linuxbridge/linuxbridge_conf.ini
- Copy neutron/plugins/linuxbridge/agent/linuxbridge_neutron_agent.py
and etc/neutron/plugins/linuxbridge/linuxbridge_conf.ini
to the compute node.
- Copy the neutron.conf file to the compute node
Note: debug and logging information should be updated in etc/neutron.conf
- On each compute node, the network_interface_mappings must be
configured in linuxbridge_conf.ini to map each physical network name
to the physical interface connecting the node to that physical
network. Entries are of the form
"<physical_network>:<physical_interface>". For example, one compute
node may use the following physical_inteface_mappings entries:
[LINUX_BRIDGE]
physical_interface_mappings = physnet1:eth1,physnet2:eth2,physnet3:eth3
while another might use:
[LINUX_BRIDGE]
physical_interface_mappings = physnet1:em3,physnet2:em2,physnet3:em1
$ Run the following:
python linuxbridge_neutron_agent.py --config-file neutron.conf
--config-file linuxbridge_conf.ini
Note that the the user running the agent must have sudo priviliges
to run various networking commands. Also, the agent can be
configured to use neutron-rootwrap, limiting what commands it can
run via sudo. See http://wiki.openstack.org/Packager/Rootwrap for
details on rootwrap.
As an alternative to coping the agent python file, if neutron is
installed on the compute node, the agent can be run as
bin/neutron-linuxbridge-agent.
