Before you can start the neutron-server service and consume the Neutron API, a networking plugin must be defined. The remainder of this chapter is dedicated to providing instructions on installing and configuring the monolithic LinuxBridge and Open vSwitch networking plugins.

Note

Configuring Nova to use LinuxBridge

In order to properly connect instances to the network, Nova (Compute) must be aware that LinuxBridge is the networking plugin. The linuxnet_interface_driver...
