Drivers for OpenStack Networking range from software bridges to full control of certain switching hardware. This guide focuses on the Open vSwitch driver. However, the theories presented here should be mostly applicable to other mechanisms, and the OpenStack Configuration Reference offers additional information. For specific OpenStack installation instructions to prepare for installation, see . If you followed the previous chapter to set up networking for your compute node using nova-network, this configuration overrides those settings.
