The ml2 plugin uses mechanism drivers to determine which network segment and what VIF driver to use for a port. Mechanism drivers supporting the openvswitch, linuxbridge, and hyperv agents are added. The binding:host attribute is set on ports belonging to the dhcp and l3 agents so that they can be bound. To use with devstack until it is updated, set "Q_ML2_PLUGIN_MECHANISM_DRIVERS=openvswitch,linuxbridge" in localrc. The hyperv L2 agent does not currently implement the agents_db RPC, and will therefore not work with its ml2 mechanism driver. This issue will be tracked as a bug to be fixed in a separate merge. implements blueprint: ml2-portbinding Change-Id: Icb9c70d8b0d7fcb34b57adc760bb713b740e5dad
