This patch allows using the Quantum Ryu plugin. Ryu plugin lets Quantum link Open vSwitch and Ryu OpenFlow controller[1]. Ryu OpenFlow controller is not Openstack component, but I added some processing that is related with Ryu to stack.sh for the convenience of the person who intend to try the plugin. Instructions for using Ryu plugin: 1. Enable services: "q-svc", "q-agt", "q-dhcp", "q-l3", "quantum", "ryu" 2. Set Q_PLUGIN to "ryu" 3. Set an internal network interface name to connect br-int on plural hosts to RYU_INTERNAL_INTERFACE (optional) Example localrc: disable_service n-net enable_service q-svc q-agt q-dhcp q-l3 quantum ryu Q_PLUGIN=ryu RYU_INTERNAL_INTERFACE=eth1 [1] http://osrg.github.com/ryu/ Change-Id: Ic1da132fa421f1c70c10a319ee3239831b0f956f
