Comment 18 for bug 2051935

These are the settings I used for my ml2/ovs devstack:

Q_AGENT=openvswitch
Q_ML2_PLUGIN_MECHANISM_DRIVERS=openvswitch
Q_ML2_TENANT_NETWORK_TYPE=vxlan

enable_service q-agt
enable_service q-l3
enable_service q-dhcp
enable_service q-meta
disable_service ovn-controller
disable_service ovn-northd
disable_service ovs-vswitch
disable_service ovsdb-server
disable_service q-ovn-metadata-agent
enable_service placement
enable_service placement-api
enable_service placement-client

I am currently testing an additional nested router/network, will post the OSC commands when I'm done.
