You need at least one physical network, let's say phynet1 which correspond
to a virtual bridge br-eth1.

You should connect at least one interface (eth1) on this bridge to be sure
that your virtual TAP will be able to communicate with the network.

Robert Kukura has written an excellent documentation [1] about how to
implement Open-vSwitch into Quantum.

In Essex, you should enable IP forwarding where you run nova-network with
the goal that VMs can ping outside.

In Folsom, you will find a L3 agent [2].
