The bridge for nat seem to have only tap interfaces plugged, but not the real interface (ethX)

But the schema seem to say that dhcp is listening to bridge.

I'll try to play with libvirt on my local desktop, to see how it's work.

Or do they just use the bridge to setup the route for outgoing packets? If so, they still 
need to run dhcp on the tap device (because dhcp need to be in the same network).
