Looking at your diagram, the only connections from each vm to the
"outside world" are through a router or a br network device.  To me
this suggests a few possibilities:

	* The routers are forwarding the DHCP requests.

	* The br network devices are forwarding the DHCP requests.

	* There is an additional network device attached to one of
          your bridges, that is not shown.

Have you investigated each of these possibilities?
