Open Stack

Hi John:

I don't think OpenStack supports an external DHCP server, because there's
no mechanism for OpenStack to determine which IP addresses have been
assigned to the instances. You could configure the OVS plugin in flat mode
for each of the two physical networks, but you wouldn't know what the IP
addresses were of the instances after they booted.
