Hi,
vm1----eth0----localnet ----- externalnet------Internet

I have confidence this works. The logical network topology will look like
this:
externalnet externalnet1
| |
| |
| |
virtual router virtual router1
| |
| |
| |
tenant net tenant net1
| |
port port

You need to create two routers to use two external networks. Just declare
the external networks and do router-gateway-set.
Add each tenant network to their corresponding router.
>> vm1----eth0----localnet ----- externalnet------Internet
>> vm1----eth1---localnet ------ externalnet1 ----- Internet
This, however, does not work out of the box. I remember you can't create
two NIC from the same tenant network.
