Sorry, what is " FlatDHCP Manager " ?

I haven't using nova-network for a while.

But from the help message for nova:

        nova help network-create

There is a parameter can set vlan_id:
        usage: nova network-create 
        ......
        -vlan <vlan id>
        ......

And for nova boot , there is a parameter related to the network:
        usage: nova boot 
        ......
        --nic <net-id=net-uuid,v4-fixed-ip=ip-addr,v6-fixed-ip=ip-addr,port-id=port-uuid>
        ......

I assume these commands should work for both nova-network and neutron.

Or, I misunderstood you ?

 Hi Chen,

 Do you mean 2 networks with FlatDHCP Manager? How can I tell which  network each VM will be on? Any documentation would be nice.

 Regards,

 George
