Comment 2 for bug 1012443

Obviously the external gateway needs to be configured to be in the correct vlan, etc on the managed switch/router, but it pretty much is as simple as the one line patch, updating the Nova DB to set the label (this gets used as the tag in dnsmasq and can be set during the network create), make sure nova-network doesn't collide with whatever addresses your physical network is using and then the custom configured dnsmasq.conf file.

Maybe one addition would be a parameter to nova-manage network create to specify that the network didn't need a nova gateway (something like '--no-gateway' on the create).

The last issue is I have no idea how any of this meshes with the long term, Quantum plans.

Thanks,

Nate
