That's what I have. It's a little silly because in that mode nova
doesn't actually use any of the ips except to show them in the
dashboard. (More accurately, it doesn't insert any cloud config into the
instances, things like resizing instance's root disk to fit the flavor
specs don't work and you have to mount swap from rc.local...)

You can do
 nova boot ... --nic net-id=ID_OF_VMNET_ABOVE,v4-fixed-ip=X.X.X.209

I believe wherever you run nova daemons: openstack-nova-api,
openstack-nova-network, etc.
