(Get the code!)
What we do over here is as follows:
we use a vlan based network setup where we create on management network which is allocated a specific segmentation_id (actual vlan).
Spinning up instances directly with only this network attached and configured with 2 security groups default + web.
we also configured an extra network without a subnet allocating to a specific segmentation_id. Since those networks don't have a layer 3 configuration openstack refuses to attach this network at instance creating. So I attach them using the nova attach-interface command as soon as the instance is launched, which works fine networking wise.
The missing subnets are probably causing this behavior?
