Regarding that you can do with server create, I believe it's:

1. don't specify anything for networking, you get a port on the network 
available to you; if there are multiple networks, it's a failure and the 
user has to specify one.

2. specify a network, nova creates a port on that network

3. specify a port, nova uses that port and doesn't create anything in 
neutron

4. specify a network and fixed IP, nova creates a port on that network 
using that fixed IP.

It sounds like you want #3 or #4.
