[sdk] specify mac address when creating ports with nova

When using connection.compute.create_server(), what is the structure of the networks parameter? I see in the example is a list of objects with a single key in the list being the uuid of the network. I know there are other parameters that could be in this list though. The os-migrate ansible playbooks add fixed_ip to this. fixed_ip is not a Network or a Port class parameter. Port has fixed_ips, but that would be a list. I want to add mac address to this port, but I'm not sure if that's possible or what key I would need to add. Is the structure of the networks object documented somewhere? Thanks --- John Ratliff Systems Automation Engineer GlobalNOC @ Indiana University
