+  * networking - Network attachment and addressing configuration. Every key but ``addresses``
     is assumed to be a desired NIC on the VM. For each NIC stanza, the following fields are respected:
 
       * mac - A MAC address for the NIC

       * pci - A JSON object specifying ``slot`` and ``port`` specifying the PCI address for the NIC
       * attachment - What network from ``.networking`` is attached to this NIC
