So I re-install to re-test and I had this configuration
1. a maas server with eth0, eth1, eth2, where eth0 is the network MAAS is managing. This, by default was in fabric-2.
2. maas node with eth0, eth1, both NIC's were auto placed on fabric-0
On commissioning, I'd see the failure: AttributeError: 'NoneType' object has no attribute 'url' so, what I did is to ensure that eth0, the interface where I was managing DHCP was connected to fabric-0 instead of fabric-0. After I did that, the machine commissioned successfully.
Ok, so I think this relates to: https:/ /bugs.launchpad .net/maas/ +bug/1555570 as well.
