[ovirt-users] nul interface error when engine is creating ovirtmgmt bridge post-deployment

Hello again, I've been working on an automated solution that uses the API to add a host on first boot, the code checks out (or maybe it doesn't), however I can confirm that the ovirt engine works through adding all requirements of a host properly except when it gets to setting up the bridge on the new node. The following link contains the log lines from the engine.log file, I can confirm that if I go to the engine web interface, I see my two interfaces on the new node, em1 and em2 (this is a Dell R420 server), and I can click on the "Setup Host Networks" button. The proceeding dialog window gives me the ability to drag over the ovirtmgmt logical interface onto the active physical interface and once saved I can see the engine go to work on setting up the bridge without an issue. My understanding is that this is supposed to be an automated process (which is what i'm going for), might someone be able to help me understand why im seeing the error I am? Am I just missing something from the api standpo int that is supposed to tell the system which physical interface it needs to use for building the ovirtmgmt bridge on top of? One thing to note (it shouldn't matter I don't think) but the engine is behind a nat, communicating over a vpn to the new node. I have to nat traffic from the engine so the ip address seen is different than what was supplied to the ansible playbook, i'm not familiar with ansible nor the playbooks used to know if that will have adverse impacts such as i'm seeing in the logs.
