I want to add an additional network device to my bhyve virtual machine.

Great question — answering as the UphillTech team:

Check that the tap devices actually exist. When I was having this issue, apparently bhyve doesn't like it if the interface specific doesn't begin with tap so it has some kind of heuristic to auto-fail if it doesn't think it actually exists. 🤔 (I was trying to use a renamed tap0 as "Manager" and even though it was there it just wasn't being used)
