Networking not working on Packer created Ubuntu VirtualBox VM

Question

I'm trying to build a VirtualBox Ubuntu VM using Packer.

My image was successfully created and I configured it to use my Wi-Fi (Mac OS X AirPort) interface for bridged networking. However, after booting up the VM it only has the loopback interface set up.

Edit: here are more details on what's causing the problem:
