Oh well, the vm fails to start with this template configuration. I am not sure how to fix it. There is only one vm running, so I don't think bhyve should be running out of slots/devices. There is no audio hardware in the bhyve host... is that a problem? I don't want to listen on the bhyve host, I want to ship the audio over the physical network to another FreeBSD system. Both the bhyve host and the target system are running FreeBSD 12/stable from the beginning of July.
