Odd.  I thought that vm-bhyve did that when the VM came up.

Hmm.  It looks like tap0 gets attached to vm-public if it is configured to 
attach to public.  Perhaps I just need to name the bridge that way.

But then I can't create the IP on the host until too late in the boot.  I 
assume that you mean to do that in rc.local.  Are you sure that the above is 
any different than what I did?

Hard to automate when VM can migrate to another host.
