I am struggling to understand how to configure the host and guest.

I keep reading the vm man page, but it's not clear to me.  It said I 
should add an ip adx to my switch (public).  So here is the output from 
ifconfig on my host:

re0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 
mtu 1500
  options=82099<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE>

     ether 56:5f:80:13:f3:f6

     description: vmnet/freebsd13/0/public
     options=80000<LINKSTATE>
     ether 58:9c:fc:10:ff:bb
     groups: tap vm-port
     media: Ethernet autoselect
     status: active
     nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
     Opened by PID 76386

So my vm-public has adx 192.168.2.250

then I connect to the vm with: vm connect freebsd13

the bsdinstall is running, asking me if I want to install, want a shell, 
or live

I select shell, and invoke ifconfig.

But vtnet0 doesn't have an ip adx.  What am I doing wrong?
