Colleagues,
I am experimenting with bhyve which uses tap(4) for network access.
I don't want to bridge tap0 with any of the hosts's real NICs. How can
I create a private network just between the host and the guest?
you are thinking too hard!
tap IS the interface..
ifconfig tap0 $address...
and in the VM, ifconfig vtnet0 ${some_other_address}
I even tried to create a lo1 interface on the host and bridge it with
tap0 but lo1 would not add as a bridge member even if I adjust its MTU.
root@vas:/etc # ifconfig bridge0 create
root@vas:/etc # ifconfig lo1 mtu 1500 up
root@vas:/etc # ifconfig bridge0 addm tap0
root@vas:/etc # ifconfig bridge0 addm lo1
ifconfig: BRDGADD lo1: Invalid argument
root@vas:/etc #
root@vas:/etc # ifconfig bridge0

Any help is appreciated.
