First create the bridge in NetBSD:

    ifconfig bridge0 create

Then add the physical interface to the bridge:

   brconfig bridge0 add <if> up

where <if> is your physical interface.

In order to have this persistent across reboots, do

   echo "create" > /etc/ifconfig.bridge0
   echo "!brconfig $int add <if> up" >> /etc/ifconfig.bridge0


In the guest config file add
"bridge=bridge0" in the vif line.
