Right, that's because libxl__device_nic_setdefault will set the bridge
field to xenbr0 if empty.
I'm not opposed to this behavior, seeing as we don't have much other
option I'm afraid. I guess we could open the tap interface in libxl
and pass it to QEMU, so that libxl can call the hotplug script knowing
the tap interface name, but that seems non-trivial.
IMO if we go that route it needs to be documented that NetBSD only
supports bridged mode for emulated HVM network interfaces for the time
being.
Thanks, Roger.
