What is the hardware address for the virtio network device inside the
VM? The tap(4) device is host-side. I just tested this locally and am
able to have the guest-side vio(4) properly set:
vio0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:50:56:00:20:a5
index 1 priority 0 llprio 3
media: Ethernet autoselect
status: no carrier
If you want to change the host-side tap(4), see the ifconfig man page on
how to do so. vmd(8) could probably be changed to set that as well or
maybe there's a way to do it today that I'm not aware of. (I don't use
any of the lladdr features in vmd.)
