If it were just a delay, networkd should still eventually recognize the
device as configured. Maybe some packets are going missing? We probably
need a network trace from within the guest.

Also probably interesting to know if 'sudo service networkd-resolved
restart' changes the state of things, or if the device remains
'configuring'.
