note that the guest never 'has' an interface, the
guests only 'have' IPs, and those IPs are used to
send packets according to the 'normal' network

separation you mentioned above .. what we know is
that it must be something only relevant in a local
(i.e. immediate) environment, as the MAC is lost
after the first routing
