On this post [1], Marko states: % Each NICs is logically attached to one and only one network stack % instance at a time, and it receives data from upper layers and feeds % the upper layers with mbufs in exactly the same manner as it does on % the standard kernel. It is the link layer that demultiplexes the % incoming traffic to the appropriate stack instance... As I understand it, there is only one vimage per interface. I'm surely wrong or the setup you described wouldn't be possible. Any explanation will be welcome :).
