I would like to have more than one spec proposal for it and to try to achieve community consensus before the new year for what's the best way to go. Currently it seems that the approaches that will be proposed are: - ovn-like solution with vlan tag per port [5] - routed solution with port per VM as explained by Brenden Blanco [6] I'm hoping that we will arrive to something in between or perhaps more complete than either of those options.
