I don't imagine that if aws/ec2 is 'millions of customers' running on 'cheapest ethernet reference platform possible' they can do much fancy stuff with respect to virtual networking. I'd expect almost all of that to have to happen at the vm-host (not the guest), and that there's just some very simple encapsulation of traffic from the 'edge' to the vm-host and then 'native' (for some sense of that word) up to the 'vm'.
Because that’s what one of their engineers told me at one point in the past. Admittedly, it may have changed. My understanding was along the lines of a very large flat L2 space among the VM Hosts with minimal routing on the hosts and a whole lot of /32 routes. Again, my information may be incomplete, obsolete, or incorrect. Memories of bar conversations get fuzzy after 12+ months. Owen
