Unless VM0 sends an ARP inquiring about the destination IP, VM1 dutifully replies with its MAC (all through the hypervisor's virtual switch), then VM0 stack forms a frame with VM1's MAC as destination. The frame, from VM0's point of view, goes out of its *virtual* NIC, and then gets L2-switched locally by the virtual switch without going out of any physical interface. -- Oleg Goldshmidt | p...@goldshmidt.org _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
