may you tell me how you set up your vde network ? I downloaded vde,
installed it, bootet 2 qemus (on the same subnet) and tried to ping each
other... I does not work, but i can ping the host they run on using a
tap0 device, and see the who-has... arp stuff while running tcpdump on
tap0. So it would be very interesting how you configured your vde_switch
qemu setup for multiple machines on the same vde_switch.
thanks,
