IIRC the limitation is due to the OpenTap implementation of Windows itself. And thats probably a limitation inherited from elsewhere - the winpcap that Tap/win32 uses, if I understand correctly. Of course I can imagine one possibility. Basicially, use something akin to VDE: a master program is connected several instances of a modified qemu, so that qemu gets its ethernet packets from the master program and sends its own back to it. THe master program just does what vde_switch does: shuttle packets between the different qemu instances. Then you just need to get the master program to use winpcap or tap/win32 to be able to forward packets between the Windows host and the qemu guests. Nothing like that exists right now (at least nothing that I know of) for Windows - you will need to a) write it from scratch or b) port VDE to Windows. -- Infinite complexity begets infinite beauty. Infinite precision begets infinite perfection. _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
