Hi, Well... here it goes... I'm citing "by memory", but I'm confident I remember all the steps.
1 -> Get tun working. For this you have to load kernel module "tun.ko". If you have a standard kernel, probably it's already compiled and you just have to "modprobe tun" (as root). 2 -> Now, you have to configure a tun-based virtual netwrok on the host. QEMU does that for you. Just create a file "/etc/ifup-qemu" containing "/sbin/ifup $0 127.20.0.1" and "chmod 755 /sbin/ifup" 3 -> Then you may start QEMU (version 8.0, version 7.x doesn't work this way) with "qemu -net nic -net tap image-file.qemu" 4 -> After booting, you have to configure network on the client with "/sbin/ifconfig eth0 172.20.0.2" 5 -> And it's done... :-) Note: I'm assuming you're working as root. Device "/dev/tun" does not have write permission to "others"... to have root as a non-root user, you have to 1 -> Add the user to the suduers 2 -> Create a small script "qemu.sh" with (and chmod it 755) ------------------------------------------------------- #!/bin/bash # The next two lines are needed only if you want to # load the QEMU accelerating module #KQEMU_MOD=$HOME/Kernel-Modules/kqemu.ko #lsmod | fgrep -q kqemu || sudo insmod $KQEMU_MOD sudo chmod 666 /dev/net/tun qemu -net nic -net tap qemu-disk-image.img ------------------------------------------------------- 3 -> Change the file "/etc/qemu-ifup" to ------------------------------------------------------- #!/bin/bash sudo /sbin/ifup $0 127.20.0.1 ------------------------------------------------------- And it should work for a non-root user (if he's in sudoers). It's also possible to have it running for non-sudoers too, but it's a bit more tricky. I guess you don't need that... do you? Hope this helps. If you can't get it working, let me know.
