I have been asking on the qemu list how to get bridge network mode working under centos 4... To no avail. The following script is what I have tried as my /etc/qemu-ifup. It supposedly worked for fedora. #!/bin/sh # # qemu_up # # script to bring up the tun device in QEMU in bridged mode # # This script bridges eth0 and tap0. First take eth0 down, then bring it up with IP 0.0.0.0 # /sbin/ifdown eth0 /sbin/ifconfig eth0 0.0.0.0 up # # Bring up tap0 with IP 0.0.0.0, create bridge br0 and add interfaces eth0 and tap0 # /sbin/ifconfig tap0 0.0.0.0 promisc up /usr/sbin/brctl addbr br0 /usr/sbin/brctl addif br0 eth0 /usr/sbin/brctl addif br0 tap0 # # As we have only a single bridge and loops are not possible, turn spanning tree protocol off # /usr/sbin/brctl stp br0 off # # Bring up the bridge with IP 192.168.1.10 and add the default route # /sbin/ifconfig br0 192.168.1.10 up /sbin/route add default gw 192.168.1.1 #stop firewalls /sbin/service firestarter stop /sbin/service iptables stop Does anyone have qemu working in a bridged network mode and can share... I would appreciate it. When I boot my guest OS I do not get a DHCP address. Jerry
