qemu bridged networking

by paddyjackson

My final /etc/networking/interfaces file looks like (this is for Debian)

auto lo eth0 tap0 br0

iface lo inet loopback

iface br0 inet dhcp
bridge_ports eth0 tap0
bridge_maxwait 0

iface eth0 inet manual

iface tap0 inet manual
pre-up tunctl -b -u <my_user_name> -t tap0
pre-up ifconfig tap0 up
post-down tunctl -d tap0

I stole this from the following site joost.damad.be

Beware the username enttry above needs to be changed to your username… You will also need to install uml-utilities. Once I had this running I could start my image as follows:

qemu -net nic -net tap,ifname=tap0,script=no -hda debian.img
