Edit /etc/libvirt/qemu/networks/default.xml > > <network> > <name>default</name> > <uuid>...long uuid...</uuid> > <bridge name="br0" /> > <forward mode="route" dev="eth0"/> > </network> Why is this third step needed? Isn't it enough to simply add a network interface to the guest with br0 as source? (that's how I'm currently proceeding) e.g.: <interface type='bridge'> <mac address='yy:yy:yy:yy:yy:yy' /> <source bridge='br0' /> <model type='virtio' /> </interface>
