bridge ports lo (kvm)

[thufir]

Want to use KVM, so setting up bridging.

current, using *wifi*:

thufir at dur:~$ 
thufir at dur:~$ cat /etc/network/interfaces 
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
thufir at dur:~$ 



http://xmodulo.com/use-kvm-command-line-debian-ubuntu.html

says to make it look like:


#auto eth0
#iface eth0 inet dhcp

auto br0
iface br0 inet dhcp
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
        bridge_maxwait 0



so I want like:

auto br0
iface lo inet loopback
	bridge ports ????????


what goes there?  "bridge ports lo"?  That looks suspect.  

pointers appreciated.



thanks,

Thufir
