I've got DOM0 and DOMU running (both Debian 7.3.0 AMD64), and can use
both individually and can `ssh localhost` on both with the expected
results.  I am setting up the networking by hand to understand how it
all goes.  The problem comes down to, no matter what I try, if I `ssh
w.x.y.z` on DOM0 in the hope of having a shell on DOMU, I always end up
with a shell on DOM0; the vif-bridge does not seem to carry the traffic
across and in to the DOMU.

Could someone describe the simplest setup which would achieve this,
using just the `xl`, `ip`, `brctl` and `iptables` commands please?

To be more concrete and provide maybe a starting point, here's a setup
I'm currently trying:


    extra='root=/dev/xvda1 -- console=hvc0'
    disk = [ 'phy:/dev/roots/s1-0-2,xvda,w' ]
    vif=[ 'mac=02:12:12:12:12:02,bridge=s1-0-2' ]
    vfb = [ 'type=vnc,vncdisplay=2' ]


And then on DOM0 (eth1 is a physical interface without a wire plugged
into it):

    echo 1 > /proc/sys/net/ipv4/ip_forward
    iptables -t nat -I POSTROUTING -j MASQUERADE
    brctl addbr s1-0-2
    brctl addif s1-0-2 eth1
    xl create /etc/xen/s1-0-2
    ip add add dev eth1

working on the DOMU console:

    ip add add dev eth0
    ip route add default via dev eth0

and then when back on DOM0 I do


I get a shell prompt on DOM0, whereas I would hope for a shell prompt on
