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:
===/etc/xen/s1-0-2============================
name="s1-0-2"
memory=2048
kernel='/root/s1-0-2--vmlinuz'
ramdisk='/root/s1-0-2--initrd'
extra='root=/dev/xvda1 -- console=hvc0'
e820_host=1
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' ]
vnc=1
stdvga=1
==============================================
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 10.133.33.3/24 dev eth1
working on the DOMU console:
ip add add 10.133.33.3/24 dev eth0
ip route add default via 10.133.33.3 dev eth0
and then when back on DOM0 I do
ssh 10.133.33.3
I get a shell prompt on DOM0, whereas I would hope for a shell prompt on
DOMU.
