Note Dom0 will also need to have an address like 68.210.25.1 that sits
on the internal network between dom0 and the domUs

(the HTML code wrapped the following line, which should be a single line:
mac=${mac:-$(awk 'BEGIN { printf "00:16:3e:%02x:%02x:%02x",
int(rand()*127),
int(rand()*255), int(rand()*255); }')}
Once you have the network-private set up, you will need to enable
forwarding and routing in dom0 and your desktop like normal.
on desktop
route add -net 68.210.25.0 netmask 255.255.255.0 gateway 192.168.0.130
on dom0
echo 1 > /proc/sys/net/ipv4/ip_forward
