Enable IP Forwarding in Dom0
echo 1 > /proc/sys/net/ipv4/ip_forward
and in /etc/sysctl.conf
you will find a variable net.ipv4.ip_forward=1
enable it or change value to 1.
Then in DomU's make sure the Gateway is your Dom0 i.e. for DomU your
Dom0 is behaving like gateway.
DNS will be same as the DNS on Dom0.Test if you have bridged network setup.
Check in your /etc/xen/xend-config.sxp
(network-script 'network-bridge netdev=eth1')
Should point to your default ethernet device and line is to be uncommented.
Similary check the entry
(vif-script vif-bridge)
It should be uncommented.

Have you configured IPTABLES or routing.
If yes then tell about the configuration a bit here.
