these are the fresh result 

on domU ifconfig gives the following result:
xentestl:ifconfig
eth0    Link encap:Ethernet HWaddr 00:16:3E:5D:IF:3D     ****

**** the eth8 changed to eth0.

route -n on domU shows the following result:

dom0 ifconfig has the following result :

though i am able to ping between two domUs but cannot ping the gateway
i followed the instructions provided by you as well but still 
i am not able to ping the gateway from domU.
i also referred to this networking guide but could succeed
