KVM Guest Network problem in Ubuntu 8.04

I am unable to connect on the network/internet on my Ubuntu 8.04 guest OS using static ip address. If I use dhcp it works. Both my host and guest OS is Ubuntu 8.04. Can anybody help me with this?

Thanks.

 

What are the outputs of

Code:

ifconfig

and

Code:

route -nee

on the guest when you use DHCP?
