Problem creating VM using tutorial

Hi all,
I'm using this tutorial to create a VM ( http://www.howtoforge.com/virtualization-with-kvm-on-ubuntu-9.04 ) and I'm trying to do the LVM-based one. I tried configuring the bridge but I think that's where it's failing.. My VM is running but I cannot ping it..

A little more info : I have 2 IPs provided by my host, x.x.167.84 and x.x.167.85
My ifconfig looks like this :

Code:

I tried creating the VM on my x.x.167.85 IP so I can still use x.x.167.84 to access my host machine. The problem is it doesn't ping and I'm not experienced in virtual machines/bridging so I can't pinpoint the problem.

Can anybody help? Thanks a lot!

 

Can you post the outputs of

Code:

ifconfig

and

Code:

route -nee

on the host and the guest system?
