[Openstack] Need help with network config on a basic setup

Hi All,

I need some help on bringing up my openstack setup. I am using the havana release.

Note:
 Please excuse me writing a very long email. The intention is to provide
 as much detail as possible so that its easier for the community members
 to suggest a solution.

I was able to create and bring up a guest instance on compute node. But,

The issue is:
I
 am not able to SSH (from either controller on compute1) to the guest 
and I am not able to ping to guest IP (192.168.0.2). What am I missing 
or doing wrong?


Setup details are:

- I am using two servers each having 2 NIC ports:
        1) controller (SL6.3)               - em1(10.192.206.247); em2(192.168.0.10)
        2) compute1 (RHEL 6.4 x64)  - eth0(10.192.207.152); eth1(192.168.0.11)

-
 em1 and eth0 are connected via a switch. This is the management network
 (hosts file has these IPs against controller/compute1 hostnames)

-
 em2 and eth1 are connected directly by a cable. For my experimental 
setup, I want this to be the data network (I guess its also called the 
public interface)


Config Details are:
