Hi Naveen,
This is your configuration.
network_manager=nova.network.manager.VlanManager
public_interface=br100
vlan_interface=eth0
flat_network_bridge=br100
flat_interface=eth0

How many NICs do you have?
I have only one. If I had, it would have been much easier. I am doing similar things and encountered the similar problems. By modifying the stack.sh script. I made sure the configuration both on the two physical nodes is like:
network_manager=nova.network.manager.FlatDHCPManager
public_interface=eth0
vlan_interface=br100
flat_network_bridge=br100
flat_interface=br100

Then I can successfully launch the instances. However, VMs can only be pinged from the node where it is launched. If you want to ping or ssh them from outside, associate them with the floating ip. If you have two NICs, set flat_interface=eth1(the other NIC) will be fine.

Please let me know your latest progress on it.

Can you help with this problem?
