Openstack Liberty: VMs created via vlan based internal network aren't able to ping each other

Hi, I have installed openstack liberty via packstack. I have Controller and Network node on same machine and rest machines are Computes. I'm able to launch VMs and provide external IP [flat network] via cirros image which is pingable to and from the VM. But when i create an internal network of 192.168.x.x subnet [obviously vlan based] it doesn't get IP via DHCP, and 2VMs launched with same network on separate computes, don't ping each other. Packets didn't even pass to respective compute from where i started pinging, let alone reached to compute in front and VM on it. However; if VMs are on same compute, then they are able to ping each other. Any idea what could be causing this? Is there anything that i should check and paste output, then let me do. I'll do that. Here is my neutron.conf: http://paste.openstack.org/show/616979/ And here is my ml2_conf.ini http://paste.openstack.org/show/616980/ Also; here is openvswitch_agent.ini http://paste.openstack.org/show/616981/

Please revert in case there is any other file or output we need to look at.

First off, you seem to lack an assignment of physnet2 to the physical interface neutron should use to put your traffic on.
