Open Stack

I have dedicated controller, compute and networking nodes running on
Ubuntu12.04 with Havana. The problem is on Neutron node, when I create a
router and attach a public and private network to it. I am using VLAN to
connect nodes.

The findings are
1. The tap and qr ports connected to br-int are always down.

2. It is similar to qg interface

3. However, the VMDATA between Networking and Compute nodes is up and
running.

I am running out of clue to correct this, any help is appreciated.
