[Haitao Jiang <jianghaitao@xxxxxxxxx>]

I just set up a multi-node Grizzly release 2013.2 with 1 controller
node, 1 network node and 1 compute node. I use GRE tunneling.

I create one VM on the compute node and was not able to ssh to it using netns.

One thing I noticed is that on my compute node, I do not have br-int
and br-tun in the list, nor do I find any GRE tunnels. Am I supposed
to create the GRE tunnels manually or they should be set up
automatically by Quantum? Any idea or suggestion to make it work?

Thanks in advance!
