<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I just set up a multi-node Grizzly release 2013.2 with 1 controller<br>
node, 1 network node and 1 compute node. I use GRE tunneling.<br>
<br>
I create one VM on the compute node and was not able to ssh to it using netns.<br>
<br>
One thing I noticed is that on my compute node, I do not have br-int<br>
and br-tun in the list, nor do I find any GRE tunnels. Am I supposed<br>
to create the GRE tunnels manually or they should be set up<br>
automatically by Quantum? Any idea or suggestion to make it work?<br>
<br>
Thanks in advance!<br>
