I set up Icehouse with a controller and a compute. Instances could be booted successfully, but I didn't create external network for instances. I used "ip netns exec qrouter-xxxxx" to access instances.

All images that I used were downloaded by Chapter 2. Get images, including cirros, ubuntu, fedora and centOS 6.5. I added keypair by following this.

I would like to ssh them by using keypair, but I always got the failed result, as follows.

I really couldn't figure out where the problem is and couldn't find any failed log. Is the problem on images? What should I do? Thanks.
