Unable to SSH an instance from controller node
Hi all,
I have a 3 nodes Openstack setup (2 compute nodes and 1 controller/network node). When I launch a new VM on the controller I am able to SSH it, while I am not able to SSH any VM on the compute nodes. Moreover: I am able to ping every VM, and I am also able to SSH a VM on compute node 2 from inside a VM on compute node 1. But whenever I try to SSH from the controller a VM on a compute node, the connection stucks at
debug1: SSH2_MSG_KEXINIT
Honestly I have no idea of where is the problem, I checked the network configuration lots of time and everything seems to be ok. I guess the problem is on the controller, but I have no hints apart from this.

Please, post
nova secgroup-list-rules default

Right now I don't have access to the deployment, I hope you can find the explaination sufficiently clear
What OS is running your VM ( why default name is andrea ) ?
How you created ssh keypair and assign it to VM upon creation ?
What was the the
nova boot ......
command ?It's ubuntu-server 14.04 (where I created the user andrea).
By the way, I tried also with a Fedora 20 Cloud Image and I got the same exact error.
Yes, I have created the keypair with
