I have proceeded pretty much as in the manual * Created keypair and saved it * Added port 22 to security group

openstack security group rule create default --protocol tcp --dst-port 22:22 --remote-ip 0.0.0.0/0

• Created router with a public address
• Created network and subnetwork and connected it to the router
• Created instance connected to the subnetwork. It's an Ubuntu instance, 16.04, the default one.

However, I can't log in. Password does not seem to be set, and ssh using

ssh -i ~/.ssh/openstack-key.pem ubuntu@8.43.x.x -vvvv

just returns "connection refused". I don't know if ssh is not installed, by default, in this ubuntu image or I have to open some port somewhere, but I don't seem to find a way to do that.
