Comment 5 for bug 1420996

Ok, in the meantime I can suggest a few things to try:
1. Try adding more rules with different ports, protocols, and IP ranges
2. Paste (using paste.c.c or paste.ubuntu.com links please, not directly here as it's very hard to follow) the output of these commands:
nova list-extensions
nova version-list
nova secgroup-list
nova secgroup-list-rules default
nova secgroup-list-rules juju-stg-pes-capomastro
nova secgroup-list-default-rules
3. If you have access via juju to that environment, you can try: juju set-env logging-config='juju=DEBUG' to enable debug logs.
Of course, drop any sensitive data before pasting.
