Comment 11 for bug 1153665

it's been a week since my last update but here is the final one:
I fixed this issue by rebuilding the cluster using the source files from Ubuntu's cloud archive repository instead of the COE sources. followed the same manual build procedure but with "Per Tenant Routers with Private Networks" in the Quantum configuration.

Quantum is configured with OVS + GRE with Tunneling.

VMs are getting Private Tenant IP addresses and after contacting the Metadata server running in my controller node they're also getting their private ssh keys injected. After associating/assigning floating IP address to the instances I'm also able to connect them from the public network.

Made a lots of good and positive progress... thank you for your inputs thus far.
