[ubuntu-cloud] Fwd: UEC front node can not find the end node

[graziano obertelli]

Do you have the keys on the CC machine? If not, there is a good chance
that the CC didn't get register. You can check either on the webUI or
using euca_conf --list-clusters.

Once the CC gets register, you will see the node certificates in the keys
directory and you can sync them with the node.
