Comment 18 for bug 627963

Carlos - thanks for looking into that! Cluster keys are only generated when --register-cluster is invoked. Trying to register an already registered cluster is supposed to be harmless, but turns out that it is not. (I just filed https://bugs.launchpad.net/eucalyptus/+bug/628328 for that.) I wonder if, upon reboot, UEC registration logic tries to re-register the cluster? If so, that may be the best solution. In the meantime, we'll look into why registration is not idempotent on our side.
