When I first installed the 7.1.0.16R beta it took a bit of digging to find out why I could not see my Amazon cloud instances in the cloud panel despite having the cloud providers being correctly configured. The console had a warning that my user account could not spawn the cloud widget.
The problem was that I needed to go to manage user groups > create a new user group for cloud users, or go to everyone > UI features > and enable Cloud Panel.
I think it would have saved me time if a dialog box appeared when the cloud widget errored out telling me that I don’t have permissions to view the Cloud Panel.
