About access control

how to use the “Access” button for new users by created,the users only simply operate their cloud-vms,such as start,stop,remote control.I prompted message:
"VM Remote Access.Web Console -The web-based console is not available because the ‘Cockpit’ role is not enable."but i can’t found the ‘Cockpit’ role in the product features.
I have granted the “All VM and Instance Access Rules” and “Compute-Clouds-Instances” for a new users.

“Cockpit” is a Server Role (like Automation Engine) and is configured on the appliance level.


Thank very much for you reply.I have done.
