  2. Add a new user:
    1. Add root or tty group to user
    2. The CIM only role (once applied) does override the administrator / root privileges
  3. Add a new permission:
    1. Add user or group to that permission
    2. Select the new CIM only role you created above

Enter the name for the CIM only role and check All Privileges > Host > CIM > CIM interaction, OK once complete to save the new role.


Please note, additional Virtual Machine interaction permissions are required to successfully run the VMware ESXi Virtual Machine Control Automated Task (which can power on, off, reset, suspend, reboot, shutdown or place the selected guest Operating System in standby) and these can also be added at this point.

These permissions can be added whilst setting up the user in the Add New Role dialog, or where the user already exists right-click on the username in Home, Administration, Roles and select Edit Role. In the dialog navigate to Virtual Machine > Interaction and check Power Off, Power On, Reset and Suspend saving changes once complete.
