To add a new role:
- Go to Control Panel > Roles and Sets.
- Click the Roles tab.
- Press the "+" button or click the Create Role button at the bottom of the screen.
- On the screen that follows, give the role a name (label) and use the radio buttons to set its permissions.
- Click the Save button to finish.
On the Add New Role screen there are also buttons to give full access to the role (this automatically checks all relevant boxes to allow that role to perform any action) and to deselect all permissions, if you want to start from scratch.
Make sure to enable either the Select resources manually on virtual server creation or the Select instance package on virtual server creation permission, or both if required. If the user does not have any of these permissions enabled, they will not be able to create virtual servers.
