When you assign a user or group permissions, you pair the user or group with a role and
associate that pairing with an inventory object. A single user might have different roles
for different objects in the inventory. For example, if you have two resource pools in
your inventory, Pool A and Pool B, you might assign a particular user the Virtual
Machine User role on Pool A and the Read Only role on Pool B. This would allow that
user to power on virtual machines in Pool A, but not those in Pool B, although the user
would still be able to view the status of the virtual machines in Pool B.
