When you run an action on a virtual machine, the host name is blank in the action dialog box.
When you select virtual machine on which to run an action, and click the Action button, the dialog box appears, but the Host column is empty.
Although your user role is configured to run action on the virtual machines, you do not have a user roll that provides you with access to the host. You can see the virtual machines and run actions on them, but you cannot see the host data for the virtual machines. vRealize Operations Manager cannot retrieve data that you do not have permission to access.
You can run the action, but you cannot see the host name in the action dialog boxes.
