Recognizing VM's vs. Physical

On our Satellite server, when viewing the Systems list, there are several icons that indicate servers as being "Non-virtual systems" that are actually VMs. As I understand it, there is a command or script that can be run in order to update the Systems list so that the server icon can quickly, visually allow VMs to be identified based on the icon.

Does anyone know what this command or script would be?

Thanks!
