“Discover VCloud” option in Hypervisors/*nix/win for Autodiscovery jobs.

Hi folks,
Could someone help with getting as much as possible detailed information on what kind of information is discovered with “Discover VCloud” and relevant  checkboxes in Hypervisors/*nix/win for Autodiscovery jobs? It seems it's not fully documented yet

What shall be stated as a target?
Any screenshots?
Does it provide with information on cloud tenant resource pool usage?
