The auditors VMware sent to us were just as bad. To ensure we weren't
running "rogue" ESX(i) servers or WorkStation, they made us provide full
arp/cam tables. Then a list of the virtual machines. "Oh look, this MAC
isn't listed as one of your virtual machines". It isn't because it was
running on virtual box or something like that. Auditor didn't know you
could export a virtual machine from VMware and load it into another
visualization software and it would keep the VMware MAC ....
