Is server 2008 R2 an "option" for a VM OS when creating the VM. We have a list of installed OS does not match configured OS. At what stage in the VM do you "select" its OS? And what problems can arise if an admin accidentally selects the wrong OS? All our 64-bit Server 2008 R2 have been selected as windows 7 64-bit, so i was trying to understand the logic?
