People will reflexively see virtualization and figure it means noticeable hit in performance. Unfortunately many Windows users and developers are unaware their "Desktop" becomes a VM on Hyper-V installation. I see it all the time when people start arguing "type-1" vs "type-2" hypervisors. Usually if they have some experience with Xen comparing it to a Dom0 helps, but understandably people usually first compare it to VirtualBox because the process is opaque.
