I realise that software like VMWare present their virtual devices as their own brand ('VMWare Network Adaptor' and alike), but isn't one of the points of virtualisation that the client doesn't know it's being run in a VM? At least I presume you could make the VM completely transparent, short of running timing tests on the virtual devices.
