Well, as others have argued, this is probably worthless.
But there is a way to detect virtual machines under x86, see
http://invisiblethings.org/papers/redpill.html
But if you run qemu without direct instruction copying, it won't
work (and qemu will run slower), because qemu will correctly
emulate the unprivileged instructions.
