So it stops being a virtual environment if you run Java or Python in it? (or anything else that uses bytecode?) Or if I get one of those old Rockwell Java processors (or a Dallas semiconductor Java iButton, or an ARM processor with a J in it) and make a coprocessor out of it (I dunno, plug it into the USB port and send code to it), I now have a virtual Java environment because the bytecode is running on real hardware?
