Red & Blue Pills

“You take the blue pill and the story ends. You wake in your bed and you believe whatever you want to believe.
You take the red pill and you stay in Wonderland and I show you how deep the rabbit-hole goes.” (c) The Matrix

You may hear the terms Red & Blue Pill being used lately when referring to Virtual Computing Environments. With the advent of the ‘hyper-visor’ and AMD/Intel virtualisation extensions on the processor it is becoming difficult to detect if a computer is running on virtual or physical hardware.

Blue Pill refers to running using emulated or virtual hardware.

Red Pill refers to having direct access to physical hardware.

Hyper-visor refers to a process that runs above the Operating System that controls the virtual machines access.

More specifically, Blue Pill also refers to a new breed of root-kits that exist above the operating system and are completely undetectable from the OS. Unless you need to use those virtualisation extensions on the new processors, I strongly suggest you leave them turned off.
