IBM did level zero (under the OS) virtualization with the Series 360 back in the 1960s! This is nothing new. The Intel x86 architecture has always has the requisite number of "rings" to use, however those idiots over at Microsoft arrogantly wrote Windoze to use the wrong ring and preempt any chance of having VMs early on.

That's what happens when you get a bunch of script kiddies playing computer engineering instead of use REAL computer engineers like IBM.
