It's awfully hard to know what that means.  What is "playing games
with VM"?

Whether cloning is a good thing or not depends on the particular
hardware.  Is Linux saying that it is wrong to clone on Sparcs, since
on later Wintel architectures it will be wrong?  Perhaps cloning is
better in some cases, and copying is better in some cases, and that's

Admittedly, doing cloning correctly takes skill.  It's a shame that
those who had that skill are described as "incopetent idiots"
