That's a normal setting for all my controlled machines, desktop or laptop.

Yep!

Almost all my testing and debugging is done in virtual machines running on
either my desktop, my laptop, or one of my servers -- I don't pollute the
production environments that way, and it's easy to recover from problems when
they do happen.  I expect that even production servers in VM's is going to be
the wave of the future in not to long a time.  IBM's pushing it big time for
the power5 processor and there's almost as much advantage to doing it on intel
hardware as it is on a power5. Less physical boxes, but you need more power in
the boxes you do have..

> Why?

It doesn't have the full Intel/AMD instruction set and specifically the
instructions that make virtualization easier.
