Perhaps I forgot to reference the "ps - illegal instruction" thread in
my original thread - my apologies.
Nested virtualization is *not* the point or objective of the exercise -
enabling installation of Debian in W7VPC *is*.
Hypervisor is a very common "exception" in my experience - I guess it
depends on what you're exposed to in the workplace.
