  for people new to virtualization, i was simply suggesting that that
wording still leaves some doubt as to what's possible.

  what about a slightly longer explanation which describes what you
can support based on the capabilities of your system, as in:

  1) if your system supports H/W virtualization, you can do the
following:

     ... list of things ...

  2) if your system does *not* support H/W virtualization, you are
limited to the following:

     ... much shorter list ...

  that should be written for the newbie since the most frustrating
experience for beginners is to invest considerable time trying to do
something, only to eventually learn that it wasn't possible all along.

  i'm thinking a page entitled something like "So, you have a computer
and you want to get into virtualization."  does such a page exist?
