It's definitely an interesting tool, although not the first of its type on
the block. And the price is certainly right. :-) It allows you to run
multiple operating systems *simultaneously* on a single machine. Its
primary uses in the business world are reducing the hardware requirements of
test labs/training labs and allowing uber-geeks to bounce between a Linux
machine, Windows machine, etc. with just one physical computer. On the
server side, it allows consolidation and isolation of several applications
on a single physical machine, quick restores to a previous states, etc.
Unfortunately, programs like Virtual PC do NOT get around the problem that
DOS applications face when running on NT/2K/XP/Vista. The DOS programs were
written to communicate directly with hardware. This made it easy to send
perfectly timed dits and dahs to a serial/parallel port. Windows 95/98/ME
would still allow that because they were based on DOS. NT/2K/XP/Vista
intercept and referee all calls to the hardware. If anything, VPC adds yet
another layer of referees.

Subject: [CQ-Contest] Microsoft Virtual PC - multiple operating systems
I just stumbled across a reference to Microsoft Virtual PC,
a free program from Microsoft that supposedly allows the use
of multiple operating systems on one PC.
http://www.microsoft.com/windows/products/winfamily/virtualpc/default.mspx
Any thoughts on whether this would be suitable for running
DOS logging applications on an XP computer, or running
windows loggers under XP on a Vista computer?
There's probably a catch, because the computer
wonk/contesters out there should have tipped us off to this
by now.
