RE: LPARS (was NT vs. AS/400)

VMWare is a virtual machine. It works as a software PC, I don't remember
which layer it works at, I believe it worked at the hardware layer, meaning
the OS has direct access to the hardware (but don't quote me on that). There
is an Open Source project that will work at the software level. Meaning the
software emulates the hardware, so I could run Windows 2000 on a Macintosh.
With VMWare you can have as many (depends only on RAM and CPU speed)
operating systems as you want running at a time. I had two linux releases
running in VMWare with Win2K as the "host" or primary with little to no
slowdown. I have a P2 350 with 384 MB of RAM. However it is quite expensive,
around $300 US, but it works pretty good, well work worth it for those that
test different operating systems for compatibility.

John,

VMWare is NOT a boot manager.  It is hard to explain adequately, but
your WinNT/2K or Linux box is booted, up and running.  Then you start
VMWare.  A window opens up and in that window, a BIOS boot takes place
followed by your OS of choice...all within that window.  Your other
stuff keeps on running.  2 separate OS's.

The Host OS (the primary) must be WinNT/2K or Linux.  The guest OS (the
one in the window) can be just about ANY Intel based OS.  Including
Win95/98/ME/NT/2K/XP, Various Linux flavors, BeOS, and many more.

Want to play with Linux?  But don't want to risk messing up your
current OS?  Load it into a virtual machine.  Do your Development under
Win2K but need to test under the various flavors of windows?  Load it
into a VM.

You all most need to try it to understand.  And they have a free trail
download.

Bob

Didn't OS/2 do that about 10 years ago?  I remember booting OS/2,
Win31,
etc.
With Boot manager?

Previous releases would be great for ISV's (which we are).  Instead of
having one machine at V5R1 beta, one at V4R5, V4R1, V3R7 etc, etc.  We
could have one machine with all of them.  And even better would be
FUTURE releases.  That way you could test the new release before
putting it on your production partition!

Actualy, this is something that WindowsNT/2K does TODAY!  Yep.  Check
out www.vmware.com .  On my production Windows 2000 box, I have virtual
machines for all the Windows flavors (Including XP Beta 2).  You
actually boot these VM's with a bios and everything.  Very Slick.
