Yes, that was exactly the sort of thing I was looking for. It seems to
me that if the machine is alive and vmware is alive (as I beleive they
were) then it would be cool to tell vmplayer to reboot or shutdown
Windows gracefully so as to cause as little problems with the disk
image as possible.

I got anxious about 30-40 minutes after sending the original post to
the list and just issued a kill with no numeric value in top. vmware
closed immediately. When I restarted vmplayer Windows acted like it
does when you had to pull the plug on a physical box - complaining
that it wasn't shut down properly, etc., and went through it's checks.
The image came up fine and off it went to do some work.

Very nice thinking that since WinXP is just a disk file that I have
backed up on my network I can reload this machine in a couple of
minutes or even move it to another machine to run and not lose too
much time.

I didn't have as much luck with VirtualBox that didn't seem to like me
moving copies from one partition to another. I must go back and give
that another try as I'd like to be using Open Source but for now
VMWare is very nice.

Thanks for your responses.

Cheers,
Mark
