Thanks for responding Les.  You're a geyser of information.  I appreciate
you here and on the BackupPC list.

Anyway, I really don't want to go this way.  Out of all my servers, the
K12LTSP one is the one that winds up needing a reboot or troubleshooting
most often.  I seriously don't blame K12LTSP for this, I think it's just a
factor that it's basically being used as a 5-way workstation, so it's
subject to more vagueries of existence.  I also tend to install new stuff
on it more often, etc.  I often trade uptime for more features, etc. on
this box.

I want to virtualize mainly to save money.  I want to lower my power bill
and I've got vast quantities of unused clock cycles and storage space
being unused on computers that are spun up all the time.  My K12LTSP disk
is 10% full, while my web/mp3 server is 60%, etc.

I'll think more about what you're suggesting though.

But what are the license terms?  I can't find it anywhere.

Thanks again for the quick response.
