According to Wikipedia...

1. The "master" OS must be aware of Xen.

2. Originally all guest OSes had to be aware too, but Xen now supports 
running unmodified OSes as guests as well.

You know, that's one of the things I dislike about Linux. Knowlege gets 
out of date in like 3 months. :-)

I saw a writing somewhere that said something like "using Windows is 
like living in a cheap hotel", whereas "using Linux is like living in a 
half-built cathederal being designed by seventeen architects. Every few 
weeks you wake up and think 'hmm, that stairway wasn't there before'..."

Oh, absolutely, I don't dispute that.  I have done that type of work 
myself.  It is possible to "break out" of a VMware jail (at least without 
VT, and some say even with VT it can be done because of the host/guest 
interfaces that VMware makes available), but you've got to write 
specifically to it.

It used to be that way a month ago, Darren - now knowledge is outdated in 
2 months.  Keep up at the back, will ya? ;-)

But then there are 15 people there to tell you that stairway *was* there, 
but you weren't. ;-)

And if you walk up the staircase, you'll fall from the 3rd 'floor' because 
the door's still a work-in-progress.

actually, if you are really bleeding edge, you'll fall because someone 
moved the staircase without telling you ;-)

I disagree, since the situation has been what Andrew mentioned for at 
least a year.

Yeah, cause like nothing has changed in the last year, since they 
modified Xen to run other operating systems.

It was kind of funny. When I read about Xen, I had the same sort of 
feeling as when I saw the first Macintosh.

Me: "Wow, cool. You can have multiple windows open at the same time!"
Salesman: "Yep!"
Me: "So how many programs can it run at once."
Salesman: "Oh, just one. But with multiple windows!"

Me: "Wow, cool. You can run multiple operating systems at the same time!"
Me, 10 minutes later: "Oh, as long as they're all Linux."
