Correct
Cool. I just got this in a personal reply, too:

At the time UML wasn't in the base kernel and it got very hard to maintain.
Ah. Makes sense.
A lot of people are very excited about Xen right now. Virtualisation
is a big
thing and you need the tools to do it well.
I'll say. It only just showed up in the dev tree recently and there's
an article in CRN about it already:

Not in the short term although getting to the stage where you do
"insmod virtualisation" is obviously desirable.
Now *that's* what I'm takin' about!
UML and Xen solve different problems. Xen is an extremely efficient
secure
virtualisation system, UML is a fantastic research, debugging and prototyping
system but is unlikely ever to be as efficient.
With my quick testing of the ttylinux sample, I can give this a big
nod. The first time I tried UML (on a dual 700MHz PIII), my initial
impression was, 'people actually find this usable?' It was terrible
performance-wise. I know it's probably come a long way, and it is
probably better suited on higher end machines, but as you say, it's
really meant for prototyping and the like, not deployment.

"Send patches"
Well, I'll have to learn python first, I suppose :-/
Its obviously a key part of the thing that you can provision Xen
guests
efficiently, manage them, update them and the like. Stateless linux obviously
helps there but anaconda on Xen guests > guest0 also has value.
Hmmm, interesting. I wasn't thinking stateless linux at the time, but
now that you mention it that sounds like a great idea.
