Good.

Yep.

Also I think the "i386 Dom0" chapter is out of date.. it is not based on
the current patches.

"Status update" two weeks ago or so:
http://lists.xensource.com/archives/html/xen-devel/2008-11/msg00205.html

"The current dom0 kernel patches can boot up to a fully functional dom0
usersmode, and you can start xend to see that domain 0 is running. I *think*
in theory you can create a deviceless domain, but I haven't tried it. I'm
currently working on blktap support."

So maybe remove both the "i386 dom0" and "x86_64 Dom0" chapters and replace
them with something more up to date..

Yes, that's what I'm saying. Afaik "Scope" is based on earlier
work by redhat/fedora, and most of that information is now obsolete.

Jeremy Fitzhardinge of Xensource is now working on completing Xen pv_ops
dom0 support. Afaik it was started from the work done by redhat/fedora.

pv_ops dom0 patches posted to lkml by Jeremy Fitzhardinge:

Afaik it is totally upstream now.. ie. Xensource is doing this work, and
Fedora is just waiting for upstream (vanilla) Linux kernels to get this support
merged in..

Yep, it would be nice to get comments from others too.

And thanks to you for updating the page!
