This is an on-going problem confronting Xen users. Quite a bit of
blogging and wiki-authoring went into 2.0.7 and early versions of 3.
Search engines picked these up quickly and the blog/wiki authors never
updated the content.
There is newer information available on newer sites, the Xen lists
themselves, etc, however this list has to compete with many other wikis,
forums and blogs (not to mention list aggregators) in Google. So a
search has a 50/50 shot of turning up current information, depending on
the keywords entered.

All three of them run very nicely paravirtuailzed, with the exception of
CentOS 4 with 2.6.9. Is there some particular reason you need this older
kernel? It would do well as a HVM guest, the other two would do nicely
paravirtuailzed.
In my experience, Ubuntu is the simplest dom-0 OS to use and makes
things relatively painless. I have many Xen boxes in production, all
running one flavor or another of Ubuntu.

Try www.jailtime.org , those templates are easy to copy over and bend
into whatever you need. Just be sure to double check the yum sources
prior to updating or installing more packages.
The Debian template is also quite nice.

Check /etc/yum.conf, and remove the kernel.org repos from it. That will
fix your problem. The repos in repos.d should be the ones in use, remove
or comment out the ones found in yum.conf itself. I'm not sure why they
did it that way, but it needs to be undone.

Should be no need to do this. The dom-u kernel modules (found on dom-0
if you made a dom-u kernel) can just be copied into place easily.
