I used this tree:


Perhaps I should be using unstable, I don't know.  I would appreciate
recommendations.  My current goal (and I appreciate any input on this also)
is to use Xen 3.0 hypervisor and tools with the Dapperized 2.6.15 kernel. 
The alternative is to go with Xen unstable (3.1?) but that makes me a bit
nervous since I don't know how far along 3.1 is (that is, how unstable is it
in practice and when is it expected to be released).

Either way, the issue of which way to merge arises: is it better to merge
the Xen 2.6.16 changes back to the Dapper 2.6.15 kernel or merge the Dapper
changes forward to the Xen 2.6.16 kernel?  This is probably the single most
important issue.  I've been thinking that the former is a better strategy,
mostly because the Xen changes seem to be relatively small an inobtrusive
compared to the Dapper changes.

Since I wrote this message, I realized that I probably did the initial diff
backwards -- I posted the Dapper diff to an old Mercurial snap when I really
srhould be posting a Xen diff to the current Dapper git tree.

I'm building a dom0 kernel.

I have had some minor issues with Xend but mostly are n00b related.  For
example, I had to figure out that "xm create" won't autoload the loop
module.  But then again, I'm using Xend 3.0.1, not unstable.
