Yes, it will work on the 3.0 kernel in experimental. It also works on
the Xen hypervisor in Sid, with some small modifications. Currently,
the package libxen-dev does not install any of the OCaml libraries
from the xen/tools/ocaml/libs source tree. The XenAPI is an OCaml
application and needs those libraries in order to compile. We also
need to include a few patches from upstream Xen; two of which allow
Xen to be compiled under the latest gcc 4.6 in Sid, and the other
fixes a problem that was preventing our toolstack from starting HVM
guests.

Yes, I can. I'm not familiar with the patch submission policy of this
list, so I hope it's okay that I've just attached all of the
aforementioned patches to this email. The patches are as follows.

- install-ocaml-libraries.patch

This must be applied directly to the xen-4.1.0/debian directory. It
modifies rules.real and libxen-dev.install such that the xen ocaml
libraries are built and installed.

- cset-23341-gcc-46.diff
- no-unused-but-set-variable.patch

These patches should be included in the xen-4.1.0/debian/patches
directory (and included in the series file). They allow xen to be
built on the latest gcc 4.6 in Sid.

- tools-libxc-fix-cpu-online.diff

This is a backport from Xen 4.1.1 which allows libxc (and our
toolstack) to start HVM guests. It must be included in the
xen-4.1.0/debian/patches directory (and included in the series file).

If you would like to follow along with our porting to Debian work, you
should take a look at our github repos. Jonathan Ludlam and I have
been working together on porting our libraries over to Debian, and
these should be good branches to checkout (his is probably more
complete than mine, so start there).

Thanks to everyone who is interested in this project and has offered
to help. Feel free to email me with any questions, or drop by #xen-api
on freenode to ask questions.
