With SuSE kernels it's a bit fiddling needed to get a Debian guest running.
In general, you can run Suse, Fedora and Ubuntu as guests on Debian
quite fine with Debian kernels, but on SuSE and Fedora (OpenSuSE 10.2
and FC6 tested) running other distributions with their native Kernels is
a bit tricky - in fact, it works with SuSE once you found out how, with
Fedora I only got it working once to run Debian, but could never
reproduce it from scratch.

This kernel should match Debian's userspace tools best. Install this
kernel in your Debian guest, and run it either through pygrub(IIRC SuSE
has even anothe script to load Kernels from inside the guest filesystem,
but I have no SuSE at hand now) or copy it into /boot on the dom0 system
and configure your domains to use this Kernel and the matching initrd.

These should work, too, and I had success running Debian as guest on FC6
and OpenSuSE 10.2 with these.

But you don't have security support and updates on these kernels, if you
are interested in such things.

The Hypervisor interface is frozen since a while, and these should be
compatible.
