Hi, I recently installed Fedora 16 in a Xen PV DomU and since I didn't
find a lot of information online, I wanted to share my procedure in case
it helps anyone else. My Dom0 is Debian Squeeze, which uses a kernel at
version 2.6.32.
The pygrub issues you described were fixed and I believe are now in
Xen 4.1.2.
F16 PV domU pygrub support patches are in xen-unstable, but not yet in
xen-4.1-testing.hg
Fedora's xen 4.1.2 rpms do have those pygrub patches included, though.

But that won't work for you since Debian is 4.0 I think.
I think they can be back-ported. Would you be up for trying to back-port
those patches and submit them to Debian Squeeze?
(Just search for M A Young and pygrub on this mailing list - he posted
the patches two months ago or so).
Because I deal with varying operating systems and because I prefer
fine-grained control over configuration, I don't use virt-* tools or GUI
front ends. I wanted to install the OS the regular way.
The basic install path was to use the live DVD to install in an HVM,
then switch to a PV with pygrub. I want to use pygrub so that I don't
have to copy kernels and init images around everytime the OS updates itself.
pygrub caused me some trouble because the version in my system can't
handle GPT partitions, grub2, or ext4 - all of which are used by default
in Fedora 16.
What follows isn't perfect, but should be useful for people who want to
install Fedora 16 in an environment similar to mine. Note that I'm
using x86_64 with VT-x, and that matters. Use your brain, and be
careful to recognize newlines that email may introduce.
