SOLVED!
It was a kernel issue. The current Fedora 8 XEN kernel was the issue. Since
there was not a newer one available I enabled the development repo and
installed the Fedora 9 XEN kernel that was in it. A couple of small hacks
with the drive source and I have a working NVIDIA 169.07 driver. I assume
when the next kernel is release for Fedora 8 it will resolve this issue.
Was:
Code:
kernel-xen-2.6.21-2952.fc8
kernel-xen-devel-2.6.21-2952.fc8
Now:
Code:
kernel-xen-2.6.21.7-2892.fc9
kernel-xen-devel-2.6.21.7-2892.fc9

I was able to get it to compile and install no problem finally, but it locks
up when I startx. I can compile it for non-XEN 64bit no problem. The non-XEN
kernel is significantly newer (2.6.23 vs 2.6.21)

Same problem as what I am getting.
I am using the NVidia Geforce 8 series drivers for 64-bit.

The problem with video on Xen is that the driver needs to be Xen-aware.

Will the Xen patch for NVIDIA graphics drivers mentioned in the below
opensuse.org link work with Xen 3.4.1 rc and Jeremy's pv-ops dom 0 kernel
2.6.30-rc3 or 2.6.31-rc6 under Fedora 11 64-bit? Please see the patch code

No wonder compiling official NVidia drivers against the Xen domain 0
paravirt operations kernel doesn't work. It causes my X server to show a
blank screen and freeze. NVidia drivers need to be patched for it to work
with Xen kernels.

May I know where I can get the patch?

Dear All,
I can confirm that recompiling the Xen dom 0 paravirt-ops kernel using
gzip compression works. I can use the generated bzImage to boot up Domain 0.
If you attempt to compile the Xen Dom 0 pv-ops kernel using bzip2
compression, you won't be able to boot up Domain 0 using the generated
bzImage. You will get an ELF error and kernel panic on CPU 0.
As for X server, I haven't got much luck yet.
I was able to download and compile NVIDIA's kernel module directly from
official NVIDIA website for Fedora 11 Default shipping kernel. I was
able to start X server successfully and launch a desktop environment
using nvidia.ko.
However, if I want to compile the nvidia kernel module against Xen dom 0
pv_ops kernel sources, the kernel module compiles successfully, but when
I start X, the screen becomes blank and the whole system freezes there.
