Because of the differences in Xen and non-Xen linux kernels the nvidia drivers as provided by nvidia don't compile against a Xen kernel. There is a patch availible at http://www.nvnews.net/vbulletin/showthread.php?t=77597 which should work with current nvidia drivers in portage now. On http://www.nvnews.net/vbulletin/showthread.php?t=81514 there is some information about SUSE users using this patch to use the nvidia drivers. I tried the patch against 1.0.9625 and manually compiled the driver. The driver compiled, but I had some instability issues of which I don't know whether they're caused by the driver or other problems in the system (also have to boot using noapic). If a xen flag could be added to the nvidia drivers ebuild which runs this patch (and perhaps sets environment variables in case they're needed as described on the second link) this shouldn't effect normal users.

Can you try 9746, which was just added to the tree? Likely, this will still need work, but I'm hoping.
I tried this patch on the 9631 and 9742 ebuilds. It compiles fine, but whilest merging I get: WARNING: //lib/modules/2.6.18-xen/video/nvidia.ko needs unknown symbol phys_to_machine Doing "modprobe nvidia" afterwards also gives me the "unknown symbol phys_to_machine" error. I also tried it with the 2.6.16.28-xen kernel from portage, but with the same results. Does someone know how to fix this?
Created attachment 122719 [details, diff] files/nvidia-drivers-100.14.09_xen.patch This is patch for x11-drivers/nvidia-drivers-100.14.09
Created attachment 124604 [details, diff] files/nvidia-drivers-100.14.11_xen.patch I removed the ability to enable pat with PREEMPT_RT and without XEN since it's not of great use and I was too lazy to add another iftest
The nvidia-drivers-100.14.09_xen.patch works for me with the latest xen-sources kernel (2.6.20-r2), but I still get the above error while inserting the module: "WARNING: //lib/modules/2.6.20-xen-r2/video/nvidia.ko needs unknown symbol phys_to_machine" Can anybody help me out with this issue, please? Thanks!
with 100.14.09 and applied patch i can boot fine. no symbol issues there. but when kdm starts i just get a black screen followed by an instant reboot. with 100.14.11 and applied patch the ebuild boils out with the following message: sh ./conftest.sh "x86_64-pc-linux-gnu-gcc" "x86_64-pc-linux-gnu-gcc" /usr/src/linux /usr/src/linux/_dom0 select_makefile full_output If you are using a Linux 2.4 kernel, please make sure you either have configured kernel sources matching your kernel or the correct set of kernel headers installed on your system.

NVIDIA themselves state that this driver does not work with Xen kernels since Xen kernels export a completely different API. Until NVIDIA changes their stance, Gentoo will not support Xen kernels.
I agree with Doug. As such, marking as WONTFIX.
I don't really agree with the decision to close the bug, as it seems to me to be only just some minor issues with the build-process. Nvidia doesn't official support xen, which I do understand, but anyway, the nvidia-Script listens to the env-Variable IGNORE_XEN_PRESENCE, and with the small changes I made to the xen-kernel, just to get the driver compiled, (http://forums.gentoo.org/viewtopic.php?p=4644365), my X11 runs stable and without any problems since last christmas... best regards, clemens
But anyhow, it is my belief that this bug belongs to xen-sources. that's where I filed a bugreport which got marked as duplicated. -clemens
