I try to get a Nvidia Quadro PCI-E graphics card to work with xen in Dom0 with the binary nivida-drivers. I use the xen-2.0-testing tarball with kernel 2.6.12 and the nvidia driver package NVIDIA-Linux-x86-1.0-7676-pkg1. The nvidia kernel module compiles without errors but when I try to load it segfaults.
Is it possibly because the tls-libs are disabled?
Has anyone managed to get the nvidia drivers to work with xen? Or is there a general problem with xen + nvidia?

This is a recipe for disaster. The nVidia kernel driver has a binary layer that it not Xen-ready. It's very likely that it's going to be doing something it's not supposed to do in Xen.

You're out of luck until nVidia releases a Xen driver. You can also use the Open Source driver (or even just Vesa).

This is why binary modules are so evil...

Well, Nvidia seems to be interested in Xen support. On nvnews.net, I wrote a polite request for Xen support. Please see the thread at:

Unfortunately, due to major HW/SW upgrades, it'll be a short while before I can participate on the forum myself.

Often, vendors are accused of not showing interest in Linux, so since Nvidia has now shown Xen interest, I believe it'll be A Good Thing if some from this list would signup on nvnews and participate.

Kind regards,
