The build script can be told to ignore Xen, I am running 177.80 on
2.6.27.3 (kernel.org + modified suse xen patches) with a single 9500GT
driving two 1920x1200 TFT's (not xinerama), I have a non xen kernel of
the same version installed so when I need to install nvidia drivers I
do the following:
rm /usr/src/linux
ln -s /usr/src/linux-2.6.27 /usr/src/linux
emerge nvidia-drivers #substitute the appropriate command for your distro
rm /usr/src/linux
ln -s /usr/src/linux-2.6.27-xen /usr/src/linux
cd /usr/src
sh /home/andy/Desktop/NVIDIA-Linux-x86_64-177.80-pkg2.run -x
cd NVIDIA-Linux-x86_64-177.80-pkg2/usr/src/nv/
IGNORE_XEN_PRESENCE=y SYSSRC=/usr/src/linux make module
IGNORE_XEN_PRESENCE=y SYSSRC=/usr/src/linux make install
modprobe nvidia
The drivers seem to work quite well under Xen, I can't really say they
are stable as my system occasionally locks up, but that happens
without the nvidia module/drivers loaded or X running at all and it
doesn't happen more frequently with them loaded so I think they are
probably ok.
