Hi, all I am using 2.6.18-164.el5-xen kernel, Centos 5. And I am trying to get my Nvidia Card driver working on it. The driver I am using now is NVIDIA-Linux-x86-190.18.03-pkg1.run. I can get it running on 2.6.18-164.el5PAE kernel. I did as the some threads said, used "IGNORE_XEN_PRESENCE=y", reinstalled the driver, but still it's not working. Here is the message from dmesg: Oct 1 14:52:43 localhost kernel: NVRM: Systems with system memory mapped above the 4GB boundary Oct 1 14:52:43 localhost kernel: NVRM: are not supported when using x86 Xen kernels. Here is the message from xorg (II) LoadModule: "nvidia" (II) Loading /usr/lib/xorg/modules/drivers/nvidia_drv.so (II) Module nvidia: vendor="NVIDIA Corporation" compiled for 4.0.2, module version = 1.0.0 Module class: X.Org Video Driver (EE) NVIDIA: Failed to load the NVIDIA kernel module.
