Dear All,

I followed the XEN - NVIDIA - STEP BY STEP instructions at nV news forums but I still couldn't get X to work under Xen pv-ops domain 0 kernel. It still shows me a freezed blank screen. I couldn't switch to any tty (1 to 7 inclusive).

Here are the scenarios I have tried:
1) IGNORE_XEN_PRESENCE=y ./NVIDIA-Linux-x86_64-185.18.31-pkg2.run

2) IGNORE_XEN_PRESENCE=y CC="gcc -DNV_VMAP_4_PRESENT -DNV_SIGNAL_STRUCT_RLIM" ./NVIDIA-Linux-x86_64-185.18.31-pkg2.run

3)
./NVIDIA-Linux-x86_64-185.18.31-pkg2.run --extract-only
cd usr/src/nv

IGNORE_XEN_PRESENCE=y CC="gcc -DNV_VMAP_4_PRESENT -DNV_SIGNAL_STRUCT_RLIM" make SYSSRC=/usr/src/kernels/2.6.30-rc3-enming.teo-tip module

cp nvidia.ko /lib/modules/2.6.30-rc3-enming.teo-tip/kernel/drivers/video
cd /lib/modules/2.6.30-rc3-enming.teo-tip/kernel/drivers/video
depmod -a
rmmod nvidia
lsmod | grep nvidia
modprobe nvidia
lsmod | grep nvidia
None of the above three scenarios I have attempted worked for me.

When I tried to load the newly compiled nvidia driver (against the Xen Domain 0 paravirt operations kernel), it gives me the following message: NVRM: loading NVIDIA UNIX x86_64 Kernel Module 185.18.31 Tue Jul 28 17:52:27 PDT 2009

NVRM: PAT configuration unsupported, falling back to MTRRs.
Any more ideas?
