I too am looking for a Xen-aware nvidia module. It seems the guys/gals at rpm.livna.org have done some voodoo to support it in Fedora Core 6 at least. I haven't got Fedora Core 6 on my machines, but openSUSE, and I'll like to keep it that way -- Please officially support building the module on a Xenified kernel.

/Martin.

I got hold of a real interesting conversation last week with a guy that develop xen on cambridge (sorry I forgot to keep the text ) and a gamedeveloper regarding 3D support, pretty cool stuff switching between Windows and Linux online with full 3D rendering support...

P.S They were talking about the possibility, and IF you could do it and the stuff is not impossible... just damn complex... dont seem like anybodys there yet thought.

P.P.S Guess were in for a long wait!

Thumbs up Re: Nvidia support for Xen

Hi again folks.

Shortly after my posting last week I found this thread:
http://www.nvnews.net/vbulletin/show...light=Xen+9746

I have followed it with great success on my openSUSE 10.2 workstation, with a couple of modifications.

First, you need to get the patch from that thread:
http://www.nvnews.net/vbulletin/atta...5&d=1169773597

Then you need to get the 9746 version of the driver:
http://us.download.nvidia.com/XFree8...-9746-pkg2.run
http://us.download.nvidia.com/XFree8...-9746-pkg1.run

My version of the recipe:
Quote:
wget http://us.download.nvidia.com/XFree8...-9746-pkg2.run
sh NVIDIA-Linux-x86_64-1.0-9746-pkg2.run -x
cd NVIDIA-Linux-x86_64-1.0-9746-pkg2
cd /usr/src/nv
zcat ../../../../NVIDIA_xen-9746.patch.gz | patch -p4
ln -s Makefile.kbuild Makefile
+#+ Edit line 1288 from 'if 1' to 'if 0' +#+
make -f Makefile.kbuild SYSSRC=/usr/src/linux module
install -D -o root -g root -m 0644 nvidia.ko /lib/modules/$(uname -r)/video/nvidia.ko
depmod -a
modprobe nvidia
Make sure you have the kernel sources installed or something that will act like them. This seems to disable PAT support but does give quite good 3D support just the same. More than enough for Beryl and Compiz, at least.

Hopefully this will work for most people until nVidia officially supports Xen.

As for 3D accelleration in guests, I know it's possible with Linux Host and Linux guest via this:
http://www.cs.toronto.edu/~andreslc/xen-gl/

I had not heard of talks of 3D accelleration from a windows guest. That would be quite interesting

I know that VMware Fusion does 3D accelleration in Windows XP guests on the Mac, but only at DirectX 8.1 level and so far the don't support OpenGL in Windows, even though they map the DirectX calls the OpenGL on the Mac Host. This may still happen, though.

Interesting times indeed.

/Martin.

The truncation of the URL's make it hard to see, but the pkg2.run package is the x86_64 version and the pkg1.run package is the x86 version. Just in case anyone was wondering

Xen 3.2.0 is what we are looking for if we want 3D support it looks like... maybe betas late 2007...

Hey! Thanks for the post. I tried this method and it seems that everything compiles fine and the module seems to load. But when I made the trivial addition to my xorg.conf (Driver "nvidia"), I get an error when I execute startx:
Quote:
Failed to load module "nvidia" (module does no exist, 0)
Am I missing something? If it helps, I'm running gentoo...

Thanks in advance!

I have no problems following the instructions to compile the driver. However, what steps must be taken to enable direct rendering? I tried installing non compatible nvidia drivers and writing over the modules with the compiled ones; but that just resulted in segmentation faults in glxgears, etc.

It'd be great if someone could post a short blurb about how they managed to get direct rendering active (as many people are using distros like gentoo along with beryl/xgl under xen).

I don't know if this recipe works for the most people but it works fine for me. I'm using openSuse 10.2 x64 with the "Yast-provided" XEN-package (3.0.3).

I followed Martins description (this should be the last try) but it didn't work :-(

After compiling and installing the driver I received errors while starting xorg "module nvidia could not be loaded" something like that. Then I decided to try running the patched "nvidia-installer" after reboot to give it a last try, and *TADA* the nvidia logo appeared followed by the kde login screen.

Thanks a lot to all users and "hackers" working on that issue.

I hope that when the official Nvidia/Xen driver is released that it supports Xinerama correctly.
Not worried about 3D, but it would be nice bonus.
