Re: [Xen-devel] Compiling nouveau open source nvidia graphics card drivers for Xen paravirt-operations domain 0 kernel

["Mr. Teo En Ming (Zhang Enming)" <enming.teo@xxxxxxxxxxxxxxx>]

Dear Boris,

You do not have to remove nvidia geforce video card from the PCI Express x16 slot at all. Just go to BIOS and set Primary Video Graphics Adaptor to Intel GMA 4500 IGD. When you boot up, just do a Xorg -configure and remove all sections in xorg.conf.new related to nvidia. Then copy xorg.conf.new to /etc/X11/xorg.conf and startx.

In Xen pv-ops dom 0 kernel, the kernel module that will be loaded for Intel GMA 4500 is the i915.ko kernel module.

  I  suspect pvops kernel to work OK due to presence of driver for Intel GMA 4500. Hence X-Server will come up properly.
  This story seems to be about presence of Intel Video Chip driver in the pvops kernel
and nothing else. So, with ASUS P5Q-E  i have to look for video card with driver already
implemented in 2.6.31-rc6.

Please, advise if i am wrong about that.

Boris.

OMG! OMG! OMG! I have solved the problem with Xorg X server (GUI) not previously working under Xen pv-ops dom 0 kernels.

Here is what I did:

A.	Booted computer using NVIDIA card

1.	nvidia-installer --uninstall

2.	yum groupremove "X Window System"

3.	yum groupinstall "X Window System"

4.	Xorg -configure

5.	mv /root/xorg.conf.new /etc/X11/xorg.conf-nv

6. 	Make sure xorg.conf-nv contains "Driver 'nv'"

7.	cd /etc/X11; ln -s xorg.conf-nv xorg.conf

8.	Check X server is started successfully

B.	Reboot computer using integrated Intel GMA 4500 graphics on Intel DQ45CB

1.	Xorg -configure

2.	vi /root/xorg.conf.new

3.	Remove all sections related to nv inside 
xorg.conf.new, leaving only intel

4.	cp /root/xorg.conf.new /etc/X11/xorg.conf-intel

5.	cd /etc/X11; ln -s xorg.conf-intel xorg.conf

6.	Start X server. This causes
 garbage GUI output.

7.	Add nomodeset kernel parameter to /boot/grub/grub.conf. Reboot again.

8.	Start X server. GNOME desktop environment appears. SUCCESS! No garbage GUI output!


The solution to getting X server (Graphical User Interface) work under a Xen paravirt-operations domain 0 kernel is not to use NVIDIA cards. Since it is clearly impossible to get official NVIDIA drivers and open source nouveau drivers to work with Jeremy Fitzhardinge's paravirt ops dom 0 kernels. And also Jeremy's git tree does not have nouveau sources either.

Hence,  instead of using NVIDIA graphics cards with Xen pv_ops dom 0 kernels, use Intel GMA 4500 to get graphical displays (I am using Intel Desktop Board DQ45CB). 

Congratulate me on my success!!!

All what i do on F11:-

# yum install vncserver

Then put in /etc/rc.local

export HOME=/root
vncserver :1 -geometry 1280x1024 -depth 16

Reboot Xen Host and connect remotely via vncviewer  , using local X-server and GDM on Xen Host. KDM fails to with Xen.

There was one feed from Ian Campbell regarding Nvidia support by pvops kernel,
followed by Jeremy Fitzhardinge notice. :(

 Do you remember that ?

Boris.
P.S. GeForce 8500 GT installed on my box.

I might give Driver "intel" a try in xorg.conf.. Let me reboot to Intel GMA4500 first.

Dear Boris,

Could you get X.org X server to work with Xen pv-ops dom 0 kernels 2.6..30-rc3 and 2.6.31-rc6 under Fedora 11 64-bit?

There is no nouveau driver for jeremy's dom 0 kernel. And when I tried to compiled nouveau against Jeremy's kernel, it would not work.

Although I could compile and install official nvidia drivers against Jeremy's kernel, X server will hang and freeze.

So I tried to use driver "nv" and "vesa" for X server when I booted Jeremy's kernel. But X still would not work and give me a backtrace.

All this is when I am using NVIDIA Geforce 8400 GS PCI Express x16.

If I switch over to using onboard integrated graphics Intel GMA 4500, is it supported under Jeremy Fitzhardinge's pvops dom 0 kernel? What driver can I use in xorg.conf?

Thank you.

Why would you expect them to take care of Xen pvops ?

Dear Pasi,

I have compiled ttm and nouveau successfully against the stock/vanilla 2.6.31-rc6 kernel WITHOUT Xen paravirt-ops Domain 0 patch.

So it seems that nouveau could not be compiled against Xen pv-ops dom 0 kernel and could not work with it.

Do I need to request nouveau and tungsten developers to make ttm and nouveau code Xen pvops dom 0 aware?
