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!!!

I am not expecting PVOPS kernel to have Nvidia support in a foreseeable future.

Nope. What is the link?

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 ?

Boris.

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?
