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!!!
