I did below steps.

 I pulled DOM 0 kernel from
git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
linux-2.6-xen

cd linux-2.6-xen

make clean

cp -a .config .config-old

wget -O .config
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.32.9-pvops-dom0-xen-stable-x86_64

make oldconfig

make bzImage

make modules

make modules_install

cp -a .config /boot/config-2.6.32.9

cp -a System.map /boot/System.map-2.6.32.9

cp -a arch/x86/boot/bzImage /boot/vmlinuz-2.6.32.9

and modified the grub.conf as below


Root(hd0,0)

 kernel /xen.gz console=vga,com1 com1=115200,8n1 msi=1 iommu=1

 module /vmlinuz-2.6.32.9 ro root=/dev/VolGroup01/LogVo100  rhgb quiet

 module /initrd-2.6.32.9.img

and rebooted the machine.  Then It booted with some xen messages and
stopped.  Those were the messages captured from serial console.

Please let me know if I did something wrong here.
