Is CentOS 5.5 your personal choice or business requirement ?

Hello, all.
I'm trying to setup Xen4 and pvops 2.6.32.x on CentOS 5.5. All the actions
were performed due to the guide on
http://ppadala.net/blog/2010/09/how-to-setup-xen4-pvops-2-6-32-x-on-centos-5-5/.

Xen 4.0.1 and kernel were compiled and installed according to the
instructions.
But when I'm trying to load the new kernel , the following output is seeing
on the screen:
Dom0 has maximum 16 VCPUs
(XEN) Scrubbing Free
RAM: ............................................................................................................................................................................................................................................................................................done.
And after that message the system is going to reboot.
My grub.conf entry for the new kernel is looking like this:
title Xen 4 + 2.6.32.25
root (hd0,0)
kernel /xen-4.0.gz dom0_mem=4096M loglvl=all guest_loglvl=all
module /vmlinuz-2.6.32.25 root=LABEL=/ ro nomodeset
module /initrd-2.6.32.25.img
The hardware I'm working on is IBM server 3850 M2 [71414RG].
After some googling I've found how to view Xen debug messages though serial
console.
After changing the grub.conf file to be as following and connecting to
serial:
title Xen 4 + 2.6.32.25
root (hd0,0)
kernel /xen-4.0.gz dom0_mem=4096M loglvl=all guest_loglvl=all
com1=38400,8n1 console=com1
module /vmlinuz-2.6.32.25 root=LABEL=/ ro console=hvc0
earlyprintk=xen nomodeset
module /initrd-2.6.32.25.img
The following output was received :

(See attached file: Xen-4.0.1.txt)

Thanks in advance.
