Thanks for quick reply Ross, please see the followings:
Please suggest me on how should I redo?

1. This is the result of /boot/grub/grub.conf:

default=0
timeout=5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu
title Xen-3.3 CentOS 5.2 x86_32 (2.6.18.8-xen)
        root (hd0,0)
        kernel /boot/xen-3.3.gz
        module /boot/vmlinuz-2.6.18.8-xen ro root=LABEL=/1 rhgb quiet
        module /boot/initrd-2.6.18.8-xen.img

Is this the xenlinux kernel from Xen.org? Why not stick with stock?


title CentOS (2.6.18-92.el5xen)
        root (hd0,0)
        kernel /boot/xen.gz-2.6.18-92.el5
module /boot/vmlinuz-2.6.18-92.el5xen ro root=LABEL=/1 rhgb quiet
        module /boot/initrd-2.6.18-92.el5xen.img

If this kernel boots you will see the issue you described.


title CentOS-base (2.6.18-92.el5)
        root (hd0,0)
        kernel /boot/vmlinuz-2.6.18-92.el5 ro root=LABEL=/1 rhgb quiet
        initrd /boot/initrd-2.6.18-92.el5.img


Can you give the output of rpm -qa "*xen*"

I guess with the appearence of xenlinux you downloaded the tarball and did a make install which makes reinstallation of Xen extremely difficult.

Next time use the src.rpm from 3.2 to build an rpm package which makes reinstalls a lot easier.

It is wholly possible that the Xen-libs package from CentOS was still installed when you did the make install and then was upgraded which wrote over your 3.3 libs with 3.1 libs.

I hope not but an rpm -qa will show us.
