Please Help me.
---- 
 I followed the following procedure from the 
"Introduction to the Open Source Xen Hypervisor"
Zach Shepherd and Wenjin
taken from xen blog.
Install required packages
(e.g. apt-get install gawk libssl-dev libx11-dev gettext libncurses-dev
build-essential python-dev texlive-latex-base transfig tetex-extra
bcc bin86 pciutils-dev git-core curl texinfo libc6-dev mercurial
bridge-utils graphviz)
Download the latest Xen release
(e.g. hg clone 
http://xenbits.xen.org/xen-3.3-testing.hg)
Compile and Install
(e.g. make world; make install)
Create a ramdisk
(e.g depmod 2.6.18.8-xen;mkinitramfs -o /boot/initrd.img-2.6.18.8-xen
2.6.18.8-xen )
Configure the bootloader
(e.g update-grub)
Following are the entries in relevant files =>
-------------------------------------------------------------------------------------------------
# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
