Please,view Marc response. Third file is certainly missing or doesn't match name in /boot/grub/menu.lst.

Sorry , Boris ,  the correct error message is :
------------------------------------------------------------------------------------------------

Note that there is error only in initrd !

What you expect to find on (hda0,0 ) instead of (hd0,0) ?

Hi All,
       I am not able to boot Xen .

My "/boot/grub/menu.lst"  has this entry

root            (hd0,0)

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>
proc            /proc           proc    defaults        0       0
/dev/sda1       /               ext3    defaults,errors=remount-ro 0       1
/dev/sda5       none            swap    sw              0       0
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto     0       0
-----------------------------------------------------------------------------------------------------
# cat /boot/grub/device.map
(hd0)   /dev/sda
(hd1)   /dev/sdb
