Thanks Fajar for your response.
DomU has this grub.conf
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,1)
# kernel /boot/vmlinuz-version ro root=/dev/sda2
# initrd /boot/initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,1)/boot/grub/splash.xpm.gz
title Red Hat Enterprise Linux AS (2.4.21-57.ELsmp)
root (hd0,1)
kernel /boot/vmlinuz-2.4.21-57.ELsmp ro root=/dev/sda2 1
initrd /boot/initrd-2.4.21-57.ELsmp.img
title Red Hat Enterprise Linux AS (2.4.21-57.EL)
root (hd0,1)
kernel /boot/vmlinuz-2.4.21-57.EL ro root=LABEL=/1
initrd /boot/initrd-2.4.21-57.EL.img
title Red Hat Enterprise Linux AS (2.4.21-53.ELsmp)
root (hd0,1)
kernel /boot/vmlinuz-2.4.21-53.ELsmp ro root=LABEL=/1
initrd /boot/initrd-2.4.21-53.ELsmp.img

... shortened.
On the guest OS, the actually devices are sda, and not hda.
[root@ignis log]# df -hl
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 9.7G 8.4G 817M 92% /
none 1004M 0 1004M 0% /dev/shm
/dev/sda1 12G 10G 1.1G 91% /mnt/rh9
/dev/sda5 112G 66G 40G 63% /disks/ignis1
Are you saying that the full virtualised loader (HVM?) cannot support sda?
Regarding the other command on the use of live CD/USB?
I don't quite follow the use on that.
The main objective I am trying to achieve is to flexibly transfer a running
service to run on a xen server,
in the hope that we do not need to redo a fresh installation and its layered
applications.
This will be useful so we can save time, but also some applications may not
easily be redone due to departure of staff who set them up.
If we use live CD/USB, can you tell how to transfer a running service to run as
a guest OS?
Many thanks again.
Kind regards,
Peter

at least this means boot and initrd was loaded.
What does domU's grub.conf look like? You might want to remove "quiet"
and "rhgb" (so you get more verbose messages). Also HVM domUs sees
disk as hda, not sda, so you need to change that (grub.conf, fstab).

I hope you use Live CD/USB for this? dd-ing the content of live disk
with mounted partitions (I assume sda is the disk you're booting from)
is a bad idea.
