Dear Amit Singh
The best way to do this is try to make it into an ISO image.
Then used the QEMU to boot the ISO. Please try the following
example
1. Create the following directoris called at /home
# mkdir /home/xencd
# mkdir /home/xencd/isobin
# mkdir /home/xencd/isobin/boot
# mkdir /home/xencd/isobin/boot/grub
2. Copy the grub files
# cp stage2_eltorito /home/xencd/isobin/boot/grub/
# cp menu.lst /home/xencd/isobin/boot/grub/
3. Copy the xen.gz and the domain0 kernel
# cp xen.gz-2.6.20-2925.9.fc7 /home/xencd/isobin/
# cp vmlinuz-2.6.20-2925.9.fc7xen /home/xencd/isobin/
# cp initrd-2.6.20-2925.9.fc7xen.img /home/xencd/isobin/
4. Edit the grub /home/xencd/isobin/boot/grub/menu.lst
with something like this
title XEN EXAMPLE ON BOOT CD
kernel (cd)/xen.gz-2.6.20-2925.9.fc7
module vmlinuz-2.6.20-2925.9.fc7xen
module initrd-2.6.20-2925.9.fc7xen.img
5. To compile into a boot cd, create bash script called
makexencd.sh in the /home/xencd directory!
(very important that it must resides in /home/xencd)
#!/bin/bash
BIN=boot/grub/stage2_eltorito
DIR=/home/xencd/isobin
mkisofs -pad -l -r -J -v -V "XEN EXAMPLE ON BOOT CD" -no-emul-boot
-no-bak -boot-load-size 4 -boot-info-table -b $BIN -hide-rr-moved
-o /home/xencd/xencdboot.iso $DIR
6. Run the makexencd.sh script and will get a bootable ISO
called /home/xencd/xencdboot.iso
# /home/xencd/makexencd.sh
7. To run it with QEMU (I recommend at least 512 meg)
# qemu -cdrom /home/xencd/xencdboot.iso -m 512
hope this example will work for you

Subject: [Xen-devel] Xen-Qemu
Hello all,
I have a goal to run Xen on Qemu (Basically qemu give an emulated platform as ARM in my case).
I have done some experiment for- Xen to run on qemu ( for i-386 platform)
There is a problem- on the run time we pass parameters such as:
shell# qemu -kernel xen-3.1.gz -initrd initrd-2.6.18-xen -hda disk.img -append "root= as per your root file system on disk.img"
there are much more option we can see qemu --help.
But to boot xen there are three entry in /boot/grub/grub.conf
title Fedora (2.6.20-2925.9.fc7xen)
root (hd0,1)
kernel /boot/xen.gz-2.6.20-2925.9.fc7
module /boot/vmlinuz-2.6.20-2925.9.fc7xen ro root=LABEL=/ rhgb quiet
module /boot/initrd-2.6.20-2925.9.fc7xen.img
But we can't pass module --in qemu , i am not sure if any one correct me??
I execute this:
qemu -m 128 -kernel xen-3.1.0.gz -initrd initrd-2.6.18-xen.img -hda disk.img -append "root=/dev/VolGroup00/LogVol00"
