Ok I have been able to proceed this part.So no need to worry about this one.
Here is how my grub.cfg looks like

menuentry 'Ubuntu, with Xen and  Linux' --class ubuntu
--class gnu-linux --class gnu --class os {
        insmod ext2
        set root='(hd0,8)'
        search --no-floppy --fs-uuid --set 6061f210-470f-401d-a29e-3c631fc04af4
        multiboot (hd0,8)/boot/xen.gz
        module  /boot/vmlinuz-
root=UUID=6061f210-470f-401d-a29e-3c631fc04af4 ro   quiet splash
        module  /boot/initrd.img-

and I was able to boot successfully but what I observed was
after I booted my wifi has stopped working.
PCI Id of wifi device 14e4:4315

Each time I try to install Broadcom STA driver(that is what was
working in non xen part)
 from Ubuntu 10.04 (64  bit) gui

System->Administration-->Hard Ware Drivers-->Broad Com STA driver I
get a failure message which says me to check
and here is the jockey.log
I had done
update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21 20
to have xend as service

I am not able to understand as how can I proceed
1) for the wireless part here.
2)  when I type xm info I get following error

xm info
Traceback (most recent call last):
  File "/usr/sbin/xm", line 5, in <module>
    from xen.xm import main
ImportError: No module named xen.xm
