Sorry I am back to work just now, yesterday was a holiday for us.

I have not yet got the machine back to test it.

Ok here I am listing down what you said,

Code:
1) Create an image file
===============
#dd if=/dev/zero of=/FAW/vms/linux_vm/disk2.img bs=1 count=1024 seek=500G

Code:
2)Create a loopback device for the file
===========================
#losetup -f /FAW/vms/linux_vm/disk2.img


# losetup -a
/dev/loop0: [fd01]:49160 (/FAW/vms/linux_vm/disk2.img)

Code:
3) Run pvcreate on the loopback device
===============================
# pvcreate /dev/loop0  (initialise disk created)
  Physical volume "/dev/loop0" successfully created

Code:
4)Run vgcreate on the "physical" volume
===============================
#vgcreate xen-vm /dev/loop0
Volume group "xen-vm" successfully created

Code:
5) Run lvcreate on the volume group
============================
#lvcreate -L450G -nxen_prov xen-vm

Logical volume "xen_prov" created

Code:
6)Create a filesystem on the logical volume
===================================
#mkfs.ext3 /dev/xen-vm/xen_prov
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
58982400 inodes, 117964800 blocks
5898240 blocks (5.00%) reserved for the super user
First data block=0
......................
.........................................

Code:
7) Mount the logical volume
========================
mount /dev/xen-vm/xen_prov /FAW/xen_vm

Let us know if this is rite, I have not yet executed the 7th point since I have not go the system back yet.
