Method 2

Create a 10 gig image file, Change this according to how much space customer is using (IE a little more then what is being used)

dd if=/dev/zero of=/root/migrationtesting.img bs=1M count=1 seek=10240

#format it
mkfs.ext3 migrationtesting.img

#Mount it
mkdir /root/migratingtesting
mount -o loop migratingtesting.img migratingtesting

#Copy the mounted files over from hyperVM and unmount afterward
cp -rp /home/xen/migrationtesting.vm/mnt/* /root/migratingtesting
umount /root/migratingtesting
