How to mount System.img file ?

Hi experts,
I am trying to mount LVM based System.img which is OEL6 file on Dom0 but it gave me following error.

procedure I followed
======================
lvm vgrename VolGroup00 VolGroupTmp1
LOOP_DEV_LVM=`losetup -f`                    &&
losetup $LOOP_DEV_LVM $1 -o106928640         &&
lvm pvscan                                   &&
lvm vgchange -ay                             &&
mkdir -p $ROOT_MNT                           &&
mount /dev/mapper/VolGroup00-LogVol00 $ROOT_MNT


[root@burexlj50u21 mapper]# mount /dev/mapper/VolGroup00-LogVol00 /test
mount: you must specify the filesystem type
[root@burexlj50u21 mapper]#

May I have procedure to mount it.
