[one-users] Stop-Resume failing with shared storage

We are using shared storage as defined here

http://www.opennebula.org/doku.php?id=documentation:rel1.2:sm#samplea_shared_image_repository

When we run onevm stop or onevm suspend it tries to do SAVE_STOP and 
SAVE_SUSPEND and creates a checkpoint file on the host 
/var/lib/one/<vmid>/images/

and in the logs we see
 tm_mv.sh: Will not move, is not saving image

I think it is trying to move the checkpoint file back to the management 
node and based on logic in tm_mv.sh it is not moving.

Later when we try to do onevm resume , one picks a different host and 
tries to move the checkpoint file from the management node to the new 
host and again says "Will not move, is not saving image" and on the host 
it fails to bring the VM  since there is no checkpoint file on the new host.

How can we ask ONE to not resume from checkpoint file but instead load 
from the disk file that is in the template.
