[one-users] virtual machine images

Hi,
If /data/one is the path of OpenNebula in all the hosts, then you
don't need the VM_DIR. In any case, you need VM_DIR to point to the
remote mount point of $ONE_LOCATION/var. So, if in the remote nodes
the /data/one folder is mounted in :

 - the same path, unset VM_DIR (comment it out) or set it to
VM_DIR=/data/one/var
 - other path (like /mnt/one) then set it to the var directory
(VM_DIR=/mnt/one/var)

Hope it helps,

-Tino
