Ok, If you just assign an image located anywhere on disk to a VM,
then OpenNebula does not know, that this is a persistent image.
But it is also strange, because when you start an VM with an
image located eg. in /scratch/, then this will be copied to
VM_DIR and the VM will be started with the copy there.
For the images repository you do not need much, just a folder
which is also on the shared storage (like VM_DIR) and available
also on the cluster nodes. Create a template and then use the
'oneimage register /path/to/template'. Then in the VM template
modify the DISK entry like this:
DISK = [ IMAGE = "<name_of_image>" ]
