Since the "No Image"/4 value never gets selected by end-users, the current PLM code would never return it.
Ideally, I think we would want to set a reload policy: My thoughts are that the reload policy might have the options to: * always power down after machine is used * only power down a vm if system is below a certain usage level * load, but hibernate/suspend the vm or node * load images based on a image priority or image weight (i.e. a weight of 0, would never get reloaded) Thoughts?
