Hi Carsten,<div><br></div><div>You are right, to save an image you have to shutdown the VM (i.e. shutdown + move the image back to the front-end). The image is "savedas" from there s if you cancel/delete a VM it is assumed that you do not want to keep the VM so it won't be saved. </div>
<div><br></div><div>The idea is to provide a fast image disposal mechanism for rapid VM provisioning. Basically VMs that do not need to preserve their state. </div><div><br></div><div>So basically, I think OpenNebula is behaving as expected....</div>
