[one-users] saveas not always working

[Ruben S. Montero]

Hi Carsten,

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.

The idea is to provide a fast image disposal mechanism for rapid VM
provisioning. Basically VMs that do not need to preserve their state.

So basically, I think OpenNebula is behaving as expected....

Cheers

Ruben
