[one-users] Save As and Detach option

[Javier Fontan]

Image ownership can be changed by the hypervisor (kvm) when it is
configured with "dynamic_ownership=1". Is that the case?

Are you using the same datastores for both tests, raw and qcow2?

Save as marks a disk to be saved AFTER shutdown. So that is the normal
way of working. In fact it will only be save if the VM is powered off
using SHUTDOWN or CANCEL but not DELETE.

The last test, when the image seems to ve saved but in fact it is not
there, seems a bit more problematic. Can you please dig a bit in
oned.log to check if there was something strange copying that file?

Cheers
