Hi, i already used persistent image setting, but why it didn't retain the changes made when the VM is shutdown? my VM was destroyed immediately after i shutdown it. So i used to suspend the VM rather than shutting down it.

Because of this, persistent Images can only be used by one VM at a time, while non-persistent ones can be used by several VMs. A persistent Image will have a faster deploying time (prolog phase), depending on your storage configuration [1]. For example, for the shared TM the deployment will be immediate [2], whereas for the shared TM the deployment time will be the same [3].
