Is it possible to save a state of a vm in virtualbox, and from then always restart this vm by restoring the state ?
My problem, is that the state is deleted after restoration, and I can't restore it a second time.
In VirtualBox, there is a feature called Snapshot, which allows you to take a snapshot of the current state of the VM.
You can take a snapshot by going to
Machine -> Take Snapshot (Host + T) while the VM is running.
If the VM is suspended (machine state saved), you could go to the
Snapshots tab to take a snapshot.
From the Snapshots tab, one could also boot up a particular snapshot of the VM.
