Virtual Machine Settings for Snapshots
In the virtual machine settings editor, you can disable snapshots and set the virtual machine to revert to a snapshot when you power off. The following sections describe these options.
VMware Workstation speed and response times are improved when snapshots are disabled. However, all changes made to a virtual machine are permanent and you cannot restore an earlier state.
To disable snapshots, go to VM > Settings > Options > Snapshots.
If no snapshots exist for the selected virtual machine, you can disable snapshot functionality by selecting Disable snapshots.
If one or more snapshots exist for the selected virtual machine, the Disable snapshots option is disabled. If you want to disable snapshot functionality, you must first delete all snapshots for the current virtual machine. Refer to Deleting Snapshots.
Revert to a Snapshot When Powering Off
To set the virtual machine to revert to a snapshot when you power off, go to VM > Settings > Options > Snapshots. You have the following options when you power off a virtual machine that has a snapshot:
Just power off powers off the virtual machine without any change to its snapshots. This is the default setting.
Revert to snapshot reverts to the virtual machine's parent snapshot, that is, the parent snapshot of the current You Are Here position. With this setting, a virtual machine always starts in the same state. Reverting to the snapshot discards changes. For example, an instructor may need to discard student answers for a computer lesson when a virtual machine is powered off at the end of class.
Take a new snapshot takes a new snapshot of the virtual machine state after it is powered off. This is useful to preserve milestones automatically. The snapshot is displayed in the snapshot manager. The name of this snapshot is the date and time the virtual machine was powered off. The description is "Automatic snapshot created when powering off."
Ask me asks what you want to do with a snapshot each time you power off.
