You can delete a snapshot any time. Deleting snapshots does not affect other snapshots or the current state of the virtual machine.
To delete snapshots
1. Choose VM > Snapshot > Snapshot Manager.
2. Select one or more snapshots.
3. Click Delete.
4. Click OK in the confirmation dialog box.
Note: You cannot delete the snapshot if the associated virtual machine is designated as a template for cloning. See Linked Clones and Access to the Parent Virtual Machine for a description of template settings for linked clones.
