Managing Virtual Machines 182
Managing Snapshots
You can use Snapshot Manager to revert to a specific snapshot, as well as to manage the
snapshots. To open Snapshot Manager:
 Choose Snapshot Manager from the Virtual Machine menu, or
 Click the Snapshot Manager button
on the toolbar of the virtual machine window.
Note: To add this button in the toolbar, you should customize it. To learn how to do that,
refer to the Customizing Toolbar section.
Using Snapshot Manager, you can:
 create new snapshots and delete the unused ones
 view the snapshot tree of a particular virtual machine
 select a snapshot to revert to
 Note: You cannot create a snapshot manually or automatically or revert to a snapshot when
your virtual machine is paused.
The Virtual Machine Snapshots window consists of the following areas:
 The snapshots tree pane.
 The snapshots management pane.
Snapshots Tree Pane
Snapshot icons appear as screen shots of the guest OS window if the virtual machine was
running at the time you created a snapshot.
The left icon with a flag is the root of the snapshots tree - it is the initial state of the virtual
machine used as the reference point. You cannot delete the root icon. The root icon is visible if
at least one snapshot exists. If you want to delete a snapshot which is parental for some other
snapshots, you can decide whether to delete only this snapshot or delete it with all the
subsequent snapshots.
All snapshots in the snapshots tree are descendants of the root state of the virtual machine. The
first snapshot contains "differences" with respect to the root state. The second successive
snapshot contains differences with respect to the first snapshot. You may want to return to one
of the previous snapshots and work with it. If you then create a new snapshot, a new snapshots
branch will be created.
An icon that represents the current state of the virtual machine is marked by a red flag.
When you hover the pointer over an item, you will see a tooltip message with a short
description.
Snapshots Management Pane
The snapshots management pane includes the buttons necessary for managing the snapshots.
 The New button. Click this button to create a new snapshot for the present state of your
virtual machine.
