9 | With snapshots, you can save a particular state of a virtual
|
---|
10 | machine for later use. At any later time, you can revert to that
|
---|
11 | state, even though you may have changed the VM considerably since
|
---|
12 | then. A snapshot of a virtual machine is thus similar to a machine
|
---|
13 | in Saved state, but there can be many of them, and these saved
|
---|
14 | states are preserved.
|
---|
15 | </p>
|
---|
16 | <p> To see the snapshots of a virtual machine, click the machine name in <ph
|
---|
17 | conkeyref="vbox-conkeyref-phrases/vbox-mgr"/>. In the machine tools menu for the VM, click
|
---|
18 | <b outputclass="bold">Snapshots</b>. The Snapshots tool is displayed. </p>

31 | If you select multiple VMs in the machine list, all snapshots are
|
---|
32 | listed for each VM.

33 | </p>
|

34 | <p>
|
---|
35 | Until you take a snapshot of the virtual machine, the list of
|
---|
36 | snapshots will be empty, except for the
|
---|
37 | <b outputclass="bold">Current State</b> item. This item
|
---|
38 | represents the current point in the lifetime of the virtual
|
---|
39 | machine.

42 | The Snapshots window includes a toolbar, enabling you to perform
