| 7 | <p>You can create a full copy or a linked copy of an existing VM. This copy is called a <i>clone</i>. You might use
|
|---|
| 8 | a cloned VM to experiment with a VM configuration, to test different guest OS levels, or to back up a VM. </p>
|
|---|
| 9 | <p>The <b outputclass="bold">Clone Virtual Machine</b> wizard guides you through the cloning process. </p>
|
|---|
| 10 | <p>You can start the Clone Virtual Machine wizard in one of the following ways: </p>
|
|---|
| 11 | <ul>
|
|---|
| 12 | <li>
|
|---|
| 13 | <p>Click the VM name in the machine list and then select <b outputclass="bold">Clone</b> from the <b
|
|---|
| 14 | outputclass="bold">Machine</b> menu. </p>
|
|---|
| 15 | </li>
|
|---|
| 16 | <li>
|
|---|
| 17 | <p>Click <b outputclass="bold">Clone</b> in the <b outputclass="bold">Snapshots</b> window for the selected VM. </p>
|
|---|
| 18 | </li>
|
|---|
| 19 | </ul>
|
|---|
| 20 | <note>
|
|---|
| 21 | <p>The <b outputclass="bold">Clone</b> menu item is disabled while a virtual machine is running. </p>
|
|---|
| 22 | </note>
|
|---|
| 23 | <p>The <b outputclass="bold">New Machine Name and Path</b> page is displayed. </p>

| 35 | <p>The following clone options are available: </p>

|

| 38 | <p><b outputclass="bold">Name:</b> A name for the cloned

| 40 | </p>
|
|---|
| 41 | </li>
|
|---|
| 42 | <li>
|
|---|
| 43 | <p><b outputclass="bold">Path:</b> Choose a location for
|
|---|
| 44 | the cloned virtual machine, otherwise <ph conkeyref="vbox-conkeyref-phrases/product-name"/> uses the

|

| 49 | <p><b outputclass="bold">MAC Address Policy:</b> Specifies
|

| 50 | whether to retain network card MAC addresses when cloning the
|
|---|
| 51 | VM.
|
|---|
| 52 | </p>
|
|---|
| 53 | <p>
|
|---|
| 54 | For example, the <b outputclass="bold">Generate New MAC
|
|---|
| 55 | Addresses For All Network Adapters</b> value assigns a
|
|---|
| 56 | new MAC address to each network card during cloning. This is
|
|---|
| 57 | the default setting. This is the best option when both the
|
|---|
| 58 | source VM and the cloned VM must operate on the same network.
|
|---|
| 59 | Other values enable you to retain the existing MAC addresses
|
|---|
| 60 | in the cloned VM.

| 141 | <p>
|

| 142 | The duration of the clone operation depends on the size and number

| 144 | all the differencing disk images of a snapshot.

|

| 147 | You can also use the <userinput>VBoxManage clonevm</userinput> command to clone a VM. See
