|

| 8 | You can create a full copy or a linked copy of an existing VM.
|
|---|
| 9 | This copy is called a <i>clone</i>. You might use a
|
|---|
| 10 | cloned VM to experiment with a VM configuration, to test different
|
|---|
| 11 | guest OS levels, or to back up a VM.
|
|---|
| 12 | </p>
|
|---|
| 13 | <p>
|
|---|
| 14 | The <b outputclass="bold">Clone Virtual Machine</b> wizard
|
|---|
| 15 | guides you through the cloning process.
|
|---|
| 16 | </p>
|
|---|
| 17 | <p>
|
|---|
| 18 | You can start the Clone Virtual Machine wizard in one of the
|
|---|
| 19 | following ways:
|
|---|
| 20 | </p>
|
|---|
| 21 | <ul>
|
|---|
| 22 | <li>
|
|---|
| 23 | <p>
|
|---|
| 24 | Click the VM name in the machine list and then select
|
|---|
| 25 | <b outputclass="bold">Clone</b> from the
|
|---|
| 26 | <b outputclass="bold">Machine</b> menu.
|
|---|
| 27 | </p>
|
|---|
| 28 | </li>
|
|---|
| 29 | <li>
|
|---|
| 30 | <p>
|
|---|
| 31 | Click <b outputclass="bold">Clone</b> in the
|
|---|
| 32 | <b outputclass="bold">Snapshots</b> window for the
|
|---|
| 33 | selected VM.
|
|---|
| 34 | </p>
|
|---|
| 35 | </li>
|
|---|
| 36 | </ul>
|
|---|
| 37 | <note>
|
|---|
| 38 | <p>
|
|---|
| 39 | The <b outputclass="bold">Clone</b> menu item is disabled
|
|---|
| 40 | while a virtual machine is running.
|
|---|
| 41 | </p>
|

| 42 | </note>
|
|---|
| 43 | <p>
|

| 44 | The <b outputclass="bold">New Machine Name and Path</b>

|

| 52 | The following clone options are available:
|

| 53 | </p>
|
|---|
| 54 | <ul>
|
|---|
| 55 | <li>
|
|---|
| 56 | <p><b outputclass="bold">Name:</b> A name for the cloned
|
|---|
| 57 | machine.
|
|---|
| 58 | </p>
|
|---|
| 59 | </li>
|
|---|
| 60 | <li>
|
|---|
| 61 | <p><b outputclass="bold">Path:</b> Choose a location for
|
|---|
| 62 | the cloned virtual machine, otherwise Oracle VM VirtualBox uses the
|
|---|
| 63 | default machines folder.
|
|---|
| 64 | </p>
|
|---|
| 65 | </li>
|
|---|
| 66 | <li>
|
|---|
| 67 | <p><b outputclass="bold">MAC Address Policy:</b> Specifies
|
|---|
| 68 | whether to retain network card MAC addresses when cloning the
|
|---|
| 69 | VM.
|
|---|
| 70 | </p>
|
|---|
| 71 | <p>
|
|---|
| 72 | For example, the <b outputclass="bold">Generate New MAC
|
|---|
| 73 | Addresses For All Network Adapters</b> value assigns a
|
|---|
| 74 | new MAC address to each network card during cloning. This is
|
|---|
| 75 | the default setting. This is the best option when both the
|
|---|
| 76 | source VM and the cloned VM must operate on the same network.
|
|---|
| 77 | Other values enable you to retain the existing MAC addresses
|
|---|
| 78 | in the cloned VM.

| 102 | The <b outputclass="bold">Clone Type</b> option specifies

|

| 108 | <p><b outputclass="bold">Full Clone:</b> Copies all

|
|---|
| 110 | operate fully without the source VM.
|

| 111 | </p>
|

| 112 | </li>
|

| 113 | <li>
|

| 114 | <p><b outputclass="bold">Linked Clone:</b> Creates new
|
|---|
| 115 | differencing disk images based on the source VM disk images.
|
|---|
| 116 | If you select the current state of the source VM as the clone
|
|---|
| 117 | point, Oracle VM VirtualBox creates a new snapshot.
|

|

| 127 | The Snapshots page is only displayed for machines that have

| 141 | <li>
|

|

| 153 | Click <b outputclass="bold">Finish</b> to start the clone
|
|---|
| 154 | operation.
|
|---|
| 155 | </p>
|
|---|
| 156 | <p>
|
|---|
| 157 | The duration of the clone operation depends on the size and number
|
|---|
| 158 | of attached disk images. In addition, the clone operation saves
|
|---|
| 159 | all the differencing disk images of a snapshot.

|
|---|
| 162 | You can also use the <userinput>VBoxManage clonevm</userinput> command
|
|---|
| 163 | to clone a VM. See <xref href="man_VBoxManage-clonevm.dita#vboxmanage-clonevm"/>.
