<title>Cloning Virtual Machines</title>
<body>
<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 a
cloned VM to experiment with a VM configuration, to test different
guest OS levels, or to back up a VM.
</p>
<p>
The <b outputclass="bold">Clone Virtual Machine</b> wizard
guides you through the cloning process.
</p>
<p>
You can start the Clone Virtual Machine wizard in one of the
following ways:
</p>
<ul>
<li>
<p>
Click the VM name in the machine list and then select
<b outputclass="bold">Clone</b> from the
<b outputclass="bold">Machine</b> menu.
</p>
</li>
<li>
<p>
Click <b outputclass="bold">Clone</b> in the
<b outputclass="bold">Snapshots</b> window for the
selected VM.
</p>
</li>
</ul>
<note>
<p>
The <b outputclass="bold">Clone</b> menu item is disabled
while a virtual machine is running.
</p>
</note>
<p>
The <b outputclass="bold">New Machine Name and Path</b>
page is displayed.
</p>
<fig id="fig-clone-wizard-name-path">

</xref>
<image href="images/clone-vm-1.png" width="10cm" placement="break" platform="ohc">

</image>
</fig>
<p>
The following clone options are available:
</p>
<ul>
<li>
<p><b outputclass="bold">Name:</b> A name for the cloned
machine.
</p>
</li>
<li>
<p><b outputclass="bold">Path:</b> Choose a location for
the cloned virtual machine, otherwise Oracle VM VirtualBox uses the
default machines folder.
</p>
</li>
<li>
<p><b outputclass="bold">MAC Address Policy:</b> Specifies
whether to retain network card MAC addresses when cloning the
VM.
</p>
<p>
For example, the <b outputclass="bold">Generate New MAC
Addresses For All Network Adapters</b> value assigns a
new MAC address to each network card during cloning. This is
the default setting. This is the best option when both the
source VM and the cloned VM must operate on the same network.
Other values enable you to retain the existing MAC addresses
in the cloned VM.
</p>
</li>
<li>
<p><b outputclass="bold">Keep Disk Names:</b> Retains the
disk image names when cloning the VM.
</p>
</li>
<li>
<p><b outputclass="bold">Keep Hardware UUIDs:</b> Retains
the hardware universally unique identifiers (UUIDs) when
cloning the VM.
</p>
</li>
</ul>
<p>
Click <b outputclass="bold">Next</b>. The
<b outputclass="bold">Clone Type</b> page is displayed.
</p>

</fig>
<p>
The <b outputclass="bold">Clone Type</b> option specifies
whether to create a clone that is linked to the source VM or to
create a fully independent clone:
</p>
<ul>
<li>
<p><b outputclass="bold">Full Clone:</b> Copies all
dependent disk images to the new VM folder. A full clone can
operate fully without the source VM.
</p>
</li>
<li>
<p><b outputclass="bold">Linked Clone:</b> Creates new
differencing disk images based on the source VM disk images.
If you select the current state of the source VM as the clone
point, Oracle VM VirtualBox creates a new snapshot.
</p>
</li>
</ul>
<p>
(Optional) Click <b outputclass="bold">Next</b>. The
<b outputclass="bold">Snapshots</b> page is displayed.
</p>
<note>
<p>
The Snapshots page is only displayed for machines that have
snapshots and the selected clone type is
<b outputclass="bold">Full Clone</b>.
</p>

<image href="images/clone-vm-3.png" width="10cm" placement="break" platform="ohc">
<alt>Clone Virtual Machine Wizard: Snapshots</alt>
</image>
</fig>
<p>
You use this page to select which parts of the snapshot tree to
include in the clone. The available options are as follows:
</p>
<ul>
<li>
<p><b outputclass="bold">Current Machine State:</b> Clones
the current state of the VM. Snapshots are not included.
</p>
</li>
<li>
<p><b outputclass="bold">Everything:</b> Clones the
current machine state and all its snapshots.
</p>
</li>
</ul>
<p>
Click <b outputclass="bold">Finish</b> to start the clone
operation.
</p>
<p>
The duration of the clone operation depends on the size and number
of attached disk images. In addition, the clone operation saves
all the differencing disk images of a snapshot.
</p>
<p>
You can also use the <userinput>VBoxManage clonevm</userinput> command
to clone a VM. See <xref href="man_VBoxManage-clonevm.dita#vboxmanage-clonevm"/>.
