8	<ph conkeyref="vbox-conkeyref-phrases/product-name"/> supports <i>nested
9	virtualization</i>. This feature enables the passthrough of
10	hardware virtualization functions to the guest VM. That means that
11	you can install a hypervisor, such as <ph conkeyref="vbox-conkeyref-phrases/product-name"/>, Oracle VM
12	Server or KVM, on an <ph conkeyref="vbox-conkeyref-phrases/product-name"/> guest. You can then create and
13	run VMs within the guest VM.
14	</p>
15	<p>
16	Hardware virtualization features not present on the host CPU will
17	not be exposed to the guest. In addition, some features such as
18	nested paging are not yet supported for passthrough to the guest.
19	</p>
20	<p>
21	You can enable the nested virtualization feature in one of the
22	following ways:
23	</p>
24	<ul>
25	<li>
26	<p>
27	From <ph conkeyref="vbox-conkeyref-phrases/vbox-mgr"/>, select the <b outputclass="bold">Enable
28	Nested VT-x/AMD-V</b> check box on the
29	<b outputclass="bold">Processor</b> tab. To disable the
30	feature, deselect the check box.
31	</p>
32	</li>
33	<li>
34	<p>
35	Use the <codeph>--nested-hw-virt</codeph> option of the <userinput>VBoxManage
36	modifyvm</userinput> command to enable or disable nested virtualization. See
37	<xref href="vboxmanage-modifyvm.dita">VBoxManage modifyvm</xref>.
