manual: Split out the topics of converted manpages into separate files and generate ditamap files for each manpage to avoid needing to hardcode anything in UserManual.xml. This means that the topics inside a manpage can be supressed from the toc, but otoh, they get numbered (with 4.x). The per-topic files are named by refentry/refsect1/refsect2 @id and are currently not cleaned up by 'kmk clean'. bugref:10302
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`

8	Oracle VM VirtualBox 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 Oracle VM VirtualBox, Oracle VM
12	Server or KVM, on an Oracle VM VirtualBox 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 VirtualBox Manager, 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
36	<userinput>VBoxManage modifyvm</userinput> command to enable or
37	disable nested virtualization. See
38	<xref href="vboxmanage-modifyvm.dita">VBoxManage modifyvm</xref>.
