Use a standard heading format for the index.rst file in a directory. Using overlines makes it clear that individual documents can use e.g. === for chapter titles and --- for section titles, as suggested in the Linux kernel guidelines[1]. They could do it anyway, because documents included in a toctree are parsed separately and therefore are not tied to the same conventions for headings. However, keeping some consistency is useful since sometimes files are included from multiple places.

About QEMU
|
|
----------
|
|
|
|
QEMU is a generic and open source machine emulator and virtualizer.
|
|
|
|
QEMU can be used in several different ways. The most common is for
|
|
"system emulation", where it provides a virtual model of an
|
|
entire machine (CPU, memory and emulated devices) to run a guest OS.
|
|
In this mode the CPU may be fully emulated, or it may work with
|
|
a hypervisor such as KVM, Xen, Hax or Hypervisor.Framework to
|
|
allow the guest to run directly on the host CPU.
|
|
|
|
The second supported way to use QEMU is "user mode emulation",
|
|
where QEMU can launch processes compiled for one CPU on another CPU.
|
|
In this mode the CPU is always emulated.
|
|
|
|
QEMU also provides a number of standalone commandline utilities,
|
|
such as the ``qemu-img`` disk image utility that allows you to create,
|
|
convert and modify disk images.
