This affects both system and user mode emulation so we should probably list it up front. Acked-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20230124180127.1881110-21-alex.bennee@linaro.org>

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
|
|
:ref:`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 :ref:`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 :ref:`command line
|
|
utilities<Tools>`, such as the ``qemu-img`` disk image utility that
|
|
allows you to create, convert and modify disk images.
