|
QEMU is a FAST! processor emulator using dynamic translation to
|
|
achieve good emulation speed.
|
|
|
|
QEMU has two operating modes:
|
|
|
|
@itemize
|
|
@item Full system emulation. In this mode, QEMU emulates a full system (for
|
|
example a PC), including one or several processors and various
|
|
peripherals. It can be used to launch different Operating Systems
|
|
without rebooting the PC or to debug system code.
|
|
|
|
@item User mode emulation. In this mode, QEMU can launch
|
|
processes compiled for one CPU on another CPU. It can be used to
|
|
launch the Wine Windows API emulator (@url{https://www.winehq.org}) or
|
|
to ease cross-compilation and cross-debugging.
|
|
|
|
@end itemize
|
|
|
|
QEMU has the following features:
|
|
|
|
@itemize
|
|
@item QEMU can run without a host kernel driver and yet gives acceptable
|
|
performance. It uses dynamic translation to native code for reasonable speed,
|
|
with support for self-modifying code and precise exceptions.
|
|
|
|
@item It is portable to several operating systems (GNU/Linux, *BSD, Mac OS X,
|
|
Windows) and architectures.
|
|
|
|
@item It performs accurate software emulation of the FPU.
|
|
@end itemize
|
|
|
|
QEMU user mode emulation has the following features:
|
|
@itemize
|
|
@item Generic Linux system call converter, including most ioctls.
|
|
|
|
@item clone() emulation using native CPU clone() to use Linux scheduler for threads.
|
|
|
|
@item Accurate signal handling by remapping host signals to target signals.
|
|
@end itemize
|
|
|
|
QEMU full system emulation has the following features:
|
|
@itemize
|
|
@item
|
|
QEMU uses a full software MMU for maximum portability.
|
|
|
|
@item
|
|
QEMU can optionally use an in-kernel accelerator, like kvm. The accelerators
|
|
execute most of the guest code natively, while
|
|
continuing to emulate the rest of the machine.
|
|
|
|
@item
|
|
Various hardware devices can be emulated and in some cases, host
|
|
devices (e.g. serial and parallel ports, USB, drives) can be used
|
|
transparently by the guest Operating System. Host device passthrough
|
|
can be used for talking to external physical peripherals (e.g. a
|
|
webcam, modem or tape drive).
|
|
|
|
@item
|
|
Symmetric multiprocessing (SMP) support. Currently, an in-kernel
|
|
accelerator is required to use more than one host CPU for emulation.

@chapter QEMU System emulator targets
|
|
|
|
QEMU is a generic emulator and it emulates many machines. Most of the
|
|
options are similar for all machines. Specific information about the
|
|
various targets are mentioned in the following sections.
