QEMU is a generic and open source machine emulator and virtualizer.

QEMU is a powerful, open-source machine emulator which allows you to run virtually any operating system inside your currently running distribution. In this brief tutorial I'll show how to run distributions for which the ISO is available, directly from within Debian or Ubuntu.

QEMU lets you emulate a machine —in other words, you can run a virtual computer on top of your real computer. This makes it perfect for trying and testing the latest release of a distribution, running older operating systems, or just testing.

This week there was the release of QEMU 0.12.2 (and the subsequent release of KVM-QEMU 0.12.2) with support for block migration, but this point release was mostly made up of small fixes and tweaks. IBM's Anthony Liguori though has begun making plans for the next major release of this open-source processor emulator.

QEMU, the popular open-source processor emulator that can be run as a user-space program and also has found its way into use by the KVM and VirtualBox projects, will soon reach version 0.10.0

Create a simple "Hello world" program that prints on the serial port of an emulated ARM system, using the CodeSourcery gcc toolchain and the QEMU emulator of the Versatile board.

What is QEMU? It's a free software "processor emulator", which means it's capable of running applications written for other systems natively on your current operating system.

If you have a fondness for old arcade games and want to play them again, try the Multiple Arcade Machine Emulator (MAME), a free emulator that lets you recreate the look and feel of old arcade game systems in software. While it's written for Windows, you can run this open source application under Linux.
