QEMU is a generic and open source machine emulator and virtualizer.When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performances.

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.

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.

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

There might be the situation, that your root filesystem runs out of space, so it has to be expanded. With filesystems other than the root filesystem this could easily be done for instance with gparted. With the root filesystem this is not possible, as gparted could only expand filesystems that are not mounted, which is impossible with the root filesystem.

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.

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.
