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

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.

In this post I prepared what I think is the simplest example on how to manage interrupts for the widespread ARM926 core. From this example one can expand the complexity of the interrupt management at will. I’m going to test the functionality with QEMU, emulating the Versatile Platform Baseboard.

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.

Virtual Machines are an easy way to provide new applications or even entire operating systems without the need to install or alter anything in an existing system. However, often they are provided as a qemu image while VirtualBox is much more userfriendly.

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.

A tutorial that shows how to debug an ARM Linux program inside a platform emulated with QEMU. The tutorial uses gdbserver to connect the program executing in the guest system to the debugger running on the host system.

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.

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.
