[http://wiki.qemu.org/Main_Page '''QEMU''']   is a [http://engeneric and open source machine emulator and virtualizer.wikipedia When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.org/wiki/Central_processing_unit processor] [http://eng.wikipediaan ARM board) on a different machine (e.org/wiki/Emulator emulator] that relies on dynamic [http://eng.wikipediayour own PC).org/wiki/Binary_translation binary By using dynamic translation] to achieve , it achieves very good performance.  When used as a reasonable speed while being easy to port virtualizer, QEMU achieves near native performances by executing the guest code directly on new the host CPU architectures.QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, and S390 guests.  
In conjunction with CPU emulation, it also provides a set of device models, allowing it to run a variety of unmodified guest [http://en.wikipedia.org/wiki/Operating_system operating systems]; it can thus be viewed as a [http://en.wikipedia.org/wiki/Virtual_machine_monitor#Classification hosted virtual machine monitor]. It also provides an accelerated mode for supporting a mixture of binary translation (for kernel code) and native execution (for user code), in the same fashion as [http://en.wikipedia.org/wiki/VMware_Workstation VMware Workstation] and [http://en.wikipedia.org/wiki/VirtualBox VirtualBox]. QEMU can also be used purely for CPU emulation for user level processes, allowing applications compiled for one architecture to be run on another.
