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 performance.
When used as a virtualizer, QEMU achieves near native
performances by executing the guest code directly on the
host CPU. 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.
