  22           QEMU is a generic and open source machine emulator and virtualizer.
  23
  24           When used as a machine emulator, QEMU can run OSes and programs made
  25           for one machine (e.g. an ARM board) on a different machine (e.g.
  26           your own PC). By using dynamic translation, it achieves very good
  27           performance.
  28
  29           When used as a virtualizer, QEMU achieves near native performances
  30           by executing the guest code directly on the host CPU. QEMU supports
  31           virtualization when executing under the Xen hypervisor or using the
  32           KVM kernel module in Linux. When using KVM, QEMU can virtualize x86,
  33           server and embedded PowerPC, and S390 guests.
