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