 117      "QEMU is a generic machine emulator and virtualizer.
 118
 119 When used as a machine emulator, QEMU can run OSes and programs made for one
 120 machine (e.g. an ARM board) on a different machine---e.g., your own PC.  By
 121 using dynamic translation, it achieves very good performance.
 122
 123 When used as a virtualizer, QEMU achieves near native performances by
 124 executing the guest code directly on the host CPU.  QEMU supports
 125 virtualization when executing under the Xen hypervisor or using
 126 the KVM kernel module in Linux.  When using KVM, QEMU can virtualize x86,
 127 server and embedded PowerPC, and S390 guests.")
