  94 for Linux on x86 hardware containing virtualization extensions (Intel VT or

  96 core virtualization infrastructure and a processor specific module,
  97 kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is
  98 underway to get the required changes upstream.")

 140      "QEMU is a generic and open source machine emulator and virtualizer.
 141
 142 When used as a machine emulator, QEMU can run OSes and programs made for one
 143 machine (e.g. an ARM board) on a different machine
 144 (e.g. your own PC).  By using dynamic translation, it achieves very good
 145 performance.
 146
 147 When used as a virtualizer, QEMU achieves near native performances by
 148 executing the guest code directly on the host CPU.  QEMU supports
 149 virtualization when executing under the Xen hypervisor or using
 150 the KVM kernel module in Linux.  When using KVM, QEMU can virtualize x86,
 151 server and embedded PowerPC, and S390 guests.")))
