 381 of QEMU is used only by the american fuzzy lop package.
 382
 383 When used as a machine emulator, QEMU can run OSes and programs made for one
 384 machine (e.g. an ARM board) on a different machine---e.g., your own PC.  By
 385 using dynamic translation, it achieves very good performance.
 386
 387 When used as a virtualizer, QEMU achieves near native performances by
 388 executing the guest code directly on the host CPU.  QEMU supports
 389 virtualization when executing under the Xen hypervisor or using
 390 the KVM kernel module in Linux.  When using KVM, QEMU can virtualize x86,
 391 server and embedded PowerPC, and S390 guests.")
