 379 of QEMU is used only by the american fuzzy lop package.
 380
 381 When used as a machine emulator, QEMU can run OSes and programs made for one
 382 machine (e.g. an ARM board) on a different machine---e.g., your own PC.  By
 383 using dynamic translation, it achieves very good performance.
 384
 385 When used as a virtualizer, QEMU achieves near native performances by
 386 executing the guest code directly on the host CPU.  QEMU supports
 387 virtualization when executing under the Xen hypervisor or using
 388 the KVM kernel module in Linux.  When using KVM, QEMU can virtualize x86,
 389 server and embedded PowerPC, and S390 guests.")
