1About QEMU 2========== 3 4QEMU is a generic and open source machine emulator and virtualizer. 5 6QEMU can be used in several different ways. The most common is for 7"system emulation", where it provides a virtual model of an 8entire machine (CPU, memory and emulated devices) to run a guest OS. 9In this mode the CPU may be fully emulated, or it may work with 10a hypervisor such as KVM, Xen, Hax or Hypervisor.Framework to 11allow the guest to run directly on the host CPU. 12 13The second supported way to use QEMU is "user mode emulation", 14where QEMU can launch processes compiled for one CPU on another CPU. 15In this mode the CPU is always emulated. 16 17QEMU also provides a number of standalone commandline utilities, 18such as the `qemu-img` disk image utility that allows you to create, 19convert and modify disk images. 20 21.. toctree:: 22 :maxdepth: 2 23 24 build-platforms 25 deprecated 26 removed-features 27 license 28
