The most common is for +"system emulation", where it provides a virtual model of an +entire machine (CPU, memory and emulated devices) to run a guest OS. +In this mode the CPU may be fully emulated, or it may work with +a hypervisor such as KVM, Xen, Hax or Hypervisor.Framework to +allow the guest to run directly on the host CPU. + +The second supported way to use QEMU is "user mode emulation", +where QEMU can launch processes compiled for one CPU on another CPU. +In this mode the CPU is always emulated. + +QEMU also provides a number of standalone commandline utilities, +such as the `qemu-img` disk image utility that allows you to create, +convert and modify disk images. + .. toctree:: :maxdepth: 2 -- 2.20.1
