| About QEMU |
| ---------- |
| |
| QEMU is a generic and open source machine emulator and virtualizer. |
| |
| QEMU can be used in several different ways. 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. |
