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.
