When used as a machine emulator, QEMU can run OSes and programs made for
|
|
|
|
|
one machine (e.g. an ARM board) on a different machine (e.g. your own PC).
|
|
|
|
|
By using dynamic translation, it achieves very good performances.

When used as a virtualizer, QEMU achieves near native performances by
|
|
|
|
|
executing the guest code directly on the host CPU. A host driver called
|
|
|
|
|
the QEMU accelerator (also known as KQEMU) is needed in this case. The
|
|
|
|
|
virtualizer mode requires that both the host and guest machine use x86
|
|
|
|
|
compatible processors.
