QEMU is a generic and open source machine emulator and virtualizer.
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
(contained in the optional dependency kqemu). The virtualizer mode
requires that both the host and guest machine use x86 compatible
processors.
NOTE:
qemu builds man-pages at compile-time; to do so, /sbin must be in the
current $PATH. Be sure to run the script as root ( "su -" ).
spice is an optional dependency.
