Package qemu: Information

QEMU is a fast processor emulator using dynamic translation to achieve
good emulation speed.  QEMU has two operating modes:

* Full system emulation.  In this mode, QEMU emulates a full system
  (for example a PC), including a processor and various peripherials.
  It can be used to launch different Operating Systems without rebooting
  the PC or to debug system code.

* User mode emulation.  In this mode, QEMU can launch Linux processes
  compiled for one CPU on another CPU.  It can be used to launch the
  Wine Windows API emulator or to ease cross-compilation and
  cross-debugging.

As QEMU requires no host kernel patches to run, it is very safe and easy
to use.
