How To Install QEMU under FreeBSD 8.1 as Host OS

QEMU is a processor emulator that relies on dynamic binary translation to achieve a reasonable speed while being easy to port on new host CPU architectures.
When used as a machine emulator, QEMU can run Operating Systems and programs made for one machine on a different machine. By using dynamic translation, it achieves very good performance.
When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU.
