Generic machine emulator and virtualizer

QEMU is a generic 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 kernel driver called KVM is needed in this case. The virtualizer mode requires that both the host and guest machine use the same architecture of x86, PowerPC or S390.

It does not offer 3D acceleration.
