Thread: QEMU is a generic and open source machine emulator and virtualiser

QEMU is a generic and open source machine emulator and virtualiser. When used as a machine emulator, QE can run OSS and programs made for one machine (for example, an ARM board) on a different machine (for example, your own PC). By using dynamic translation, it achieves a very good performance. When used as a virtualiser, QEMU achieves near-native performances by executing the guest code directly on the host CPU.
