| 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 |
| performance. |
| |
| When used as a virtualizer, QEMU achieves near native performances |
| by executing the guest code directly on the host CPU. QEMU supports |
| virtualization when executing under the Xen hypervisor or using the |
| KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, |
| server and embedded PowerPC, and S390 guests. |
