QEMU 3.1.0 Description:
QEMU It is also known as a machine emulator, engineered to emulate a full system, including a processor and its peripherals. The emulation part supports operating systems and programs created for a single hardware platform, but running on top of a different computer with a different architecture. On the other hand, when the application is used as a virtualizer, it can achieve almost native performances by running the guest code straight on the host processor. It supports the Xen hypervisor and the KVM (Kernel Virtual Machine) kernel module.
