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.")
