What is QEMU ? (QEMU 7.0 released)

Qemu is all Emulator and Virtual Machine tools. When using Qemu as Simulator, QEMU can run OS and Programs built on one machine (Example ARM), on different machines.

When used as a virtualizer, QEMU achieves near-native performance by executing guest code directly on the host CPU. QEMU supports virtualization when run under the Xen hypervisor or using the KVM kernel module on Linux. When using KVM, QEMU can virtualize x86, embedded PowerPC servers and, 64-bit POWER, S390, 32-bit and 64-bit ARM, and MIPS guests.
