QEMU is a cross-platform processor emulator, allowing you to virtualize an entire PC. The KQEMU module allows significatn virtualization speedup when emulating an x86 processor on x86 hardware. The module was previously available as a binary-only add-on to the open-source QEMU. This recent relicensing makes QEMU a fully open-source, high-speed virtualization tool available to all.
