In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code. + +User mode emulation (Linux host only). In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU. + + +An optional proprietary QEMU Accelerator Module (kqemu) is available to optimize the case where a PC is emulated on a PC. This module enables QEMU to run most of the target application code directly on the host processor to achieve near native performance. + +This build of QEMU is built with support for kqemu. To achieve this, the QEMU build process probes for current kernel path. A different kernel path can be set by editing qemu.SlackBuild. QEMU and kqemu should be built and used against the same kernel version. +If you are not planning on using kqemu, you may edit the SlackBuild and remove the --enable-kqemu line if you wish.
