By using dynamic translation, it achieves very good performances. -When used as a virtualizer, QEMU achieves near native performances by -executing the guest code directly on the host CPU. A host driver called -the QEMU accelerator (also known as KQEMU) is needed in this case -(contained in the optional dependency kqemu). The virtualizer mode -requires that both the host and guest machine use x86 compatible -processors. +qemu-kvm achieves near native performances by leveraging the kvm-kmod +modules and executing the guest code directly on the host CPU. +Slackware provides pre-built 32/64 bit x86 kvm-kmod modules or you can +build different versions with the kvm-kmod package. +qemu-kvm code has been merged back into qemu since version 1.3.0. -NOTE: -qemu builds man-pages at compile-time; to do so, /sbin must be in the -current $PATH.
