However I want to point out that the advice above is also wrong: The ‘-enable-kvm’ option is obsolete, and that command would only work if you were emulating x86_64, which is by no means the only architecture which supports KVM. Really you should use libvirt rather than trying to formulate qemu command lines. > 2. wouldn't it make sense to convince upstream to provide /usr/bin/qemu-kvm > which would mean "provide accelerated emulation of current architecture"? Possibly, but what many people want is "be as fast as you can but don't break if KVM isn't available", which is provided by the ‘-machine accel=kvm:tcg’ option, or by using libvirt capabilities to discover what acceleration and emulation options are available on the current host.
