I guess "telling the user in advance whether enabling kvm is going to work" (either via -help output or via monitor to tell libvirt about it) might want that, and for that matter maybe kvmtool might want to present a list of available CPUs. (I probably wouldn't implement the 'say if it's going to work in -help' bit immediately though because QEMU's internal structure makes it a little awkward. But if we might want it it's probably better for the kernel API to be there from the start.) -- PMM
