I find it more consistent that qemu-system-* is doing emulation (and can
usually be ignored) and qemu-kvm is doing virtualization. It's more
intuitive to launch qemu-system-x86_64 than "qemu-kvm --no-kvm".
What we could do is automatically install a qemu-kvm binary for the
"most suitable" target that has KVM enabled (i.e. for
qemu-system-x86_64, not qemu-system-i386) instead of leaving it to distros.
