In libguestfs I have:

  Requires:      libvirt-daemon-qemu >= 0.10.2-3
  %ifarch %{ix86} x86_64
  Requires:      libvirt-daemon-kvm >= 0.10.2-3
  %endif

because I don't know if I'm going to be needing TCG or can use KVM.

Although, qemu-kvm is now an empty package ..  So all I really want is
qemu-system-%{arch}.

There's also code in libguestfs (src/launch-libvirt.c:parse_capabilities)
to parse the capabilities output looking for qemu or kvm.  It would be
nice if there was a "best" option instead.
