But the qemu-kvm binary can still run in TCG mode - you don't need to
install the QEMU emulators too. So your dep could be
%ifarch %{ix86} x86_64
Requires: libvirt-daemon-kvm >= 0.10.2-3
%else
Requires: libvirt-daemon-qemu >= 0.10.2-3
%endif
thus avoiding install of QEMU emulators unless they're the only
option available.
