So far, we are not reporting if numatune was even defined. The value of zero is blindly returned (which maps onto VIR_DOMAIN_NUMATUNE_MEM_STRICT). Unfortunately, we are making decisions based on this value. Instead, we should not only return the correct value, but report to the caller if the value is valid at all. For better viewing of this patch use '-w'. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
