+ *
+ * libxl interface for setting VCPU affinity changed in 4.5. In fact, a new
+ * parameter has been added, representative of 'VCPU soft affinity'. If one
+ * does not care about it (and that's libvirt case), passing NULL is the
+ * right thing to do. To mark that change, LIBXL_HAVE_VCPUINFO_SOFT_AFFINITY
+ * is defined.
