+# For XenServer version >= 6.5, use kernel_uname which should be
+# the `uname -r` output.
+# for example:
+#
+# rpmbuild -D "openvswitch_version 2.3.0+build123"
+# -D "kernel_uname 3.10.0+2"
+# -bb /usr/src/redhat/SPECS/openvswitch-xen.spec
+#
+# If tests have to be skipped while building, specify the '--without check'
+# option. For example:
+# rpmbuild -bb --without check xenserver/openvswitch-xen.spec
