+=== Appendix 1: Running a Private OML Server ===
+
+=== 1.1 OML ===
+More detailed information on OML and the its installation can be found [http://mytestbed.net/projects/oml/ here].
+
+----
+
+=== 1.2 Experiment controller ===
+
+The experiment controller configuration file, located at /etc/omf-expctl-5.4/omf-expctl.yaml, specifies which 
+oml server the nodes should communicate with.
+The snippet below show the current configuration that's in the file on the tutorial user workspace VM.
+
+{{{
+# URI to the OML server to use for this EC 
+# (can be overwritten on the EC command line)
+#:omluri: 'tcp:10.103.0.3:3003'
+:omluri: 'tcp:emmy9.casa.umass.edu:3003'
+}}}
+
+In case you were planning an experiment where the OML server is located somewhere else you would have to modify this line accordingly.
+You have to assure that the omluri is reachable from ALL nodes that participate in your experiment. This does not necessarily mean that the OML server has a public IP address. E.g., in the case of an experiment on an ExoGENI slice, the OML server can be located on one of the nodes of this slice.
+
+----
+
+=== 1.3 OML server on ExoGENI node ===
+
+The current [https://wiki.exogeni.net/doku.php?id=public:experimenters:images ExoGENI image] we currently use for the tutorial already comes with an OML server installed. This allows you to run an OML server of one of the nodes in your slice.
+
+ * Run OML server on one of the nodes in your slice.
+ * If you'd like to automatically store measurement results in iRODS you have to copy the hook script to ''/usr/share/oml2-server/'' and start the OML server with the ''-H <path_to_hook_script>'' flag.
+ * Configure '':omluri:'' entry ''/etc/omf-expctl-5.4/omf-expctl.yaml'' on the node where you run the experiment controller. (Note: this can be on a machine that's outside your ExoGENI slice, as it is the case for this tutorial.)
+ * Run your experiment.

+<span style="color:red">IMPORTANT NOTE!!!
+Make sure that you safe your experiment in persistent storage (e.g., iRODS) before you take down your slice. If you only keep a version on our ExoGENI node it'll be lost after the slice is removed!!
