+SELinux
+-------
+
+I have SELinux enabled on all nodes of my cluster. However it wasn't
+easy to get this far. In particular you need to enable one or
+probably both of these booleans:
+
+ setsebool -P virt_use_nfs on
+ setsebool -P use_nfs_home_dirs on
+
+Other tips
+----------
+
+Install ntp on all the nodes so that the date is kept in synch.
+
+Install lm_sensors on all nodes so you can monitor temperature, fan
+speed and so on.
