Up to RHEV 3.2, KSM was controlled by ksmtuned. Users wanting stop KSM just wanted to stop ksmtuned service in each host. In RHEV 3.3, vdsm stops ksmtuned and gives KSM control to MOM. MOM controls KSM and memory ballooning. We can disable memory ballooning using RHEV Admin Portal interface, unchecking "Enable Memory Balloon Optimization" on Cluster level, which will have effect in next Host "Up". Please provide the equivalent way to disable KSM using Admin Portal (and API as well). vdsm counterpart handled in http://bugzilla.redhat.com/1025780
