while testing oVirt 3.5 RC I've came across this cluster setting: Optimization -> KSM control -> [X] Enable KSM [...] But KSM is still running and consuming a lot CPU.
It will have effect next host change to Up state (i.e. from Maintenance or from a reboot). Anyway, you can force the policy to have effect on the fly: select the cluster, click in Hosts sub-tab, select the host(s) and click "Sync MOM Policy".
Unfortunately, it doesn't work for me. Everytime I restart vdsmd it will automatically start ksm again (and ksmd starts consuming CPU). I couldn't find anything ksm-related in vdsm.log. Is there a way to debug this? I strongly assume that the KSM Custer setting isn't working as expected. FWIW, I've just upgraded to oVirt 3.5.0 GA and test this setting again. Regards - Frank
