[Users] Custom settings for Kernel Same-page Merging (KSM)?

Hi, recently I've noticed that ksmd is using quite a lot CPU on my oVirt node. While I have plenty RAM, my CPU is way slow. Thus ksmd is eating up the most limited ressource here. Is it supported to use custom settings for ksmd? I've noticed that it is handled by MoM: /etc/vdsm/mom.d/03-ksm.policy. May I just change some settings here, or is there a tuning parameter in oVirt engine? Couldn't find a matching one with engine-config. I'd like to use a higher value for sleep_millisecs to reduce CPU usage (with the possible side effect of higher RAM usage). Thanks - Frank
