Easily:

Those below are currently used by MOM directly:

getAllVmStats
vmSetCpuTuneQuota
vmSetCpuTunePeriod
getIoTunePolicy
getIoTune
setIoTune
setKsmTune

We also have some verbs that are used by the engine and forwarded to MOM:

setMOMPolicyParameters
setMOMPolicy
updateVmPolicy


Btw, about stats collection:

Balloon stats are collected by VDSM
KSM stats are collected by MOM and VDSM grabs them in
vdsm.momIF.MomClient#getKsmStats
