<div class="PlainText">Hi,<br>
<br>
while testing oVirt 3.5 RC I've came across this cluster setting:<br>
<br>
Optimization -> KSM control -> [X] Enable KSM<br>
<br>
I guess it's related to Kernel Same-page Merging.<br>
Since KSM is a bad idea in my case (really slow CPUs), I've disabled <br>
this Cluster setting, expecting oVirt to disable KSM on each oVirt Node.<br>
But KSM is still running and consuming a lot CPU.<br>
<br>
1) What is the expected result for this setting?<br>
2) And how do I completely and permanentely disable KSM on oVirt Nodes?<br>
<br>
<br>
Regards<br>
