Ksm high load



 
I have had ksm[2] causing a high load (on recent centos7), such things 
have been reported before[1]. I suspect that this could be related to 
windows vm's. I am having not that many vm's in the current setup, and 
this load increased on the hosts with a few windows vm's that are 
already generating more load that others.

Is there a way to disable ksm for specific vm's in the libvirt config 
xml?
