Memory Page sharing is Inactive under genral tab of RHEVM-H 3.0

Latest response




I have checked the RHEV hypervisor 3.0 general tab and Memory Page sharing is Inactive, so how to active this or it depend upon some specific hardware?


I believe it will be activated and kicked in automatically once the memory utilization of the hypervisor reaches 80%.


Please start some vms and run memory intensive tests on them and see it getting activated.

KSM takes up some resources, so it doesn't run constantly. It starts when the host reaches high memory usage, deduplicates the currently consumed RAM, and gets turned off again. There is no need to keep it running constantly
