KSM sharing 0

[chudak]

I am seeing KSM Sharing as 0 now and a bit surprised.
I think it used to allocated ~10GB before, but I did not pay lots of attention friendly.

I don't "feel" any performance issues and run 4 CTs + 3 VMs all the time on with 64GB RAM on the server.

Any clues?

TIA

By default KSM is only working when host's RAM usage exceeds 80%. KSM will cost performance, so no need to run it while there is plenty of free RAM left.

Thx
I disabled it for now

BTW the UI does not reflect that KSM is disabled, it'd be cool if it does show the status
