Dear oVirt,

We are running 4.3.3 oVirt with SHE on three CentOS nodes for HA – with NFS storage.

We also have two Local Storage DCs managed by same SHE.

The issue we are reporting was present on 4.3.2 as well.

The memory usage on both hosts (third one is in maintenance mode) does not go above 45%:

I have also attached the UI Dashboard screenshot.

However, when trying to start one VM:

Engine reports that there is not enough memory and writes the following in the engine.log:

Current memory optimization is set to “None”
