I even see this behavior when live migrating instances from a HPE G9 to another HPE G9 with the same CPU model, but different CPU flags. After applying HPE SPP 2018.3 there seems to be one additional CPU flag on the upgraded G9: spec_ctrl.

I like the idea of having a "auto_custom" cpu-mode but wonder if this bug tracker is the right place. shouldn't this be more an upstream bug?
