My question was marked as a duplicate, and sincerely, I don't get it. Please explain it to me. My question: [Best practice: mitigating OOM kills of KVM VMs \[duplicate\]][1]<br> The other: [Using linux oom_score_adj to aim the oom daemon at the right target][2] So, in my question I ask "What can I do to do ABC", while the other asks "How do I use instrument XYZ". I see that usage of instrument XYZ is an answer and achieves goal ABC. But the two questions aren't the same. So the other question together with its answer would be a valuable answer to my question, since I didn't know about `oom_score_adj`. So, I really don't understand it and I would really appreciate somebody explaining this to me. If I can't ask such questions here, where else could I go? Especially since such questions are out of scope for SO and SU.
