You got it completely backwards. Request doesn’t leave unused cpu as it is cpu.shares, limit does being cfs quota that completely prevents your process from scheduling even if nothing else is using cycles. Don’t believe me? here’s one of kubernetes founders saying same thing - https://www.reddit.com/r/kubernetes/comments/all1vg/comment/...

Incorrect. If a node has 2 cores and the pods on it have request of 2000m nothing else will schedule on that node even if total actual usage is 0.

You can overprovision limit.

This is easy to test for yourself.
