I wonder how this behaves with VMs, does this help when the host uses this scheduling, but the VM not? Does both make sense? - the vm threads are probably not pinned to cores.

In an case, a great boost for containers on bare metal or maybe core-pinned VMs.

I am not sure how much KVM instance’s processes are invisible to the host. KVM is very thin.
