Hello, I have a rather practical question, is it possible to limit amount of vm-initiated events for single VM? As and example, VM which experienced OOM and effectively stuck dead generates a lot of unnecessary context switches triggering do_raw_spin_lock very often and therefore increasing overall compute workload. This possibly can be done via reactive limitation of the cpu quota via cgroup, but such method is quite impractical because every orchestration solution will need to implement its own piece of code to detect such VM states and act properly. I wonder if there may be a proposal which will do this job better than userspace-implemented perf statistics loop.
