I have a guest VM (RHEL 7.9) running inside Proxmox VE 8.2.3, configured with "dynamic memory": Ballooning Device checked, Minimum memory: 16384 (16GiB), Memory: 122880 (120GiB)
There is no memory pressure on the host (well under the 80% threshold noted in the docs). I have disabled OOM Killer and I'm running a python script to consume all available memory on the guest. It has been running for over an hour now, and the server still only shows 94 GB of memory (with OOM Killer enabled this script would have been killed long ago).
My question is whether this is expected/normal behavior? If so, how can I configure OOM Killer to play nicely with dynamic memory..?
