So I have a gaming VM that runs 16 cores(pair threaded) with those cores isolated at boot. When mover or something is running in unraid I can 100% tell in game. Its like unraid is using those cores even though I have specifically said not to. A test I performed was run mover than run a "Dying Light" which usually runs at max fps at 1080p with nearly everything turned to max. When mover is running there is constant stutter. I traced this back to my first CPU core in the VM is showing around 85% utilization but unraid is saying its nearly 100%. It appears something is adding CPU usage on top of the actual usage. I then stop the mover and it shows what task manager shows in the VM. I would assume Unraid would use one of the other "64smt/32physical" cores that I have but it doesn't appear to want to.

Edit:
Realized I didn't show the CPU isolation stuff for booting
