> CPU isolation allows the user to specify CPU cores that are to be explicitly reserved for assignment (to VMs or Docker containers).
>
> This is incredibly important for gaming VMs to run smoothly because even if you manually pin your Docker containers to not overlap with your gaming VM,
> the host OS can still utilize those same cores as the guest VM needs for things like returning responses for the webGui, running a parity check, btrfs operations, etc.
