+> 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.
