Problem
The ZFS ARC (Adaptive Replacement Cache) is configured to use almost all available free memory. This often results in insufficient free memory to launch a virtual machine, triggering a concerning memory over-commitment dialog.
Solution
Include the shrinkable ZFS ARC cache in the calculation of free memory to prevent the ENOMEM (Out of Memory) warning.
