    VMX Swap Files
    Virtual machine executable (VMX) swap files allow the host to greatly reduce the amount of overhead memory
    reserved for the VMX process.
    NOTE VMX swap files are not related to the swap to host cache feature or to regular host-level swap files.
    ESXi reserves memory per virtual machine for a variety of purposes. Memory for the needs of certain
    components, such as the virtual machine monitor (VMM) and virtual devices, is fully reserved when a virtual
    machine is powered on. However, some of the overhead memory that is reserved for the VMX process can be
    swapped. The VMX swap feature reduces the VMX memory reservation significantly (for example, from about
    50MB or more per virtual machine to about 10MB per virtual machine). This allows the remaining memory to
    be swapped out when host memory is overcommitted, reducing overhead memory reservation for each virtual
    machine.
    The host creates VMX swap files automatically,
