Vou citar a documentação on-line da VMware:
The VMkernel maps guest physical memory to machine memory. However, because of the VMkernel’s unique memory-management techniques, such as ballooning, memory-sharing, swapping, and other techniques, guest physical memory-to-machine memory mapping does not have a 1:1 correspondence. Specifically, the VMkernel can:
- Map multiple regions of guest physical memory to a single region of machine memory (which the VMkernel does for memory sharing among virtual machines)
- Leave specific regions of guest physical memory and machine memory unmapped (which the VMkernel does during swapping and ballooning)
Em outras palavras, esses valores não serão mapeados um por um, devido à maneira como o VMWare lida com a memória.
