Estudiando, encuentro un punto interesante respecto a la paginación en Host y VM:
Use virtual memory. RAM is a limited resource and to optimize what is available, all Windows operating systems use a feature called virtual memory. Virtual memory is a combination of the available physical memory and a file called the paging file. The paging file, Pagefile.sys, is a performance feature in Windows that allows the operating system to use temporary memory pages until there is sufficient physical memory available. All applications and many system processes use virtual memory addresses, which are later translated to physical memory addresses. By default, Windows sets the size of the paging file equal to the system memory. To optimize the virtual memory, you should set the paging file to 1.5 times of the physical memory on your virtualization server. However, the paging file only works for the host operating system. The paging file that Windows creates automatically within the virtual machine is useless, and you can remove it completely.
