Why in VirtualBox in the internal OS shows “2GB of RAM in use”, but in the external one these 2GB are nowhere to be found?

Launched VirtualBox on Windows 7 - 10 Windows. ON the external OS shows that the RAM for all processes of the internal running OS is 200 MB from strength.
Then I go to the task manager of the OS running in the virtual machine, and 2GB is used there ??? That is, I wound up 1.8 GB of RAM free from space, or does the internal machine plus with the external one?

(And if anyone knows why there is visual studio in the windows 10 image for virtualBox)? Was it somehow copied from an external OS, or was it in the visual studio package)

Apparently, either only user processes are displayed, or RAM is consumed in kernel mode (RAM is allocated to the driver and is not in the list of processes).
In any case, the first thing the system needs to track the consumption of RAM is according to the graph of RAM consumption, and not according to the list of processes.

VirtualBox is able to allocate RAM only as it is used (and if OS add-ons are installed in the guest, then release it back)

Because the nifa dispatcher can't display.
Try to look through RAMMap.
