What is host memory and is it allocated the same as a physical machine? Why or why not?

Solution

Host Memory usage is defined as the amount of host memory that is allocated to the virtual machine, Active Guest Memory is defined as the amount of guest memory that is currently being used by the guest operating system and its applications. These two statistics are quite useful for analyzing the memory status of the virtual machine and providing hints to address potential performance issues.Virtual memory is a well-known technique used in most general-purpose operating systems, and almost all modern processors have hardware to support it. Virtual memory creates a uniform virtual address space for applications and allows the operating system and hardware to handle the address translation between the virtual address space and the physical address space. This technique not only simplifies the programmer’s work, but also adapts the execution environment to support large address spaces, process protection, file mapping, and swapping in modern computer systems.
