What is the function of CPU in a virtual machine?

The CPU, or Central Processing Unit, functions as the brain of a virtual machine, executing tasks required for applications running within that virtual environment. In essence, when a virtual machine is created, it operates as a separate entity, and the CPU handles all the calculations and processing that applications demand. This includes executing instructions, performing computations, and managing the execution of different processes.

While the other options represent important functions in computing, they do not specifically align with the role of the CPU in a virtual machine. For instance, storing data is a task typically handled by storage devices, managing network connections falls under the purview of network interfaces, and memory allocation is primarily the responsibility of the operating system or hypervisor managing the virtual resources. The primary function of the CPU is to perform the computational work required to run applications, making it integral to the operation of any virtual machine.
