Core Software Application for Computer Virtualization

A.

The core software application that manages computer virtualization is called a hypervisor. A hypervisor, also known as a virtual machine manager, is a software layer that allows multiple virtual machines (VMs) to run on a single physical host machine, sharing its resources such as CPU, memory, and storage.

The hypervisor is responsible for creating and managing the virtual machines, providing each VM with a virtualized set of hardware resources, and isolating each VM from other VMs running on the same physical host. There are two types of hypervisors: Type 1 and Type 2.

Type 1 hypervisors, also called bare-metal hypervisors, run directly on the host machine's hardware, allowing multiple VMs to run on top of them. They are typically used in enterprise environments and data centers where performance, security, and reliability are critical.

Type 2 hypervisors, also known as hosted hypervisors, run on top of a host operating system (OS), allowing users to run multiple VMs on the host OS. They are typically used in development and testing environments, as well as on personal computers for running virtual machines.

Hyperthreading is a technology developed by Intel that allows a single physical CPU core to execute multiple threads simultaneously, improving CPU utilization and performance.

A console is a text-based interface used to interact with a computer system, such as a command-line interface or terminal.

KVM (Kernel-based Virtual Machine) is a type 1 hypervisor that runs on the Linux kernel and allows multiple virtual machines to run on a single physical host machine. It is an open-source solution that is widely used in data centers and cloud environments.

Therefore, the correct answer to the question is A. Hypervisor.
