What is the process called that allows a single host computer to manage multiple guest operating systems or virtual machines?

The process that enables a single host computer to manage multiple guest operating systems or virtual machines is known as virtualization. This technology allows the host system to create instances of virtual machines that operate independently with their own operating systems, applications, and resources. Virtualization optimizes hardware usage, increases efficiency, and enhances the ability to run different operating systems on a single physical machine, making it a foundational technology for cloud computing and data centers.

Containerization, while related, refers specifically to the packaging of applications and their dependencies into containers that can run on any computing environment. It doesn't manage multi-OS environments like virtualization does. Application streaming involves delivering software applications to endpoints without the need for local installation, which is distinct from running multiple OS instances on one host. Hyperconverged infrastructure integrates storage, computing, and networking into a single system but doesn't specifically define the management of multiple guest OS environments as virtualization does.
