Virtual Machine Manager (VMM) is a software tool that allows users to create, manage, and monitor virtual machines (VMs) on a physical server. It provides a centralized interface for managing multiple VMs, enabling efficient resource allocation and performance optimization. VMM is commonly used in data centers and cloud environments to streamline operations and improve scalability. With VMM, users can easily deploy new VMs, configure their settings, and manage their lifecycle. It supports various operating systems and applications, making it versatile for different workloads. Additionally, VMM enhances security and backup options, ensuring that virtual environments are reliable and resilient.
