Detailed explanation-1: -A hypervisor, also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing.
Detailed explanation-2: -A hypervisor allows a physical server to operate multiple VMs as guests run alongside each other. Each VM can run a different OS. A hypervisor allocates each VM resource such as CPU, memory, storage, and network to run the guest OS and applications.
Detailed explanation-3: -Explanation: This makes virtual machine technology very useful for running old versions of operating systems, testing applications in what amounts to a sandbox.
Detailed explanation-4: -Acting as a VMM, the hypervisor monitors, pools and allocates resources-like CPU, memory and storage-across all guest VMs. By centralizing these assets, it’s possible to significantly reduce each VM’s energy consumption, space allocation and maintenance requirements while optimizing overall system performance.
Detailed explanation-5: -Hypervisor is a program that allows multiple Operating Systems to share a single physical hardware. Each operating system will share the host’s processor, memory, file storage, and other resources. The hypervisor controls the host processor and resources, allocating what is needed to each operating system.
