Hypervisor What is a Hypervisor in Virtualisation? A hypervisor is software or hardware that creates and manages virtual machines (VMs) by allocating resources from a physical host to multiple virtual environments. Explanation Hypervisors allow multiple operating systems to run on a single physical machine, optimising resource utilisation and enabling scalability. They are widely used in cloud computing and data centres. Practical Example of a Hypervisor A company uses a hypervisor to run multiple virtual servers on one physical machine, reducing hardware costs and improving operational efficiency.
