1. INTRODUCTION:-As we all know, virtualization is the requirement of the future. We have evolved from the era of traditional environment to virtual environment. We have become accustomed to almost everything that is virtual, from virtual memory to virtual networks to virtual storage. The most widely leveraged benefit of virtualization technology is server consolidation, which allows one server to manage the workloads of multiple servers. For example, by consolidating a branch office's print server, fax server, Exchange server, and Web server onto a single Windows server, companies reduce hardware, maintenance, and personnel costs. In 2008, Microsoft released Hyper-V, its first metal hypervisor-based technology, integrated into Windows Server 2008. Hyper-V helped the organization efficiently use its hardware resources, reducing the total cost of ownership of the infrastructure. Hyper-v can run in independent virtual environments, with different operating systems and resource requirements, within the same physical server.1.1 Background:-Microsoft hyper-v, code-named viridian and formerly known as Windows Server virtualization, is a hypervisor-based virtualization system for x86-64 systems. Starting with Windows Server 2008, a beta version of Hyper-V shipped with some x86-64 editions of Windows Server 2008; Server virtualization via hyper-v technology has been an integral part of the operating system. The final version (automatically updated via Windows Update) was released on June 26, 2008. Hyper-v has since been released in a free standalone version and has been updated to version 2 (r2) status, further enhanced with service pack 1 (sp1).There are two manifestations of hyper-v technology:• Hyp...... middle of paper......child partition that hosts guest operating systems. Create a child partition using hyper-call. No partition has access to the physical processors, it has no authority to handle processor interrupts. The hypervisor handles interrupts to the processor and redirects them to the respective partition.2.2. 1 Hyper-V and type 1 virtualization: Hyper-V is the bare metal hypervisor-based technology built into Windows Server 2008. In bare metal hypervisor-based virtualization, a hypervisor runs directly on the host system hardware and is responsible of sharing physical hardware resources with multiple virtual machines. BARE METAL HYPERVISOR BASED VIRTUALIZATION. In basic terms, the main purpose of the hypervisor is to manage the physical CPU and memory allocation between the various virtual machines
