What is Virtualization• Virtualization is a proven

software technology that makes it possible to run multiple operating systems and applications on the same server at the same time.

• It’s transforming the IT landscape and fundamentally changing the way that people utilize technology.

Benefits of Virtualization• Reduce capital and operating costs.• Deliver high application availability.• Minimize or eliminate downtime.• Increase IT productivity, efficiency, agility and responsiveness.• Speed and simplify application and resource provisioning.• Support business continuity and disaster recovery.• Enable centralized management.• Build a true Software-Defined Data Centre.

The Virtual Machine• A virtual machine (VM) is an emulation of a particular computer

system.• Virtual machines operate based on the computer architecture and

functions of a real or hypothetical computer, and their implementations may involve specialized hardware, software, or a combination of both.

• Multiple virtual machines can operate concurrently on a single x86 host system.

• Each one can run a different operating system and application stack.

Key Properties of Virtual Machine• Partitioning

Run multiple operating systems on one physical machine

Divide system resources between virtual machines

ESX Server stands for Enterprise Server X.

Key Properties of Virtual Machine (Cont.)

• Isolation Fault and security isolation at the

hardware level Advanced resource controls preserve

performance

Key Properties of Virtual Machine (Cont.)

• Encapsulation Entire state of the virtual machine

can be saved to files Move and copy virtual machines as

easily as moving and copying files

Key Properties of Virtual Machine (Cont.)

• Hardware-Independence Provision or migrate any virtual

machine to any similar or different physical server

Types of Virtualization• Server Virtualization• Network Virtualization• Software-Defined Storage• Desktop Virtualization• Hardware Virtualization

Virtualization Technology Companies

• VMware (VMWare Workstation)• Citrix• Oracle (Virtual Box)• Microsoft• Red Hat• Amazon• Google

VMware Workstation• VMware Workstation is a hypervisor that runs on x86-64 computers.• It is developed and sold by VMware, Inc., a division of EMC Corporation.• It enables users to set up one or more virtual machines (VMs) on a single

physical machine, and use them simultaneously along with the actual machine.

• Each virtual machine can execute its own operating system, including versions of Microsoft Windows, Linux, BSD, and MS-DOS.

• The Latest Version of VMWare is 11.1.2 which released on 15th June 2015.

VMware Tools• VMware Tools is a package with drivers and other software that can

be installed in guest operating systems to increase their performance. It has several components, including the following:• Drivers for the emulated hardware

• VESA-compliant graphics for the guest machine to access high screen resolutions

• Network drivers for the vmxnet2 and vmxnet3 NIC• Mouse integration

VMware Tools (Cont.)• Drag-and-drop file support• Clipboard sharing between host and guest• Time synchronization capabilities (guest syncs with host

machine's clock)
