This document discusses the installation of virtual machines. It begins with an introduction to virtual machines, noting that they allow software to emulate hardware and isolate operating systems. It then covers the need for virtual machines, including isolation, testing capabilities, snapshots, and replication. Finally, it discusses advantages like running multiple operating systems simultaneously, easy maintenance and recovery, before concluding that virtual machines provide discrete identical execution environments with greater isolation than a single operating system.

3. Virtual Machine
• A virtual machine (VM) is a software implementation of a
machine that executes programs like a physical machine.
• It shares physical hardware resources with the other users but
isolates the OS or application to avoid changing the end-user
experience.

4. Need of VM
• Isolation from the host operating system
• Easy to stop and start testing
• Quick recovery using snapshots
• VM Appliances are easy to replicate

5. Virtualization
• VM share the centralized server processor, memory & storage.
• Earlier 800 Million unique server is working.
• But now with VM only 60 Million server is doing the same work
of 800 Million server.

6. What is Virtualization
Virtualization is a technology to run multiple same or different
operating systems which is completely isolated from each other .
”Ex: Run both Windows and Linux on the same machine.

7. Terminologies
• Host Operating System:
• The operating system actually running on the hardware
• Together with virtualization layer, it simulates environment for Guest
Operating system.
• Guest Operating System:
• The operating system running in the simulated environment
• E.g., the one we are trying to debug

8. Top 10 VirtualizationTechnology Companies
• VMware
• Citrix
• Oracle
• Microsoft
• Red hat
• Amazon
• Google
• Virtual bridges
• Proxmox
• Parallels

9. INSTALLATION OF
VIRTUAL MACHINE

21. Advantages of VM
• Multiple OS environments can exist simultaneously on the same
machine, isolated from each other.
• Virtual machine can offer an instruction set architecture that differs
from real computer's.
• Easy maintenance, application provisioning, availability and
convenient recovery.

22. Conclusion
• Virtual machines are a number of discrete identical execution environments
on a single computer, each of which runs an operating system.
• This can allow applications written for one OS to be executed on a machine
which runs a different OS which provide a greater level of isolation between
processes than is achieved when running multiple processes on the same
instance of an OS.
