Please help me with some information on virtual machines. I would be very grateful if you can please explain why people install virtual machines on their computing systems. What is the main purpose of running a virtual machine? What particular tasks are virtual machines efficient at accomplishing? What are the benefits of using a virtual machine?
1) People install virtual machines to test new software, to backup your system when upgrading or making changes to your operating system, also it is installed for disaster recovery and for trying new operating systems.
2) Virtual machines allow the testing of experimental software without fear of causing instability and change in performance of host computer. Also virtual machines can be saved as appliances which help in saving all completed configurations without having to recreate them again which might become too much work if the configurations were complex.
3) the benefits of running a virtual machines are that you can access virus infected information, you can run old applications which cannot run in current operating system, and also you can backup server data.
