Full origin of virtual machine →Frequently Asked Questions
What is the difference between a virtual machine and a container?
A virtual machine carries a full operating system of its own and behaves like a separate computer, which makes it heavier to start and larger to store. A container shares the operating system of the host and packages only the application and the files it depends on, so it is lighter but less isolated.
Why would you run a virtual machine?
Common reasons are running software built for a different operating system, keeping risky or experimental work away from the main system, and dividing one large server into several independent ones that can be created and destroyed easily.
Does a virtual machine slow the computer down?
It uses a share of the host computer's processor, memory and storage while it is running, so the host has less available. Modern processors include features that reduce the overhead considerably, but the resources are still divided between host and guest.
