{{Note|This comparison doesn't include Docker, because Docker is not a virtualization solution. It automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating-system-level virtualization.<ref>[https://en.wikipedia.org/wiki/Docker_(software) Wikipedia article about Docker]</ref>}}
