GNOME

GNOME Boxes integrates perfectly with the GNOME desktop and saves you the trouble of installing Oracle's Virtualbox. You can use GNOME Boxes to install and run Windows, Ubuntu, Mint, openSUSE and many other Linux distributions in separate containers on one computer. The benefit of using GNOME Boxes over Oracle's Virtualbox is that it is easier to set up containers in the first place and there aren't so many fiddly settings.
