Review: GNOME Boxes
Dumb-proof way to virtualize
This program is very easy to use for anyone, even those who don’t understand much about virtualization, which is honestly great. Other virtualization apps can look complex and daunting to beginners, so it’s very good that GNOME Boxes exists.
For simple use cases, there are no reasons I can think of to not use it. Works out of the box, as intended.
