[Project] Just released: a virtual museum with nearly every OS you can think of...
(virtualosmuseum.org)
The full edition includes everything pre-downloaded and can be used fully offline, whereas the lite edition is much smaller and doesn’t include any disk/tape/etc. images for installations, downloading them the first time an installation is run (which means an internet connection is required to run an installation that hasn’t yet been downloaded). The same guest VM installations are available in both editions, and both editions update packages from the same underlying repository.
Lite Edition: 14GB zipped, 21GB unzipped
For anyone who can't just download 121GB in one go
