Hello
I tried out the lite version on Windows.
It is a VirtualBox implementation with a Debian image that has the "Virtual Museum Launcher". This linux application gives you a variety of legacy OSes you can install.
It took me sometime to understand it, but basically you can search the OS/2 on the bottom part of the app.
It will download the OS Virtual image and make it run. On the case of Warp 4, running on Virtualbox, inside a Debian Virtualbox, it was not good.
But it is kind of nice project, currently all images are in English, but who knows, it can grow to have different languages in time. Yes, it is massive.
Regards
