Obviously I'm having a bit of fun with a GNU/Hurd VM and the Free BSD one was to see if I could get Qgis running on a different platform other than Linux. This ultimately has failed because I could not map the network share from MainPC. The Win98 VM is not running Windows 98 because I don't have an ISO I can install from. ReactOS is another bit of fun although it does work. And then there are seven VMs running Qgis. There are four stable versions with some apparent duplication at 2.18, and then three different development versions.
