Reason why I chose I full VM (Virtualbox in conjunction with Jenkins CI) is that I also needed to test Windows platforms. AFAIK, the Docker guest systems *must* be unix, possibly only Linux. A big plus of Docker is that the guest systems share resources, so it is a lot lighter to run multiple guest machines. I did hear that nowadays it is possible to use a Windows *host* system. -- https://mail.python.org/mailman/listinfo/python-list
