Technical advances in machine and system virtualization are creating opportunities for remote learning to provide significantly better support for active education approaches. Students now, in general, have personal computers that are powerful enough to support virtualization of operating systems and networks. As a conse- quence, it is now possible to provide remote learners with a common, standard, virtual laboratory and learn- ing environment, independent of the different types of physical machines on which they work. This greatly enhances the opportunity for producing re-usable teaching materials that are actually re-used. However, con- figuring and installing such virtual laboratories is technically challenging for teachers and students. We report on our experience of building a virtual machine (VM) laboratory for a MOOC on relational databases. The architecture of our virtual machine is described in detail, and we evaluate the benefits of using the Vagrant tool for building and delivering the VM.
