I loved this post, thanks for sharing how you set your virtual labs up! About ten years back we were doing something similar for Micromuse Engineer certifications. We did not have snapshots so we just had to keep copies of the image somewhere we could retrieve when needed. It would take a day to set everything up in a classroom environment, but it was a lot better than it was before. Today, I think we take advantage of exactly how much work has been done to get the class ready for students! Outside of training, this is also a great tool for developers, QA and just playing around with the software. All of this virtualization is what people were doing on the mainframe twenty years ago with LPARs. Funny how things come full circle!!
