So a couple of things popped up recently which caught my eye and made me think 'hmm, could be really interesting for testers', so I thought I'd just throw a note out about them:
http://blog.pingoured.fr/index.php?post/2014/03/20/Introducing-dgroc - could be interesting to anyone wanting to test a given bit of software over time
http://blog.wikichoon.com/2014/03/snapshot-support-in-virt-manager.html - probably interesting to anyone using virt-manager!
