Open Virtualization Archive (OVA) is a portable Virtual Appliance bundle containing a Virtual Machine. JustBrowsing .ova files are generated from .iso builds and make it easy to test JustBrowsing or distribute across a computer lab.
If all you use your computer for is checking email, social networking, watching cat videos and online shopping, this is the distro for you. Perfect for guests, user privacy in mind with a lock screen and browsing history is always erased on power off. Settings such as display resolution, timezone, browser language, keyboard layout, homepage, and more can be configured from one GUI or via kernel parameters (using boot menu entries or manually)
