Version 3.1.0 also adds a Teleportation (aka live migration) feature that lets you migrate a live VM session from one host to another. Also, VM states can now be restored from arbitrary snapshots instead of only the last one, and new snapshots can be taken from other snapshots as well.
Virtual appliances are one or more virtual machines that are pre-installed and configured so they can be shared, published and distributed. VirtualBox 2.2 software enables users to build virtual machines or appliances and e export them from a development environment and import them into a production environment. Support for OVF also helps to ensure VirtualBox 31.0 software is interoperable with other technologies that follow the standard.
VirtualBox software is free of charge for personal use. For wider deployments within an organization enterprise subscriptions are also available, starting at US$30 per user per year, which includes 24/7 premium support from Sun's technical team. Discounts are available based on volume.
