Some great news came out of Sun Microsystems this week with the release of VirtualBox 3.1.o. This is Sun’s virtualization platform, which has been at the core of many of Sun’s newest technologies. What is great about VirtualBox, aside from being a professional quality hypervisor based virtualization solution, is that it is open source.
According to Sun, the newest major features added are:
The first of these new features, ‘Teleportation’, is HUGE. The ability to migrate a live virtual machine really makes downtime a think of the past and the true multi-platform nature of VirtualBox (Solaris, Linux, Mac and Windows), allows for this migration to take place across operating systems, hardware vendors, processor architectures and even from servers to clients.
Allowing restores from arbitrary snapshots makes for a pseudo revision control system for virtual machines. This is a definitely a feature that will come in handy for developers and testers.
2D video acceleration will definitely help on the virtual desktop front. Flexible storage attachments allow users to more accurately mimic physical hardware for certain systems, and changing a network attachment type on-the-fly can help with virtual network testing. The rewrite of USB drivers for OpenSolaris brings the platform closer to plug and play functionality.
A performance increase for PAE and AMD64 guests is always a welcome thing as is the foray into EFI support. Naturally, the paravirtualized network driver will drastically increase networking performance for guests.
I would say that Sun has made some major advancements overall in their flagship virtualization platform. Having used VirtualBox on several machines with Unix, Linux, Mac and Windows in my lab, I can definitely attest to the speed and usability of the platform. The added ability to migrate my virtual machines across all of my hosts is a very welcome addition. Paired with SunRay Software 5, I can see the newest release of VirtualBox serving as a solid foundation for a Desktop VDI platform.
