VirtualBox 2 is out. VirtualBox is Sun Microsystems’ entry into the Virtual Machine market, and competes against Parallels and VMWare. Unlike the others, it is free and comes in an open source flavour.
Since I have been using Parallels for some time, and VirtualBox is free, I thought I’d give it a spin on my MacBook, using Mac OS X as the host operating system. Parallels is excellent for running Windows Vista (and presumably XP), but its Linux support has been a little lacklustre and the past 2 releases have not supported Ubuntu 8.04 despite being released after Ubuntu has been released.
For version 2, quite a bit of work has gone on to make VirtualBox fit into OS X better, and it shows – though it still feels like a port, it looks very much look a native Mac application and it’s very easy to get going. Since I only have 1 Windows Vista license and I’m already running it in Parallels, I decided to try it with Ubuntu 8.04.
And it seems to work well. Plus, VirtualBox’s ‘Guest Additions’, software for the guest OS which enhances support, work for Ubuntu 8.04 – unlike Parallels Tools which only work for older Ubuntu releases. They also go further; not only do you get dynamic screen sizing (the display area adjusts depending on the virtual machine’s window size), seamless mouse pointer integration and time synchronisation – there’s also clipboard synchronisation and an attempt at desktop integration, which resembles Coherence mode in Parallels, but it works under Linux as well as Windows. However, it’s a bit buggy and I had some rendering issues while trying to use it.
Other down points? There’s no importing from other disk formats – so if you already have virtual machine set up in Parallels you can’t use it straight-away in VirtualBox (although if you can find a tool that converts the disk to the VMDK format you may have some luck). And PowerPC Mac owners are out of luck as VirtualBox is Intel-only, although running an Intel VM on a PowerPC machine would be very slow anyway.
That all being said, VirtualBox is a strong contender, and you can’t argue with free. For many, this will do everything that they demand from its commercial rivals, without costing a penny.
