Virtualbox is definitely my favorite virtualization tool. Yes, I know there are other, more popular ones, but Virtualbox is free, runs on many platforms, and isn’t clunky to use, like some unnamed others. We all have our preferences, and Virtualbox is definitely mine.
I haven’t had a lot of time to kick the tires yet, but one of the best features I’ve found in the latest, 4.0, version is an easy method to export virtual machines that you’ve built. There were ways to do it before, but now it’s easy.
Once you’ve installed/upgraded to version 4.0, simply choose Export Appliance from the File menu of the Virtualbox Manager. The first one I did took less than 10 minutes from start to finish, all wrapped-up in a single file.
Like I said: good stuff.
