Oracle(former Sun) VirtualBox provides virtualization solution without much hassle and requires almost no initial knowledge about virtualization technologies, but it isn’t designed for an enterprise usage. It just lacks the same flexibility and the features of VMWare. Sadly, migration from one application to the other isn’t straightforward. I stumbled upon two good resources on this subject. First guide is somewhat outdated, but it outlines the parts which need to be changed. Second link gave me an insight into the problem and I was able to solve everything else.
