Although I have been a huge fan of VMWare Server I’m not apposed to alternatives. I’ve tried VirtualBox in the past with very little luck due to the Host Networking issues. However, it appears in the latest 2.1 version they have greatly improved on the networking. When I found out the new version had been released I was quick to download the pre-compiled version, which falls under the VirtualBox Personal Use and Evaluation License (PUEL). The license doesn’t matter to me because I mainly use it just for testing and at the School which is completely under the PUEL.
Host Networking worked without a hitch on a Windows XP Professional SP3 host as well as my Ubuntu Intrepid Ibex 8.10 setups. I think this product has finally, truely, entered the game! I’m sure it will still take some time for the Open Source Edition to enter the Repos for Ubuntu. But I expect to see great things from this.
