Hi. I am a web developer using Mac to develop and Ubuntu Server to deploy. It's a pretty standard setup nowadays. The time came to replace my staging server ( which I keep at my home on a dedicated IP ) and I could not resist the allure of the new Mac Mini Server. So I bought one and tried to do a Ubuntu install and thought I could sell my OSX server license as I have no need of it. I imagine a lot of people not used to Apple's policies might think like this. So how did it go? Bad and then good. As far as I have been able to ascertain, it's impossible to install Ubuntu on a Mac Mini Server ( at least without the additional DVD-ROM drive which I refuse to buy ). What's more, the OSX Server license I bought is not transferable to non-Mac Mini Server computers so I can't really sell it anyway. Even more disturbing... booting from a USB drive seems to be impossible on the thing without hacking the EMI Firmware ( which I refuse to do). My last attempt was to use the shared DVD-ROM drive on my Macbook Pro to install Ubuntu on the thing. No go. You can only boot from the Mac OSX Server disk which comes with the server. Well I got sick of waiting and ended up running Max OSX server as God ( or at least Steve Jobs ) intended. Wow. It's a pretty good OS and I like it... but the whole point of a staging server is to duplicate the live environment so it will never work as good as I need it to work. I was stuck... what to do... then it hit me! VirtualBox to the rescue. I downloaded the free version and installed Ubuntu 8.04 LTS 64 bit with networking in Bridge Mode. Now the VM can be accessed just like any other node on the network ( with its own IP ). In practice its just like having a stand alone Ubuntu server. This may seem obvious to some people but for me it was a revelation. Now both OSX Server and Ubuntu can be accessed independently and due to the 4gbs of ddr memory and fast CPU its faster than I expected and works like a charm. So... that was my very simple solution and now I have the best of both worlds. Also as a note to those who want to know... the Mac Mini Server will boot and reboot just fine without a keyboard and mouse and monitor attached ( as one might expect ) I hope this post helps someone. If I had to do it all over again... I would do it just the same. Nice job Apple.
