I would like to take this time to write about one of my favorite pieces of Open Source software, Virtualbox. If you have a newer PC that was made in the last 5 years with multiple cores, Intel i3, i5, i7 as well as the AMD Athlon X2, Phenom X3 - X4 and now the FX 8Core, then you are most likely able to use virtualbox to run almost any OS available. Have a Windows Vista machine and want to run Ubuntu or CentOS, create a new machine using the Virtuabox Client. Virtualbox has many different virtual machines that you can create from Windows to Linux, BSD to Mac OS/X and even other machines like Haiku.(Open Source BeOS clone)

I have been using this software now for the better part of 3 - 4 years, since before Sun was purchased by Larry Ellison and crew. Oracle has done a good job of supporting this software since the acquisition. Try the software and let me know what you think in the comments section below. I will try and add some basic tutorials in the future on how to use the software and setup you own virtual machines.
