from mint to centOS

OK I need to take some notes on going from linux mint to centOS.

First, I have nothing against linux mint. In my opinion it's the best Desktop OS.

But I needed centOS to learn the RedHat way of doing things on servers.

So I switched.

Now, I tried centOS in Virtualbox first, but found I couldn't use centOS as a guest OS and benefit from the vtx in the processor. centOS had to be the OS installed directly on to the metal.
