No there not.
The cable is wired differently to a normal one.
a cross over cable is an ethernet cable. I wouldn't have a clue where you get them as I have always made my own so the length was correct.
Once you do mange to get the machines talking you are going to hit a heap of problems with resource sharing.
I would strongly suggest you make an ISO of the disk and transfer it across using a USB pen drive and then mount it as described in the links I posted.
Also to add an ISO of your music disks is also the way forward as the sound quality is kept as original. It means if later you want to burn a new CD it is exactly the same as the orginal. If you rip to mp3 then burn using that you will loose quality
