The main reason for me to post this here is to remind our readers to make an upgrade to one of the most recent versions of Virtualbox if your current version is giving some problems.
My VirtualBox on Linux was completely gone, all of a sudden it just stopped working. But then all I needed to do was uninstall it and install again. What happened was that after it got purchased by Sun, the repositories changed so for some reason the software wasn’t cooperating much with me.
Now I can go back to testing some more Linux OSs.
