=== Option 1 ===
* Become privileged(root user):
su -
* Get the VirtualBox repo installed:
yum clean all
yum update
* Install VirtualBox (along with a few other needed packages)! If you’re having issues here, try installing “kernel-PAE-devel”first.
yum install -y VirtualBox-3.2 dkms gcc
* Add yourself to the “vboxusers” group and fix the SELinux Permissions (just in case):
usermod -G vboxusers -a <yourusername>
* Run, and enjoy!
