There are two options for install.
* Option 1: # VirtualBox repo. If you are selective or do not install Fedora updates, this is not the option for you. It will result in installation of ALL Fedora updates that your HDA requires.* Option 2: # VirtualBox RPM. This will only install the RPM and any required dependencies or dependency updates your HDA requires. It is much faster and will not force ALL Fedora updates like Option 1.
