I just fired up a fresh CentOS 6.4 64-bit VirtualBox instance. The VM / instance built fine and it's working perfect. Now I would like to start getting the VB Guest Additions installed however I read on the Wiki that some distributions ship with their own custom version of GA installed.

My question is:

How can I verify if my new installation of CentOS 6.4 has any trace of VirtualBox GA's installed on it and would it be a problem if I manually installed the official GA package from VirtualBox's site?

If you receive a warning about a previous version form another source while trying to install the guest additions form VirtualBox you would need to remove them prior to installing. Other wise if you try and receive no warning you should be fine. Various ways to check before hand. Use the package manager and search for VirtualBox or virtualbox is probably the easiest unless you know how using the CLI.

Yeah I prefer not to just attempt blindly and get some random conflict error. So your suggestion is simply 'grep' for anything from 'virtualbox'?
