  1. Good Tips – it works. For Centos 7 and for Centos 6 also.

    • Hi JR,
      I have installed one Oracle Linux 6.6 hosted by Windows. I’m student and I used your post to install Guest Additions, just to split my screen in two parts, but after reboot process the Oracle VM VirtualBox is not resizing the screen. Could you please help me to solve this problem?


      • su –
        mkdir /media/vboxguest
        run df -h
        see where areyou seeing your VirtualBoxGuestAdditions media mostly in /media/VirtualBoxGuestAdditions or run/media/root/VirtualBoxGuestAdditions (on RHEL7)
        go to that directory and execute cp / /media/vboxguest/
        yum update kernel*
        yum install gcc kernel-devel kernel-headers dkms make bzip2 perl
        cd /media/vboxguest
        run ./

        no need to do any other step. in my case it worked always and have tried more than 20 times.

  2. Thanks a lot for this post! It was a life-saver for me.
    In certain regards I am forced to use CentOS and I don’t understand why this is so annoying compared to Ubuntu.

  3. Thanks a Lot. Installed GA successfully for Centos 6.5 on VirtualBox with your guidelines.
