Reading the Virtualbox user manual, I finally got [here], which explains how to install Virtualbox Guest Additions on a Linux guest via Command Line.

But it's not clear enough for me (I just started learning some commands). Can someone put down the exact commands you would use to install Virtualbox Guest Additions via CLI? (which includes finding where virtualbox guest additions has been mounted etc.)

... finally this worked for me, should also work for anybody else trying to install Virtualbox Guest Additions on a CentOS (x86_64) virtual server in command line mode.

# yum update
# yum install gcc
# yum install kernel-devel
# yum install bzip2
# mount /dev/scd0 /media/cdrom
# sh /media/cdrom/VBoxLinuxAdditions.run

When the process is complete, reboot the system. That's all.

I do not think there is a need for the reboot here. Just check the vbox* modules are installed under /lib and then run modprobe for each vbox module; make sure the vbox startup scripts at /etc/init.d/vbox* are all (re)started. To just check whether the VBoxAdditions are working, I would start with testing the copy-paste between the source and vmguest. Run VBoxClient-all command and see if it returns anything. If nothing is returned VBox is setup fine. Also, check chkconfig to make sure the vbox startup scripts are properly defined to start at required runlevels. –  Nikhil Mulley Nov 30 '11 at 10:24
You need to yum install make as well –  nic ferrier Feb 6 '12 at 12:23
I try to do the line mount /dev/scd0 /media/cdrom and I get: mount point /media/cdrom does not exist. Is there something I am missing? –  theJerm Oct 31 '12 at 18:46
@theJerm I hope you already figured this out, but for the record: create the mountpoint (just a directory) with sudo mkdir /media/cdrom. –  Anthon Jun 10 '13 at 20:27
On a minimal install of CentOS 6.4 64b the install command was sh /media/cdrom/VBoxLinuxAdditions.run. I also had to install Perl (yum install perl) and create the mount-point (sudo mkdir -p /media/cdrom). –  smholloway Nov 11 '13 at 16:18

This is an old thread but came up in my search for a similar issue. In case anyone else runs into this, the following answer solved it for me:

These steps are a lot better, because they include all of the necessary prerequisites like perl and dkms –  bmaupin Sep 26 '14 at 16:07

After installing the VBOXADDITIONS you might need to do this:

In VirtualBox click View>>Auto Resize Guest Display (Host + G)

because the screen resolution did not work for me until I applied this final configuration to VirtualBox.
