Installing VirtualBox Guest Addition on CentOS 7 server – no GUI

January 19, 2016 3 comments

I am doing this on

  • VirtualBox 5.0.12
  • Windows 8.1 64 bit Host
  • CentOS 7 server 64 bit guest up to date

Steps

  • Start CentOS 7 guest
  • From the Devices Menu,go to Optical Drives and remove previous CD/DVD using the Remove Disk from VirtualDrive
  • Then click on Devices and select Insert Guest AdditionsCD Image.
  • This will put the Guest addition cd into /dev/cdrom in CentOS
  • SSH into CentOS and mount the cdrom with the command
mount /dev/cdrom /mnt
  • Install required libraries
sudo yum install bzip2 gcc kernel-devel dkms
  • install the guest addition, nox11 is to indicate that we dont have a GUI
bash /mnt/VBoxLinuxAdditions.run --nox11
  • It will install and finally give some messages like below
Verifying archive integrity... All good.

  • Shutdown the CentOS VM and add shared folders and select Auto Mount
  • Start the CentOS VM and the shared folder should be available at /media on CentOS
