Virtual Box Manager > CentOS > Settings >

• Inside Storage make sure that the VBoxGuestEditions.iso is loaded on the optical drive
• Inside Shared Folders configure your shared folder structure from the host OS to the guest OS

mkdir /mnt/cdrom
sudo mount /dev/cdrom /mnt/cdrom

# Red Hat Package Manager
# rpm --upgrade --hash --verbose PACKAGE_NAME
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# or
# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

# Yellow dog updater for CentOS
yum install gcc kernel-devel kernel-headers dkms make bzip2 perl

# uname -r, --kernel-release
# @return: kernel release
KERN_DIR=/usr/src/kernels/`uname -r`

export KERN_DIR

cd /mnt/cdrom
sudo ./VBoxLinuxAdditions.run

shutdown -r 0

Now you can use VBoxControl command:

VBoxControl sharedfolder list
VBoxControl --help
