Mount shared folder on CentOS in VirtualBox

shared_folder_centos_virtualbox.txt

# The VirtualBox documentation[1] for how to install guest additions 
# for Linux on a virtual host is somewhat messy. So here is what 
# I did to make it work.

# Install the packages required
yum update
yum install gcc kernel-devel make

reboot

# Click: Devices/Install Guest Additions... 

# Mount the ISO image with the guest additions
mkdir /cdrom
mount /dev/cdrom /cdrom

# Install guest additions
/cdrom/VBoxLinuxAdditions.run

# Share a folder from the VirtualBox control panel, giving it a share name.

ls  /media/sf_<share_name>


# You could always mount the directory yourself as well
mkdir /a_folder_name 
mount -t vboxsf the_share_name /a_folder_name

/sbin/mount.vboxsf: mounting failed with the error: No such device

@pius-pworld - I got the same error. If you look at the suggested log to figure out what went wrong /var/log/vboxadd-setup.log you probably will see the message asking you to install libelf-dev, libelf-devel, or elfutils-libelf-devel.

I did install the elfutils-libelf-devel by: yum install elfutils-libelf-devel. After that, the /cdrom/VBoxLinuxAdditions.run worked for me.
