Why can't I access a shared folder from within my Virtualbox machine?

I have Ubuntu 14.04 as my host system, and then on Virtualbox, I have Lubuntu 14.04.

I am trying to share a folder on my host system so that my guest system can write files to it. I've followed instructions as best I can, installed the Virtualbox guest additions. I've got to the point where I've added the shared folder in the Devices interface:

shared folder

However, even after rebooting, I can't find the folder anywhere in my guest system.

How do I get my shared folder to actually show up in my guest Lubuntu machine?

You have to mount your folder on your VM.

First you need to install Guest Additions (although I already did this during the installation).

Start your VM

Devices > Insert Guest Additions CD image...

I had to manually mount the CD: sudo mount /dev/cdrom /media/cdrom

Install the necessary packages: sudo apt-get install make gcc linux-headers-$(uname -r)

Install the Guest Additions: sudo /media/cdrom/VBoxLinuxAdditions.run

Now you can mount your share using:

mkdir ~/new

sudo mount -t vboxsf New ~/new

Where New is the name of your shared folder.

Now you can access the shared folder at ~/new.

Note: this is not permanent. To permanently mount your folder you should add the following line to /etc/fstab (sudo nano /etc/fstab):

New /home/user/new vboxsf defaults 0 0

Obviously you should replace user in /home/user/new by your own username.
