Installing VirtualBox Guest additions on Ubuntu Guest

1. Mount the cdrom from within the Guest OS, so that the guest additions will be available.

sudo mount /dev/cdrom /mount/cdrom

2. There is a VBoxGuestAdditions.bin script which you will have to execute.

Accessing the Shared Folder. From the VirtualBox Interface, a select folder in your Host Operating System as the folder which you would like to share on the Guest OS.

Remember the name of the shared folder and access it from within the Ubuntu Guest OS like this.

sudo mount -t vboxsf  sharedfoldername mountpoint

Twice I made a mistake of typing vboxfs instead of vboxsf , so be careful with the spelling.
