I am running VirtualBox OSE in an Ubuntu Lucid host.
The Guest system is also Ubuntu Lucid.

I've set up a Host directory to share with the Guest via VirutulBox's Shared Folders.
This directory is owned by the same user who is running the VM.
The permissions on the directory are: drwxrwxrw

I've installed virtualbox-guest-additions(via Synaptic)

I can't find the shared diretory on the Guest.

I've looked high and low, in /media and /mnt... nothing!

I managed to share the same directory with a Windows Guest, but I am familiar with Windows...

Am I just missing something simple?


Yep, you just need to mount the directory manually. To do that, use mount -t vboxsf SHARENAME /path/to/where/to/mount.

SHARENAME depends on your shared folder, it is the name you entered into VirtualBox Shared Folders dialog.

/path/to/where/to/mount should ideally be inside your user directory (inside VBox). In my case, I use /home/evgeny-vbox/Documents.

EDIT: if you want it to be mounted at boot-time too, add this to your /etc/fstab:

SHARENAME /path/to/where/to/mount vboxsf defaults 0 0

    On the Guest, I tried: ubuntu@Lucid:~$ sudo mount -t vboxsf zap /home/ubuntuzap... I got this error: /sbin/mount.vboxsf: mounting failed with the error: No such device ..... /sbin/mount.vboxsf shows the Link Target as: /usr/lib/VBoxGuestAdditions/mount.vboxsf – Peter.O Oct 13 '10 at 5:38

    How did you install the Guest Additions? Package that you installed provides the ISO, not the additions themselves. Follow this guide: helpdeskgeek.com/linux-tips/… . You might need to use cd /media/VBOX* – evgeny Oct 13 '10 at 5:41
  • Initially I used the .ISO, and then, when that didn't seem to work, I installed the addons via Synaptic.... I'll start afresh, with an new VM, and follow the guide you've posted... and try again. Thanks... – Peter.O Oct 13 '10 at 5:44
  • IIRC the sharename can be chosen in the dialog box of share creation (there is also a command line tool in the host), so it is not necessarily the last name in the path. – enzotib Oct 13 '10 at 5:45
  • Good point, I stand corrected (and edited) – evgeny Oct 13 '10 at 5:48
