I see threads on sharing folders from ubunto host to windoze guest in Sun VBox but I need to go the other way.

I have a guest Ubuntu 8.10 OS running under a Windows XP SP3 host. I'm using a Compaq 6910p laptop and I have Sun VBox 2.2.2 installed on a 250Gb FAT32 USB external drive, and also have the ubuntu virtual machine on the USB HD. I installed the VBoxGuestAdditions.iso. I can add the USB HD shared folder (called U:SunVbx/Shared) using the 'Devices' button in the virtual machine. I put it under 'machine folders' as permanent and I have all permissions. I can't see any of the files I put into that folder from XP. The folders are already created, both in windows (U:SunVbx/Shared) and in guest Ubuntu (/home/george/Shared)

I tried opening a terminal window and typing:

sudo mount -t vboxsf U:SunVbx/Shared /home/george/

but I get an error that says:

/sbin/mount.vboxsf: mounting failed with the error: Protocol error

Any ideas for what I might be doing wrong?

In the Virtualbox settings, where you set up the shared folder, it is given a name which is all i think you need in the first part of the command (eg i have my host's /media/Storage/Music shared and the share name is just Music). Then just create the mount point in the guest as you have done, and this command works for me...sudo mount.vboxsf Music /home/ben/Music

Thank you! It worked just fine, following your suggested command.

One more question .. do I have to do this every time I start the virtual machine? I just restarted ubuntu VM and had to type this command in again. I could do a shell or something, but is there any way to make this permanent? I selected permanent when I defined the shared file, but it doesn't seem as permanent as I would have hoped :)

nice hat BTW ..

nice hat BTW ..You can add a line to /etc/fstab in the guest to mount it automatically. It would be something like...Music /home/ben/Music vboxsf defaults 0 0This is definitely possible, but my line above may have an error.
