Required: Virtualbox Guest Additions
Before trying to mount/map shared folder you must install Guest Additions (run machine and choose "Devices" -> "Install Guest Additions" from the menu.
Linux guest
If you are running a Linux guest, open a terminal and type:
cd /cdrom
in for instance Ubuntu Lucid, the cd image should mount at /media/<cd name> so that would be
cd /media/<cd name>
then, if you have 32 bit system:
sudo sh VBoxLinuxAdditions-x86.run
or
sudo sh VBoxLinuxAdditions-amd64.run
if you have a 64 bit system. Alternatively simply
./autorun.sh
that should handle the architecture - as well as the privileges - for you Make sure you have the image VBOXADDITIONS mounted as cdrom before installing it. Note: The client OS can not be open when adding share. You will have to reboot the guest machine.
Prepare host
On the host (ubuntu) computer, run
mkdir ~/VirtualBoxShare VBoxManage sharedfolder add "XP" -name "share" -hostpath /home/your/shared/folder/VirtualBoxShare/
Where "XP" is the name of the virtual machine in VirtualBox, and "share" is the name of the share as the guest machine will see it. The hostpath must be a fully-qualified path.
Prepare guest
Windows
On the Windows client, run
net use x: \\vboxsvr\share
Linux
If the client is Linux, you have to mount and connect it to a folder. Run
mount -t vboxfs share mountpoint
For the above command if you get error as
mount: unknown filesystem type 'vboxfs'
Then just change the vboxfs to vboxsf means the command will be
mount -t vboxsf share mountpoint
See Section 4.4 Folder Sharing in the VirtualBox documentation. Note: above will mount folder as owned and writable only by root. If you want the user to be able to use it, mount with the following options
mount -t vboxsf -o uid=1000,gid=1000 share mountpoint
Troubleshooting
/sbin/mount.vboxsf: mounting failed with the error: Protocol error
The above error could be one of the following.
Reinstall Guest additions
Virtualbox Guest Additions have to be reinstalled after some updates. So install them as mentioned on the top of this wiki page.
Reboot
Did you reboot? You have to!
Do NOT use the same name for the mount-point folder. The following example is WRONG:
$ cd Desktop $ sudo mkdir shared $ sudo mount -t vboxsf -o uid=1000,gid=1000 shared shared/ /sbin/mount.vboxsf: mounting failed with the error: Protocol error
The following example is CORRECT:
$ cd Desktop $ sudo mkdir ubuntushared $ sudo mount -t vboxsf -o uid=1000,gid=1000 shared ubuntushared/
As you can see, there is no error now. :-)
