I'm running Ubuntu 11.04 (guest) on Windows 7 (host) with the guest additions installed. I have an auto-mount folder that maps to my D: drive on the host which I can access using sudo ls /media/sf_D_DRIVE - however, even when my user (ross) is a member of the vboxsf group I get a permission denied error when attempting to explore it. I have restarted since adding my user to the vboxsf group.
This should work because I am a member of the group (which has rwx rights), so why doesn't it?
ross@panther:~$ ls -l /media

drwxrwx--- 1 root vboxsf 8192 2011-07-03 22:24 sf_D_DRIVE
ross@panther:~$ ls -l /media/sf_D_DRIVE/
ls: cannot open directory /media/sf_D_DRIVE/: Permission denied

I had added my user to the vboxsf group:
sudo usermod -aG vboxsf $(whoami)I did do a restart, but after logging out and in again, I got access! Restarting after this and it still works. Go figure.
7I followed this procedure: Check that your user account is in the vboxsf group. Click on the bird icon, select Users and Groups → Manage Groups → vboxsf → Properties. Your user account should have a checkmark next to it. Check it if it is unchecked. When prompted for a password, enter secret.
Then a restart on the virtual machine (Power of the Machine) and this allowed for the shared folder to work.
1Apparently logging out is insufficient, which seems strange if it was just a matter of being a member of a group. However, this seems to do the trick, without a system reboot:
sudo usermod -aG vboxsf $(whoami)
sudo systemctl restart vboxadd-service.servicewhich suggests that it is not simply a matter of being a member of the appropriate group.
$ sudo apt-get install virtualbox-guest-dkmsGo to your kali linux terminal then run the command below:
sudo usermod -a -G vboxsf (your-kali-username)
sudo chown -R (your-kali-username):users /media/(your-share-folder-name)Below is a sample use:
sudo usermod -a -G vboxsf tahmid
sudo chown -R tahmid:users /media/sf_pen_drive
