Wrong shared folder permissions on virtualbox guest

Question

I have a centos guest and I have enabled shared folders. The shared folder is mounted at /media/sf_vbox (witch is annoying as I named the folder vbox on the host).

[duser@centos01 ~]$ ls -l /media
total 2
drwxrwx---. 1 root vboxsf 2048 Feb 22 17:50 sf_vbox
[duser@centos ~]$

The problem is that I can't access it as a normal user and neither chmod or chown works, the ownership and permissions stays the same.

Note that /media/sf_vbox is perfectly accessible as root.

Answer 1

The solution was rather simple as it turned out, append the user who needs access to the group vboxsf and reboot for the permission to take effect.

sudo usermod -a -G vboxsf duser
