Virtual Box no access to shared folder

English Network/Internet

I am trying out OpenSUSE and have familiarity with Ubuntu (various flavors). I created a share via Virtual Box (like I always do) and I can access it fine on Ubuntu (and others), on Fedora, but cannot access it on OpenSUSE? I took the same steps I normally would and which worked on the others but not on OpenSUSE.

Created the share in Virtual Box:

Booted OpenSUSE and added my user to the vboxsf group and confirmed it was there:

rod@VM-OpenSUSE:~> sudo usermod -a -G vboxsf rod
rod@VM-OpenSUSE:~> id rod
uid=1000(rod) gid=1000(rod) groups=463(vboxsf),1000(rod)

Rebooted OpenSUSE but still cannot access the share.

I note, also, that my user can’t even list contents of /media – something that can be done on Ubuntu and Fedora. (Of course, using sudo I can ‘ls’ the /media contents and see the same thing I do under Ubuntu.)

OpenSUSE

rod@VM-OpenSUSE:~> ls -alR /media/media:

Can someone explain why I cannot access the share I created via Virtual Box? Why I cannot ‘ls’ the contents of /media?
Searching I found this article (https://forums.opensuse.org/showthread.php/502552-Cannot-enable-Virtualbox-shared-folder) but it seemed more of a rant without a real solution.

I had not tried this for a few months, it worked back in 6.1.8. it fails in 6.1.32.

There is a /run/media but no /run/media/username. Is that possibly the reason?

It also does not work in 15.3 any more. It does work in my Windows XP, 10, and 11 machines which have VB extensions from the CD image and not built into like OpenSUSE.

It also works fine in Kali Linux image on the same machine.

I suspect a major bug got introduced with OpenSUSE version.

Automount is what is not working

you can manually mount the share with command replace sharename with the share you setup and /mnt with where you want to mount it.
uid=1000 is the 1st user name and gid=100 is group users on your machine

sudo mount -t vboxsf "sharename" -o uid=1000,gid=100 /mnt

this will mount it as root to /mnt

sudo mount -t vboxsf "sharename" /mnt
