#16404 closed defect (fixed)

vboxsf does not get autoloaded when a mount happens (fs-vboxsf alias missing)

Reported by: hyperair Owned by:
Component: other Version: VirtualBox 5.0.14
Keywords: vboxsf shared folders Cc:
Guest type: Linux Host type: all


When the vboxsf kernel module is not loaded, mounting a shared folder (e.g. mount -t vboxsf foo /media/foo` fails with ENODEV.

The reason for this is that vboxsf lacks the fs-vboxsf alias, which is what the kernel uses to autoload filesystem modules during mount. This can be fixed by adding the following to vboxsf/vfsmod.c:


Alternatively, it can be worked around by adding "alias fs-vboxsf vboxsf" to a file in /etc/modprobe.d.

Please see the attached MIT-licensed patch for a proposed fix.
