VirtualBox: mount.vboxsf: mounting failed with the error: No such device [closed]

Answer 1

An update did the trick for me !

$ vagrant box update
$ vagrant plugin install vagrant-vbguest 

Answer 2

In addition to @Mats answer, I'm adding some more info (it helped me on Debian 8).

My shared folder/clipboard stopped to work for some reason (probably due to a patch installation on my virtual machine).

sudo mount -t vboxsf Shared_Folder ~/SF/

Gave me following result:

VirtualBox: mount.vboxsf: mounting failed with the error: No such device

The solution for me was to stop vboxadd and do a setup after that:

cd /opt/VBoxGuestAdditions-*/init 
sudo ./vboxadd setup

At this point, if you still get the following error:

No such device. The Guest Additions installation may have failed. The error has been logged in /var/log/vboxadd-install.log

You need to install linux headers:

apt-get install linux-headers-$(uname -r)

then you can install Guest Additions:

sh /media/cdrom/VBoxLinuxAdditions.run --nox11

and restart your Linux by:

reboot

then you will be able to mount your shared folder!

mount -t vboxsf Shared_Folder ~/SF/

Answer 3

I added as root user

/etc/rc.d/rc.local 
/root/mount-vboxsf.sh

then

chmod +x /etc/rc.d/rc.local

and the sample script /root/mount-vboxsf.sh (set your own the uid and gid options)

modprobe -a vboxguest vboxsf vboxvideo
mount -t vboxsf NAME_SHARED_DIRECTORY /media/sf_NAME_SHARED_DIRECTORY -o rw,uid=0,gid=0

you need add

chmod + /root/mount-vboxsf.sh

Answer 4

If you're on Debian:

1) remove all installed package through Virtualbox Guest Additions ISO file:

sh /media/cdrom/VBoxLinuxAdditions.run uninstall

2) install Virtualbox packages:

apt-get install build-essential module-assistant virtualbox-guest-dkms virtualbox-guest-utils

Note that even with modprobe vboxsf returning nothing (so the module is correctly loaded), the vboxsf.so will call an executable named mount.vboxsf, which is provided by virtualbox-guest-utils. Ignoring this one will prevent you from understanding the real cause of the error.

strace mount /your-directory was a great help (No such file or directory on /sbin/mount.vboxsf).

Answer 5

I am able to resolved this by running below commmand

modprobe -a vboxguest vboxsf vboxvideo

Answer 6

I also had a working system that suddenly stopped working with the described error.

After furtling around in my /lib/modules it would appear that the vboxvfs module is no more. Instead modprobe vboxsf was the required incantation to get things restarted.

Not sure when that change ocurred, but it caught me out.
