I'm using VirtualBox with OS X as host and CentOS on the guest VM.
In OS X I created folder myfolder, added it as shared folder to the VM, turned on the VM, in CentOS created folder /home/user/myfolder and typing:
sudo mount -t vboxsf myfolder /home/user/myfolder
and have output:
/sbin/mount.vboxsf: mounting failed with the error: No such device
What I'm doing wrong?
UPDATED:
Guest Additions installed.
This was resolved by:
yum install gcc kernel-devel make
workaround is here: https://gist.github.com/larsar/1687725
uname -r dkms –
Bernal kernels-headers was not enough, but kernel-devel helped! @cstroe: uname -r should be in $( ) - see @Dispraise answer. –

Ldopa 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 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
/sbin/mount.vboxsf: mounting failed with the error: No such device. After running the above and restarting the system, my shared folders appeared as they did before upgrading.. thanks! –
Liquesce sudo ./vboxadd setup, you can do sudo ./vboxadd stop. Not sure if it's still necessary, but I'm guessing that's what that sentence means. –
Briony yum and then run yum install gcc kernel-devel make followed by the above commands. Worked for me. –
Chamkis VirtualBox Guest Additions: Kernel headers not found for target kernel 3.16.0-11-amd64. Please install them..., install linux-headers-3.16.0-11. (Replace by your kernel version.) –
Conversable mount.vboxsf: mounting failed with the error: No such device, remove some files using commands ( rm -r not-important-folder ), and then do as mentioned in this answer! Restart and voila! It worked perfectly for me! Edit and expand your partition before shutting down again. –
Anthropocentric You're using share folders, so you need to install VirtualBox Guest Additions inside your virtual machine to support that feature.
If you're using Vagrant (OS X: brew cask install vagrant), run:
vagrant plugin install vagrant-vbguest
vagrant vbguest
In case it fails, check the logs, e.g.
vagrant ssh -c "cat /var/log/vboxadd-install.log"
Maybe you're just missing the kernel header files.
Inside VM, you should install Guest Additions, kernel headers and start the service and double check if kernel extension is running.
This depends on the guest operating system, so here are brief steps:
Install kernel include headers (required by VBoxLinuxAdditions).
sudo apt-get update && sudo apt-get install kernel-develsudo yum update && sudo yum -y install kernel-headers kernel-develInstall Guest Additions (this depends on the operating system).
Ubuntu: sudo apt-get -y install dkms build-essential linux-headers-$(uname -r) virtualbox-guest-additions-iso
If you can't find it, check by aptitude search virtualbox.
Debian: sudo apt-get -y install build-essential module-assistant virtualbox-ose-guest-utils
If you can't find it, check by dpkg -l | grep virtualbox.
manually by downloading the iso file inside VM (e.g. wget) and installing it, e.g.
wget http://download.virtualbox.org/virtualbox/5.0.16/VBoxGuestAdditions_5.0.16.iso -P /tmpsudo mount -o loop /tmp/VBoxGuestAdditions_5.0.16.iso /mntsudo sh -x /mnt/VBoxLinuxAdditions.run # --keep
Extra debug: cd ~/install && sh -x ./install.sh /mnt/VBoxLinuxAdditions.run
Double check that kernel extensions are up and running:
sudo modprobe vboxsfStart/restart the service:
sudo /opt/VBoxGuestAdditions*/init/vboxadd setup (add sudo sh -x to debug)sudo /etc/init.d/vboxadd-service startsudo /etc/init.d/vboxdrv setupsudo service VBoxService startIf above didn't work, here are more sophisticated steps to fix it. This assumes that you've already VBoxGuestAdditions installed (as shown above).
The most common reason why mounting shared folder doesn't work may related to building Guest Additions module which failed. If in /var/log/vboxadd-install.log you've the following error:
The headers for the current running kernel were not found.
this means either you didn't install kernel sources, or they cannot be found.
If you installed them already as instructed above, run this command:
$ sudo sh -x /opt/VBoxGuestAdditions-5.0.16/init/vboxadd setup 2>&1 | grep KERN
+ KERN_VER=2.6.32-573.18.1.el6.x86_64
+ KERN_DIR=/lib/modules/2.6.32-573.18.1.el6.x86_64/build
So basically vboxadd script is expecting your kernel sources to be available at the following dir:
ls -la /lib/modules/$(uname -r)/build
Check if the kernel dir exists (symbolic link points to the existing folder). If it's not, please install them to the right folder (e.g. in /usr/src/kernels).
So vboxadd script can enter your kernel source directory and run make kernelrelease, get the value and compare with your current kernel version.
Here is the logic:
KERN_VER=`uname -r`
KERN_DIR="/lib/modules/$KERN_VER/build"
if [ -d "$KERN_DIR" ]; then
KERN_REL=`make -sC $KERN_DIR --no-print-directory kernelrelease 2>/dev/null || true`
if [ -z "$KERN_REL" -o "x$KERN_REL" = "x$KERN_VER" ]; then
return 0
fi
fi
If the kernel version doesn't match with the sources, maybe you've to upgrade your Linux kernel (in case the sources are newer than your kernel).
Try:
vagrant plugin install vagrant-vbguest vagrant vbgues
If won't work, try the following manual steps for CentOS:
$ sudo yum update
$ sudo yum install kernel-$(uname -r) kernel-devel kernel-headers # or: reinstall
$ rpm -qf /lib/modules/$(uname -r)/build
kernel-2.6.32-573.18.1.el6.x86_64
$ ls -la /lib/modules/$(uname -r)/build
$ sudo reboot # and re-login
$ sudo ln -sv /usr/src/kernels/$(uname -r) /lib/modules/$(uname -r)/build
$ sudo /opt/VBoxGuestAdditions-*/init/vboxadd setup
vagrant plugin install vagrant-vbguest vagrant vbguest works also on centos 7 and resolved the issue. Thanks –
Bloodline I am able to resolved this by running below commmand
modprobe -a vboxguest vboxsf vboxvideo
vboxsf (VirtualBox Shared Folders) is what's needed here. You can list these 3 files one per line in a file in /etc/modules-load.d/ (call it maybe virtualbox.conf) to make this change persist through reboots. –
Touched 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/

apt-get install linux-headers-virtual helped with Lubuntu 15.04 on VirtualBox –
Partitive This was the only solution what worked for me:
Install Vagrant plugin: vagrant-vbguest, which can keep your VirtualBox Guest Additions up to date.
vagrant plugin install vagrant-vbguest

Ldopa Shared folder was earlier working for me but all f sudden it stopped working (Virualbox - host was Windows 7, Guest was OpenSuSe)
modprobe -a vboxguest vboxsf vboxvideo
then
mount -t vboxsf testsf /opt/tsf (testsf was the folder in Windows C drive which was added in Virtualbox shared folder --- and /opt/tsf is the folder in OpenSuse
My host is Windows10 my VM guest is ubuntu build by vagrant. This worked for me:
vagrant plugin install vagrant-winnfsd
The solution for me was to update guest additions
(click Devices -> Insert Guest Additions CD image)
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.
I am running VirtualBox 5.1.20, and had a similar issue. Here is a url to where I found the fix, and the fix I implemented:
# https://dsin.wordpress.com/2016/08/17/ubuntu-wrong-fs-type-bad-option-bad-superblock/
if [ "5.1.20" == "${VBOXVER}" ]; then
rm /sbin/mount.vboxsf
ln -s /usr/lib/VBoxGuestAdditions/mount.vboxsf /sbin/mount.vboxsf
fi
The link had something similar to /usr/lib/VBoxGuestAdditions/other/mount.vboxsf, rather than what I have in the script excerpt.
For a build script I use in vagrant for the additions:
https://github.com/rburkholder/vagrant/blob/master/scripts/additions.sh
Seems to be a fix at https://www.virtualbox.org/ticket/16670
For me, on a mac, it turned out I had an old VirtualBox image stored on my machine that didn't have metadata, so it wasn't being updated to the latest version.
That old image had an older version of the vbguest plugin installed in it, which the newer vbguest plugin on my machine couldn't work with.
So to fix it, I just removed the image that my Vagrant was based on, and then Vagrant downloaded the newer version and it worked fine.
# Remove an old version of the virtual box image that my vagrant was using
$ vagrant box remove centos/7
You can find out which boxes you have cached on your machine by running:
$ vagrant box list
I had also upgraded my vbguest plugin in my earlier attempts at getting this to work, using the following process, but I don't think this helped. FYI !
# Get rid of old plugins
vagrant plugin expunge
# Globally install the latest version of the vbguest plugin`
vagrant plugin install vagrant-vbguest
If you find bring the box fails on guest addtions, you can try doing the following to ensure the plugins install correctly. This downloads the latest based image for your system (for me CentOS), and may resolve the issue (it did for me!)
$ vagrant box update
There can be errors/incorrect approach in two scenarios. Check both of it and figure it out
SCENARIO 1 :
Once you are running the VBoxLinuxAdditions.run or VBoxSolarisAdditions.pkg or VBoxWindowsAdditions.exe , check if all the modules are getting installed properly.
1.1.a. In case of VBoxLinuxAdditions, if
Building the VirtualBox Guest Additions kernel modules gets failed,
check the log file in /var/log/vboxadd-install.log . If the error is due to kernel version update your kernel and reboot the vm. In case of fedora,
1.1.b. yum update kernel*
1.1.c. reboot
1.2. If nothing gets failed, then all is fine. You are already having the expected kernel version
SCENARIO 2 :
If the VBoxGuestAdditions is installed (check for a folder /opt/VBoxGuestAdditions-* is present .... * represents version) you need to start it before mounting.
2.1. cd /opt/VBoxGuestAdditions-*/init && ./vboxadd start
You need to specify the user id and group id of your vm user as options to the mount command.
2.2.a. Getting uid and gid of a user:
id -u <'user'>
id -g <'user'>
2.2.b. Setting uid and gid in options of mount command:
mount -t vboxsf -o uid=x,gid=x shared_folder_name guest_folder
On Ubuntu this worked:
sudo apt-get install build-essential linux-headers-`uname -r` dkms
Had the same issue with VirtualBox 5.0.16/rXXX
Installed latest VirtualBox 5.0.18 and installed latest Vagrant 1.9.3, issue went toodles.
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
I have similar issue, check header if it's not match then run below command
CentOS: sudo yum update && sudo yum -y install kernel-headers kernel-devel
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).
An update did the trick for me !
$ vagrant box update
$ vagrant plugin install vagrant-vbguest
Below two commands works for me.
vagrant ssh
sudo mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant
Okay everyone is missing a basic fact.
mkdir /test - Makes sub directory in current directory.
sudo mkdir /test - Make directory in Root.
So if your shared directory name is shared and you do the following:
mkdir /test
sudo mount -t vboxsf shared /test
It generates this error:
sbin/mount.vboxsf: mounting failed with the error: No such file or directory
Because the directory is in the wrong place! Yes that's what this error is saying. The error is not saying reload the VBOX guest options.
But if you do this:
sudo mkdir ~/test
sudo mount -t vboxsf shared ~/test
Then it works fine.
It really amazes me how many people suggest reloading the Vbox guest additions to solve this error or writing a complex program to solve a directory created in the wrong place.
mkdir /test will create the directory /test in /. sudo mkdir /test will create the same directory, but owned by root rather than the current user. –
