VirtualBox: mount.vboxsf: mounting failed with the error: No such device
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
You're using share folders, so you need to install VirtualBox Guest Additions inside your virtual machine to support that feature.
Vagrant
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.
VM
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).
- RHEL:
sudo apt-get update && sudo apt-get install kernel-devel
- CentOS:
sudo yum update && sudo yum -y install kernel-headers kernel-devel
- RHEL:
Install 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 /tmp
sudo mount -o loop /tmp/VBoxGuestAdditions_5.0.16.iso /mnt
sudo 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 vboxsf
Start/restart the service:
- manually:
sudo /opt/VBoxGuestAdditions*/init/vboxadd setup
(addsudo sh -x
to debug) - Debian:
sudo /etc/init.d/vboxadd-service start
- Fedora:
sudo /etc/init.d/vboxdrv setup
- CentOS:
sudo service VBoxService start
- manually:
Building the main Guest Additions module
If 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).
CentOS
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
I am able to resolved this by running below commmand
modprobe -a vboxguest vboxsf vboxvideo
