Vagrant error : Failed to mount folders in Linux guest

Question

I have some issues with Vagrant shared folders, my base system is Ubuntu 13.10 desktop.

I do not understand why I have this error is something that is not right conf

Answer 1

Install the vagrant-vbguest plugin by running this command:

vagrant plugin install vagrant-vbguest

Answer 2

Just for future reference, this problem happened with me, using Vagrant 1.7.4 and VirtualBox 5.0.10 r104061, when I provisioned a shared folder in / and created a symbolic link to my home folder. Something like this:

/folder
~/folder -> /folder

Apparently, this operation is not allowed by Vagrant due to security purposes and throws the described error.

I solved it by provisioning the desired folder directly to my home directory, such as /home/vagrant/folder.

Answer 3

Try like it:

vagrant plugin install vagrant-vbguest

In Vagrantfile add:

config.vbguest.iso_path = "http://download.virtualbox.org/virtualbox/VERSION/VBoxGuestAdditions_VERSION.iso"
config.vbguest.auto_update = false
config.vbguest.installer_arguments = %w{--nox11 -- --force}

Run:

vagrant vbguest --do install -f -b

vagrant reload

Answer 4

One more step I had to complete after following the first suggestion that kenzie made was to run the mount commands listed in the error message with sudo from the Ubuntu command line [14.04 Server]. After that, everything was good to go!

Answer 5

Update February 2016

This took me hours to solve independently. Yes, this problem does still exist with latest Vagrant and Virtual Box installs:

△  vagrant -v
Vagrant 1.8.1
△  vboxmanage -v
5.0.14r105127

The symptoms for me were messages something like:

Checking for guest additions in VM... The guest additions on this VM do not match the installed version of VirtualBox!

followed by a failure to mount NFS drives.

1). Install the vagrant-vbguest plugin.

Depending on version of Vagrant you are using, issue one of the following commands:

# For vagrant < 1.1.5
$ vagrant gem install vagrant-vbguest

# For vagrant 1.1.5+
$ vagrant plugin install vagrant-vbguest

Next, do vagrant halt, followed by vagrant up - chances are you still have issues.

2). ssh into your guest and setup a soft link to the correct version of Guest Additions (here, 5.0.14).

$ vagrant ssh

$ sudo ln -s /opt/VBoxGuestAdditions-5.0.14/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions
$ exit

$ vagrant reload

You should be all good. By default, the mounted drive on guest is at /vagrant

Final comment:

IF you still have problems related to mounting NFS drives, then here is a workaround that worked for me. I had a vagrantfile with config something like:

Simply remove the mount type information, and slim down the mount_options settings so they work universally. Vagrant will now automatically choose the best synced folder option for your environment.

Answer 6

For me, with VBoxGuestAdditions 5.1.20, the problem was that /sbin/mount.vboxsf pointed to the wrong location.

sudo ln -sf /opt/VBoxGuestAdditions-5.1.20/lib/VBoxGuestAdditions/mount.vboxsf /sbin/mount.vboxsf

fixed it for me
