vagrant : Failed to mount folders in Linux guest, “vboxsf” file system is not available?

问题

I have VirtualBox 4.3.10 and Vagrant 1.4.3 installed on my Ubuntu 14.04 64 bit Desktop.

Earlier, worked with vagrant technology but this time, multiple issue. Let me describe what I have done

clone private git to local system /opt/lampp/htdocs/{project} : done
root@desktop:/opt/lampp/htdocs/{project}$ vagrant up

gives message on terminal while execution

GuestAdditions versions on your host (4.3.10) and guest (4.2.0) do not match.

command completed with below message

Failed to mount folders in Linux guest. This is usually beacuse the "vboxsf" file system is not available. Please verify that the guest additions are properly installed in the guest and can work properly. The command attempted was:

...

I understand this is version difference.

check vagrant vbguest --status

GuestAdditions 4.3.10 running --- OK.
Open browser and run with http://192.168.0.33 (mentioned on README.md file of private git repo) but it didn't work.

UPDATE

Installed vagrant-vbguest as suggested here

$:sudo vagrant plugin install vagrant-vbguest

Installed the plugin 'vagrant-vbguest (0.10.0)'!

By doing this,message of version difference of GuestAdditions described in 2. is gone

restart vagrant halt and then vagrant up

Failed to mount folders in Linux guest. This is usually beacuse the "vboxsf" file system is not available. Please verify that the guest additions are properly installed in the guest and can work properly. The command attempted was:

    mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3` /vagrant /vagrant
    mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` /vagrant /vagrant

Do I need to change anything in local vagrantfile or change vagrant version or something else?

Some say it is a bug whilesome gives solution for ubuntu < 14.04

Kindly suggest the solution hints and how to fix this issue?

回答1:

 vagrant plugin install vagrant-vbguest

worked well for me (Virtual Box 5.0.22, Vagrant 1.8.4). It took muck longer to provision initially because the plugin downloaded gcc and a bunch of other tools before linking the guest additions .iso to the correct place.

回答2:

Apparently there is a bug in the VirtualBox Guest Additions 4.3.10 installer: https://www.virtualbox.org/ticket/12879

There seems to be a simple workaround to this, by creating a symbolic link within Vagrant-VM:

sudo ln -s /opt/VBoxGuestAdditions-4.3.10/lib/VBoxGuestAdditions \
/usr/lib/VBoxGuestAdditions

You could add this to your provisioning configuration to make sure you don't hit the bug again:

NEWEST_VBOXGUESTADDITIONS_DIR=`find /opt/ -maxdepth 1 -mindepth 1 -name "VBoxGuestAdditions-*" | tail -n 1`;
if [[ ! -d "/usr/lib/VBoxGuestAdditions" && -n "$NEWEST_VBOXGUESTADDITIONS_DIR" ]];
then
    ln -s ${NEWEST_VBOXGUESTADDITIONS_DIR}/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions
fi

回答3:

This line of code in "Vagrantfile" was the solution for me:

config.vm.synced_folder "./", "/vagrant", id: "vagrant-root", type: "nfs"

回答4:

In my case, this error was fixed by rebuilding the kernel on the guest machine with sudo service vboxadd setup.
