Failed to mount folders in Linux guest (Vagrant)

Question

I am using VirtualBox Manager (version 4.3.22) & Vagrant (version 1.7.2) and currently have the following problem when doing a 'vagrant reload'. Note i'm using Windows 7 Professional on my desktop machine. (note - I can vagrant-ssh into the box but not sure why the errors are occurring)

I've tried some of the other solutions from other posts in regards to installing additional plugins but still no joy.

Failed to mount folders in Linux guest. This is usually because
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

Vagrant File :

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|

config.vm.box = "ubuntu/trusty64"

config.vm.network "forwarded_port", guest: 80, host: 2345
config.vm.network "public_network"

config.vm.provision "shell", path: "box/bootstrap.sh"

end

Here is one important reason why error occurred vagrant up

If you use Virtual Box to Vagrant's provider, you have to reinstall 'Guest Additions' that everytime you create virtual machine's kernel.

vbguest plugin is a good solution for solving this issue.

( about vbguest plugin - https://github.com/dotless-de/vagrant-vbguest )

first, you have to install vbguest plugin.

$ vagrant plugin install vagrant-vbguest

and run Vagrant

$ vagrant halt

$ vagrant up

or use too

vagrant reload
