virtual machine - Failed to mount folders in Linux guest (Vagrant) -

i using virtualbox manager (version 4.3.22) & vagrant (version 1.7.2) , have following problem when doing 'vagrant reload'. note i'm using windows 7 professional on desktop machine. (note - can vagrant-ssh box not sure why errors occurring)

i've tried of other solutions other posts in regards installing additional plugins still no joy.

failed mount folders in linux guest. because "vboxsf" file system not available. please verify guest additions installed in guest , can work properly. 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

here 1 important reason why error occurred vagrant up

if use virtual box vagrant's provider, have reinstall 'guest additions' everytime create virtual machine's kernel.

vbguest plugin solution solving issue.

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

first, have install vbguest plugin.

$ vagrant plugin install vagrant-vbguest

and run vagrant

$ vagrant halt

$ vagrant up

or use too

vagrant reload
