linux更新后，vagrant up fail

vagrant up
VirtualBox is complaining that the kernel module is not loaded. Please
run `VBoxManage --version` or open the VirtualBox GUI to see the error
message which should contain instructions on how to fix this error.
zhang@zhang-OptiPlex-780:~/cf-vagrant-installer$ VBoxManage --version
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (3.2.0-55-generic) or it failed to
         load. Please recompile the kernel module and install it by

           sudo /etc/init.d/vboxdrv setup

         You will not be able to start VMs until this problem is fixed.
4.3.0r89960

第二次了，自动更新linux的软件后，它应该是将内核的版本号也更新了，而新版本的kernel module未加载。因此需要执行sudo /etc/init.d/vboxdrv setup
