I've seem posts on the Internet about similar issues like this one, but I couldn't get it to work.

Host OS: Mac OS X 10.11.1 (El Capitan)
Guest OS: Ubuntu 14.04 LTS
Virtualbox 5.0.8
Vagrant 1.7.4

$ vagrant reload

GuestAdditions seems to be installed (5.0.8) correctly, but not running.

However, the following commands show the right information:

$ vagrant vbguest --status
GuestAdditions 5.0.8 running --- OK.

$ VBoxManage guestproperty get  /VirtualBox/GuestAdd/Version
Value: 5.0.8

I do have other two vagrant VMs running CentOS without any problems.

Any help is appreciated.
