I haven’t used vagrant + virtualbox for a while and an error shows up when I tried to reuse.
I have googling about it and I found solution.
sudo /Library/StartupItems/VirtualBox/VirtualBox restart
But I got different error when I tried this.
sudo: /Library/StartupItems/VirtualBox/VirtualBox: command not found
And I have checked vagrant version.
vagrant version Installed Version: 1.9.1 Latest Version: 2.2.3
I found my vagrant version is quite old. So I have downloaded new vagrant file and reinstalled. You can download updated version from Vagrantup.com
Also I have upgraded Virtualbox as well.
Then Vagrant start working as before.
$ vagrant up
It’s always good to have things are updated.
