vagrant global-statusで何も出ない
原因
Vagrantをアップデートしたから
If your environment is not showing up, you may have to do a vagrant destroy followed by a vagrant up.
If you just upgraded from a previous version of Vagrant, existing environments will not show up in global-status until they are destroyed and recreated.
対処
VirtualBox上からファイルを削除してvagrant upしなおす
