vagrant upするとこんなんなる

vu = vagrant up デス

command

tokifujp:cent7-apache tokifujp$ vu
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Clearing any previously set forwarded ports...
==> default: Clearing any previously set network interfaces...

    default: Adapter 1: nat

==> default: Waiting for machine to boot. This may take a few minutes...
The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in the
'poweroff' state. Please verify everything is configured
properly and try again.

If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since the
GUI often has more helpful error messages than Vagrant can retrieve.
For example, if you're using VirtualBox, run `vagrant up` while the
VirtualBox GUI is open.

The primary issue for this error is that the provider you're using
is not properly configured. This is very rarely a Vagrant issue.

vagrantじゃなくてvirtualboxから起動してみると

あ、あかんヤツやこれ→"VERR_SUPLIB_OWNER_NOT_ROOT"でググろう

原因は/Applications ディレクトリの権限だった

なんやねんApple。

command

tokifujp:~ tokifujp$ ll /

解決方法

sudo chown root /Applicationsしたら治った。
