Question

OS X（10.11.4）および最新のubuntu/trusty64のバーチャルボックス（5.0.16 r105871）の最新バージョンを使用して、vagrant initのデフォルト構成でVagrant（1.7.4） （v20160323.0.0）。

私のVMにはゲストの追加と一致するバージョンがありますが、共有する/vagrantディレクトリを動作させることができません。 /vagrant/ディレクトリはVM上にありますが、lsを実行すると完全に空です。私はtouchファイルをゲストに/vagrantで表示しますが、私のマシン上のプロジェクトフォルダには同期しません。再起動すると消えます。 VirtualBoxのGUIは、共有フォルダを示しています

    # config.vm.network "forwarded_port", guest: 80, host: 8080

私は問題が何であるかを考え出した - /vagrantディレクトリがマシンに存在していながら、共有フォルダを自動マウント機能がGUIでオンに設定されているにもかかわらずVirtualBoxによって自動的にマウントされておらず、実際にマウントされたことを示すデバッグ出力が表示されます。

sudo mount -t vboxsf vagrant /vagrantを手動で実行すると、問題が手動で解決されます。私はサーバーを起動するための起動スクリプトのプレスタートスクリプトにこの行を挿入します。
