Stderr: VBoxManage.exe: error: Could not find a controller named 'SATA Controller' の解消方法

以下のような設定で vagrant up　をしたら、タイトルのエラーが出来ました。
 ["storageattach", "5cbed0f4-9370-4603-8da8-f02b7f943cad", "--storagectl", "SATA Controller", "--port", "1", "--device", "0", "--type", "hdd", "--medium", "010node.com.vdi"]



解決手順は以下の通りです。
 １、まず　VirtualBoxの設定画面で、「新しいストレージコントローラーを追加委します。」からSATAコントローラーを追加する

　

 

２、次に、 設定ファイルの「 "--storagectl", "SATA Controller"」を「 "--storagectl", "SATA"」に変更する。

　SATA Controllerの「名前」のところに、名前は「SATA」となっているので、それに合わせる必要。
