vagrant up時に「mount: unknown filesystem type 'vboxsf'」が発生する

概要

  • VagrantでUbuntu15.04のBoxを利用しようとした際に以下の Error が出た
mount: unknown filesystem type 'vboxsf'
  • boxに「VirtualBox Guest Additions」がインストールされていなかったのが原因だった

環境

問題

  • Ubuntu15.04のVagrantboxを取得し、起動しようとしたが、以下のエラーが発生
% mkdir TestDir; cd $_
% vagrant box add ubuntu15.04 https://github.com/kraksoft/vagrant-box-ubuntu/releases/download/15.04/ubuntu-15.04-amd64.box
% vagrant box list

    default: The guest additions on this VM do not match the installed version of
    default: VirtualBox! In most cases this is fine, but in rare cases it can
    default: prevent things such as shared folders from working properly. If you see
    default: shared folder errors, please make sure the guest additions within the
    default: virtual machine match the version of VirtualBox you have installed on
    default: your host and reload your VM.
    default:
    default: Guest Additions Version: 4.3.22_Ubuntu r98236
    default: VirtualBox Version: 5.0
==> default: Mounting shared folders...
    default: /vagrant => /Users/daicho/Work/DevEnv/ubuntu1504/TestDir
Failed to mount folders in Linux guest. This is usually because
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:
mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3` vagrant /vagrant
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` vagrant /vagrant
The error output from the last command was:
stdin: is not a tty
mount: unknown filesystem type 'vboxsf'

原因

  • GuestOS内に「Virtualbox Guest Additions」がない、もしくはバージョンが違う
  • 実際にログインしてみてもコマンドがない
vagrant@vagrant-ubuntu-trusty:/usr/bin$ vboxsf
vboxsf: command not found

解決策

策1) GuestOS内に「Virtualbox Guest Additions」を手動インストールする

  • GuestOSにSSHログインする
% vboxmanage --version                                                                                                                                          [~/Work/DevEnv/ubuntu1504/TestDir]

※当たり前ですが公式ページにもインストール手順書いてありました

策2) Pluginの「vagrant-vbguest」をインストールしておく

vagrant-vbguest」を入れてくと、起動時にホスト側の「GuestAdditions」をゲスト側にインストールしてくれる

  • vagrant-vbguest」をインストールする
% sudo vagrant plugin install vagrant-vbguest
% vagrant vbguest --status
GuestAdditions 5.0.10 running --- OK.
  • 通常通り「vagrant up」すると自動でインストールされる
% vagrant up --provider=virtualbox

まとめ

VirtualBoxのVagrantBoxを作成する際はしっかりとVirtualbox Guest Additionsをいれてあげるのは大事だが、 結局利用するホスト側のバージョンはいろいろなので、プラグイン入れておく。
