virtual box4.3.10でdebian系unix仮想マシンの共有フォルダがマウント出来ないバグを踏んだ

bug virtual box debian ubuntu linux vagrant technology

前回Discover Vagrant Boxes | Atlas by HashiCorpはすごい簡単ですよー、みたいな記事あげてたけど、実際にはdebianのbox落として立ち上げるときだけとても困ったバグを踏んだ。
以下にログを書くと

$ vagrant up
(いろいろ省略)
==> default: Checking for guest additions in VM...
==> default: Mounting shared folders...
    default: /vagrant => /Users/kimikimi714/Documents/vagrant/debian-7.4
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

というわけでまたしても共有フォルダがマウントできなかった。3月30日にあげた記事とはまた全然違う原因だった。
この問題を解決したのは以下のリンク。

初めのリンクのタイトルを読むとvagrantに問題があるように書いてあるが実際にはVirtual Box 4.3.10が提供するGuest Additionsに問題がある。また2つ目の記事にはubuntu仮想マシンだと共有フォルダがマウントできないって書いてあるけど、ubuntudebianunixなので実際にはdebianでも起こる問題。

簡単に解決方法を書いておくと

  1. バグが修正されたGuest Additionsをwget https://www.virtualbox.org/download/testcase/VBoxGuestAdditions_4.3.11-93070.isoでダウンロードする。
  2. ホストマシンのGuest Additionsにダウンロードしたものを上書き。macならsudo cp VBoxGuestAdditions_4.3.11-93070.iso /Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.isoでいける。
  3. vagrant-vbguestが入っているなら普通にvagrant upvagrant reloadで共有フォルダがマウントされる。

そのうちVirtual Boxのupdateがくるだろうから、それに合わせてこのバグも修正されると思う。

続きにはどうやってこの問題を解決できるリンクを探し当てたかの経緯を書いておく。

またvboxsfがマウントできてないのかよー。
でもCentOSじゃないからyumではパッケージ管理してないし、そもそもGuest Additionsをインストールするのに必要なカーネルlinux-headers-3.2.0-4-amd64 is already the newest version.を見る限り既に存在しているようだ。

試しにゲストマシンにログインして手動でマウントをさせてみよう。

mount: Protocol error

ん?Protocol error

初めはmount: Protocol errorで検索して、VirtualBox(Ubuntu)で共有フォルダするときの注意。 - Rubellum fly lightとか出てきたけど、 Virtual Boxの「自動マウント」のチェックボックスは初めから外れていたから、これでは解決できなかった。ただ、このリンクに「Ubuntu」という言葉が入っていたので、もしかしてと思いvirtualbox debian vagrant mountでググったら上記2つのリンクが出てきた。
