Vagrantがマウントに失敗するときの対処法 ~mounting failed~

内容

Vagrantまわりをいろいろと弄っているとマウントに失敗したという下記に記載の通りのエラー文が出たのでその解決の忘備録

環境

Windows10
VirtulBox 6.0.4r128413
Vagrant 2.2.4
bento/centos-6.8 (virtualbox, 2.3.4)

問題のエラー文

> vagrant up

# 出力されたエラー
Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=500,gid=500 vagrant /vagrant

The error output from the command was:

/sbin/mount.vboxsf: mounting failed with the error: No such device

解決策

  • https://www.task-notes.com/entry/20150714/1436842800

    vagrant-vbguest のプラグインをいれておけば、自分の環境の VirtualBox のバージョンと Box にインストールされている Guest Addition のバージョンが違う場合に、VirtualBox のバージョンに合わせて最新化してくれるというもの

  • 上記参考URLに従い、vagrant-vbgusetというpluginをインストールしてvbguestを実行すれば解決

pluginのインストール

> vagrant plugin install vagrant-vbguest

# 出力結果
Installing the 'vagrant-vbguest' plugin. This can take a few minutes...
Installed the plugin 'vagrant-vbguest (0.19.0)'!

vbguestの実行

> vagrant vbguest
