突然vagrant upが失敗するようになるやつ

エラー内容

/vagrant

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

原因

hostOSとguestOSのバージョンが一致しない

vbguestプラグインをインストール

vagrant plugin install vagrant-vbguest

バージョン情報を確認

vagrant vbguest --status

[default] GuestAdditions versions on your host (5.2.4) and guest (4.3.30) do not match.

上記の場合、GuestOSのバージョンが古いことが確認できる
