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=1001,gid=1001 vagrant /vagrant

The error output from the command was:

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

• GuestAdditions seems to be installed (5.1.22) correctly, but not running.となっている
• この状態ではゲストマシン側で共有フォルダの設定(mount)が出来ない

原因

• ホストマシンとゲストマシンのそれぞれのGuestAdditionsのversionが異なっていた
• ホストマシンとゲストマシンのそれぞれのGuestAdditionsのversionが異なる場合、vagrant up時に自動でゲストマシン側がホストマシン側のversionに合わせるように更新される（※上記のエラー内容は何度か再起動を繰り返したものなので更新に関するログは含まれていないです）
• これだけではGuestAdditionsが機能するには十分ではない場合がある
• 自分の場合はゲストマシンのkernelのversionも更新しないと上記のエラーが出るようだった

回避策

• ゲストマシンに入ってkernelのversionの更新する

[vagrant@localhost ~]$ sudo yum update

• ゲストマシンを再起動
