VM CentOS 7（Vagrant / Virtualbox）へのパテ接続の問題

Vagrant（2.2.3）とVirtual Box（5.2.24）を使用して、Windows 10でこのようにVM CentOS7を作成しました（このガイドラインに従って...）。https://blog.centos.org/2019/02/updated-centos-vagrant-images-available-v1901-01/)

vagrant init centos/7
vagrant up

すべてが正常です

その後、ゲストを追加する（rif。https://github.com/dotless-de/vagrant-vbguest）、だから

vagrant plugin install vagrant-vbguest

私の最終結果Vagrantfileは次のとおりです。

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.network "private_network", ip: "192.168.33.10"
  config.vm.synced_folder ".", "/vagrant", type: "virtualbox"

  config.vm.provider "virtualbox" do |vb|
     vb.memory = "4096"
     vb.name = "Test"
   end
end

vagrant upうまく走る

VMが起動しますが、IPアドレス（192.168.33.10）を使用してPutty（ポート22のSSH）を介して接続しようとすると、次のエラーが発生します。

私は何が間違っていましたか？
