迷走と可用性のある並列プロビジョニング
ので、Vagrant + Libvirtをインストールした後、いくつかのVMSを並列に実行することができます.
このテストのために、Oracle Linuxボックスを使用します.
最初のステップは、Oracle Linuxのボックスを取得し、VMの作成がうまく動作していることを確認する簡単なテストを行うことです.
私はちょうどhere(良いガイドと同様に迷宮+ libvirt実行を得るために)同様の手順に従ったが、現在“https://oracle.github.io/vagrant-projects/boxes/oraclelinux”であるol 8ボックスのURLを変更する必要がありました.

あなたが何かファミリを見るならば、私がちょうど違法なウェブサイトから一般的なものを使うので、あります:Ansible Provisioner
これは私たちのGrarantfileです(それぞれのオプションについてのコメントを追加しました).
