Vagrant : インストール2024/05/09

VirtualBox 等の仮想化ソフトウェアのラッパーツール Vagrant をインストールします。
主要な仮想化ソフトウェアには概ね対応していますが、当例では Libvirt インストール済みを前提とします。
[1] Vagrant をインストールしておきます。
[root@dlp ~]#
dnf -y install vagrant
[root@dlp ~]#
systemctl start virtnetworkd
[2] Vagrant の基本操作です。任意の一般ユーザーで利用可能です。
# 仮想マシンイメージをダウンロードして追加
