oVirt 是 開源分佈式虛擬化解決方案旨在管理整個企業基礎架構。 oVirt 使用你可以信任的東西 KVM 管理程序 它還基於其他幾個社區項目，例如 libvirt、Gluster、PatternFly 和 Ansible。
我會在這篇文章中告訴你 如何在 CentOS 7 上安裝 oVirt..所以讓我們開始吧。
安裝 oVirt 引擎包
首先，您需要將 oVirt 軟件包存儲庫添加到 CentOS7。為此，請運行以下命令：
# sudo yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
現在按 什麼時候 然後按 進來..
接下來，您需要更新 CentOS 7 操作系統的所有軟件包。為此，請運行以下命令：
# yum update
筆記： 如果內核相關的包已經更新，重啟機器。運行以下命令 安裝 哦哦虛擬引擎 包和依賴項。
# yum install ovirt-engine
可以看到，498MB的包是從網上下載的。現在按 y，然後按。
現在按 什麼時候 然後按 進來 接受 CentOS SIG 虛擬化、存儲、OpsTools 和 SCLo 存儲庫的 GPG 密鑰。
配置oVirt
運行 engine-setup 命令開始配置 oVirt 引擎。
# engine-setup
推 進來 配置引擎。

配置防火牆
您必須打開 HTTP 和 HTTPS 端口才能訪問 oVirt 基於 Web 的管理界面。 可以使用 CentOS7 的 firewalld 輕鬆執行。
要打開 HTTP 端口，請運行以下命令：
# firewall-cmd --add-service=http --permanent
要打開 HTTPS 端口，請運行以下命令：
# sudo firewall-cmd --add-service=https --permanent
現在使用以下命令重新加載 firewalld 守護進程：
# firewall-cmd --reload
此時防火牆配置正確。
訪問oVirt管理界面
打開網絡瀏覽器並輸入 URL。
https://ovirtengine.example.com
還
https: // IP地址
根據您的設置替換域名或 IP 地址。
單擊管理員門戶。
請輸入您的用戶名’行政人員‘ 什麼時候 安裝和配置文件中提到的內部密碼..
登錄後會看到oVirt的管理界面。您可以從這里以圖形方式管理 oVirt。您還可以從此處創建虛擬機。
這就是在 CentOS 7 上安裝 oVirt 的方法。感謝您閱讀本文。
