oVirt 是一个 开源分布式虚拟化解决方案，旨在管理您的整个企业基础架构。 oVirt 使用受信任的 KVM 管理程序 并建立在其他几个社区项目的基础上，包括 libvirt、Gluster、PatternFly 和 Ansible。
在这篇文章中，我将向您展示 如何在 CentOS 7 上安装 oVirt. 所以，让我们开始吧。
安装 oVirt 引擎包
首先，您必须在 CentOS 7 上添加 oVirt 软件包存储库。为此，请运行以下命令：
# sudo yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
现在，按 和 然后按 Enter.
现在，您必须更新 CentOS 7 操作系统的所有软件包。 为此，请运行以下命令：
# yum update
笔记： 如果任何与内核相关的软件包已更新，请重新启动机器。 运行以下命令以 安装 o虚拟引擎 包和依赖项。
# yum install ovirt-engine
如您所见，将从 Internet 下载 498 MB 的软件包。 现在，按 y 然后按 。
现在，按 和 然后按 Enter 接受 CentOS SIG 虚拟化、存储、OpsTools 和 SCLo 存储库的 GPG 密钥。
配置oVirt
运行 engine-setup 命令开始配置 oVirt 引擎：
# engine-setup

配置防火墙
为了能够访问 oVirt 基于 Web 的管理界面，您必须打开 HTTP 和 HTTPS 端口。 您可以在 CentOS 7 上使用 firewalld 轻松完成。
要打开 HTTP 端口，请运行以下命令：
# firewall-cmd --add-service=http --permanent
要打开 HTTPS 端口，请运行以下命令：
# sudo firewall-cmd --add-service=https --permanent
现在，使用以下命令重新加载 firewalld 守护进程：
# firewall-cmd --reload
此时防火墙配置正确。
访问oVirt管理界面
打开 Web 浏览器并输入 URL：
https://ovirtengine.example.com
或者
https://IP_地址
根据您的设置替换域名或 IP 地址。
单击管理员门户。
Enter 用户名为 ‘admin‘ 和 我们在安装和配置文件中提到的内部密码.
登录后，您应该会看到oVirt 的管理界面。 从这里，您可以以图形方式管理 oVirt。 您还可以从这里创建虚拟机。
所以，这就是您在 CentOS 7 上安装 oVirt 的方法。感谢您阅读本文。
