先安装 Master, 在 Master 节点上操作:
1. 安装 yum 源
$ yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm
# 更新一下, 顺便也能对新增的 ovirt yum repo 做一下 makecache
$ yum -y update
2. 安装 ovirt-engine 软件包
$ yum -y install ovirt-engine
3. 安装配置 oVirt Engine

4. 登录验证
5. 接下来添加 Hypervisor Host, 主机添加很简单, 会自动配置, 需要 root 认证
# 首先安装 yum 源, 以及 vdsm 包, vdsm 用于 Master 管理 Hypervisor Host
$ ansible ovirt-host -m yum -a "name=http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm" -v
$ ansible ovirt-host -m yum -a "name=vdsm" -v
下面的 fetch 可以点一下, 来看是否可以连接上
点击 OK 后会弹出 PowerManagement 的配置选项, 不用管, 点 OK, 我们虚拟机也没有电源管理卡
# 在初始化 host 的时候可能会碰到 yum 安装某个软件包的时候因为网速太慢导致 FAIL, 要么科学上网, 要么就多来几次
# 安装完成:
记录的很简单, 安装过程会花上不少时间, 主要还是在软件包的下载上
下一篇接着配置 oVirt 的存储
