2.4.1. Red Hat Virtualization Guest Agents and Drivers

Oivrt guest agents 为Linux和Windows虚拟机提供了附加信息和功能,其中最核心的包括监控虚拟机资源使用和使用管理界面优雅的关闭或重启虚拟机

没有安装前虚拟机的IP地址无法获取

生产主要使用CentOS7.6的系统(其它CentOS系列基本相同),安装如下:

1 2	[root@dns01 ~]# yum install centos-release-ovirt42 [root@dns01 ~]# yum install -y ovirt-guest-agent-common
