# C7添加ovirt源
[root@localhost ~]# yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm

# 安装ovirt agent tools
[root@localhost ~]# yum install ovirt-guest-agent-common -y

# 启动ovirt-guest-agent，并设置自启

# 参考：https://www.ovirt.org/documentation/vmm-guide/chap-Installing_Linux_Virtual_Machines/
[root@localhost ~]# systemctl start qemu-guest-agent.service
[root@localhost ~]# systemctl enable qemu-guest-agent.service
