CentOS7 KVM 虚拟机 libvirtd 操作体验

物理机操作系统：
CentOS-7-x86_64-DVD-1708.iso
Mini安装， 无其他选项

[root@localhost ~]# grep -Ei 'vmx|svm' /proc/cpuinfo  #确定 开启的 虚拟化指令

配置一个桥接网卡：

物理机只有共有1个网卡， 我使用路由器的DHCP为OS分配IP

创建桥接网卡配置文件：

强烈建议使用系统配置文件， 配置桥接网卡!

网上一搜 KVM桥接， OpenVPN桥接， 全是使用brctl这工具，实测可用性不稳定。
brctl 这个工具， 临时设置一下， 凑合着用还可以， 想要达到工业级的稳定， 就不好说了。
brctl 设置的桥接， 每隔5天左右， 会莫名其妙的失灵，然后导致系统网络故障。
