FT2000+ openEuler 20.03 LTS SP3 virsh xml配置qemu kvm虚拟机网络virbr0网桥

参考

https://libvirt.org/formatdomain.html#bridge-to-lan

device节点添加配置

        <interface type='bridge'>
          <source bridge='virbr0'/>
        </interface>

其中virbr0为宿主服务器网桥

完整配置

 启动虚拟机，查看状态

 vnc登录，查看网卡状态

 手动启动eth0

 测试与路由的连通性（即：宿主网桥virbr0）
