一、实验

1.OVS 交换机 管理

（1）查看网络信息

    link/ether 52:54:00:2f:20:d6 brd ff:ff:ff:ff:ff:ff

（2）安装 openvswitch–switch

sudo apt-get install openvswitch-switch

（3）查看软件ID与软件版本

root:/# sudo ovs-vsctl show
e436b05b-210c-468a-9d94-fd63c6c419ed
    ovs_version: "2.9.8"

（4）创建OVS 虚拟交换机

ovs-vsctl add-br br0

（5）查看openvswitch

root:/# sudo ovs-vsctl show
e436b05b-210c-468a-9d94-fd63c6c419ed
    Bridge "br0"
        Port "br0"
            Interface "br0"
                type: internal
    ovs_version: "2.9.8"

（6）删除OVS 虚拟交换机并查看

ovs-vsctl del-br br0

（7）再次查看op envswitch。显示已删除

root:/# sudo ovs-vsctl show
e436b05b-210c-468a-9d94-fd63c6c419ed
    ovs_version: "2.9.8"

2.OVS端口 管理

（1）向br0 中添加 if01端口，并且绑定 if01接口，设置端口类型 internal 类型

ovs-vsctl add-port br0 if01 -- set interface if01 type=internal

（2）将if01端口设置为access VLAN模式

ovs-vsctl set port if01 VLAN_mode=access

（3)查看op envswitch

root:/# sudo ovs-vsctl show
e436b05b-210c-468a-9d94-fd63c6c419ed
    Bridge "br0"
        Port "if01"
            Interface "if01"
                type: internal
        Port "br0"
            Interface "br0"
                type: internal
    ovs_version: "2.9.8"

（4）查看网络信息

    ovs_version: "2.9.8"

二、问题

1.KVM下的br0和virbr0有何区别

（1）KVM 的三种网络模式

桥接、仅主机、NAT

（2）区别

默认br0是桥接模式；

virbr0为NAT模式,它其实就是hy pervisor的虚拟接口
