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-fd63c6c419edovs_version: 2.9.8
4创建OVS 虚拟交换机
ovs-vsctl add-br br0
5查看openvswitch

e436b05b-210c-468a-9d94-fd63c6c419edBridge br0Port br0Interface br0type: internalovs_version: 2.9.86删除OVS 虚拟交换机并查看
ovs-vsctl del-br br0
7再次查看openvswitch。显示已删除
root:/# sudo ovs-vsctl show
e436b05b-210c-468a-9d94-fd63c6c419edovs_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 typeinternal
2将if01端口设置为access VLAN模式
ovs-vsctl set port if01 VLAN_modeaccess
3)查看openvswitch

1.KVM下的br0和virbr0有何区别
1KVM 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hypervisor的虚拟接口
