如果报错就安装一下

apt install openvswitch-switch -y
systemctl start ovsdb-server
systemctl enable ovsdb-server

修改配置文件，可能不是这个文件名，但是大概在/etc/netplan的文件夹下

vim /etc/netplan/50-cloud-init.yaml

network:
    ethernets:
        ens160:
            dhcp4: true
    version: 2

改成下面的格式

network:
    ethernets:
      ens160:
          dhcp4: false
          addresses:
              - 10.16.6.100/16
          routes:
              - to: 10.16.0.0/16
                via: 10.16.255.254
                metric: 100
      ens192:
          dhcp4: false
          addresses:
              - 10.16.6.101/16
          routes:
              - to: 10.16.0.0/16
                via: 10.16.255.254
                metric: 200
      ens36:
            dhcp4: true
    version: 2                    

生效

netplan apply

绑定驱动

如果 dev 在运行

sudo ip link set dev 接口名 down

sudo ip link set dev 接口名 up
