19、配置环回口地址；
network: version: 2 renderer: networkd ethernets: lo: match: name: lo addresses: [ 7.7.7.7/32 ]
20、Windows dhcp配置参考；

21、配置IP通道；
network: version: 2 ethernets: eth0: addresses: - 1.1.1.1/24 - "2001:cafe:face::1/64" gateway4: 1.1.1.254 tunnels: he-ipv6: mode: sit remote: 2.2.2.2 local: 1.1.1.1 addresses: - "2001:dead:beef::2/64" gateway6: "2001:dead:beef::1"
22、配置SR-IOV 子网卡
network: version: 2 ethernets: eno1: mtu: 9000 enp1s16f1: link: eno1 addresses : [ "10.15.98.25/24" ] vf1: match: name: enp1s16f[2-3] link: eno1 addresses : [ "10.15.99.25/24" ]
