Proxmox VE 实现批量增加多网络

前言

实现批量创建多网络，更改主机名称，hosts解析

初始化网卡，主机名称，hosts解析，重启网卡

我的主机六个网卡，使用的有四个网卡，以下一键创建和初始化
主机名称我是以硬件的SN号最为主机的名称，实际环境看主机的需求进行更改
变量host_name_sn获取主机SN号
变量vmbr_IP获取vmbr0 IP地址
变量vmbr_gateway获取vmbr0 网关地址
变量vmbr_bridge桥接的实际网卡接口名称
桥接网卡名称定义必须要以vmbr0.100这样，参考这里，不要自定名称，不支持哦
其它参考官网
Proxmox ve 中文参考文档
