# 背景
|
|
|
|
|
|
|
|
|
|
因为最近在折腾一些linux相关的软件,所以需要频繁创建Centos虚拟机,故使用了PVE的模板功能,配置好必须的软件,作为一个模板,这样虚拟机创建更快。
|
|
|
|
|
|
|
|
|
|
缺点:
|
|
|
|
|
|
|
|
|
|
- hostname一样,每个虚拟机需要改一下
|
|
|
|
|
- 网络因为使用的静态IP,复制完成后,需要改一下IP
|
|
|
|
|
|
|
|
|
|
修改完IP后,发现网络无法启动了

核心报错:
|
|
|
|
|
|
|
|
|
|
```sql
|
|
|
|
|
connection activation failed no suitable device found for this connection
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
连接激活失败,未找到适合此连接的设备。
|
|
|
|
|
|
|
|
|
|
也就是说网卡找不到。

发现网卡物理地址有配置,而且复制虚拟机基于虚拟磁盘复制,此文件肯定不会变。故这个网卡地址是一样的。PVE复制的时候又会生成新的网卡地址。

# 修复
|
|
|
|
|
|
|
|
|
|
变更网卡地址即可,寻找PVE生成的网卡地址

然后更新到centos配置文件中,重启网络,即可解决。
