设备eth0似乎不存在，从而延迟了初始化

我已经克隆了一个软呢帽，现在尝试配置网络接口。每次添加新的NIC时，它都以编号eth3（而不是eth0）开头。我曾尝试删除和修改70-persistent-net.rules以及，network-scripts/eth0但似乎没有任何方法可以解决此问题。这是我机器的一些输出

关于如何解决的任何建议？

空/etc/udev/rules.d/70-persistent-net.rules：

[root@xxxsat601 ~]# echo > /etc/udev/rules.d/70-persistent-net.rules
[root@xxxsat601 ~]#

然后重启。它应该为您重新填充文件。该文件存在，因此，如果您将新的NIC插入到计算机中，看起来好像eth0它不会采用您eth0的IP配置（如果您从配置中省略了mac地址），而是由新名称调用。

如果截断文件，则所有信息都无法存储在其中，除非这确实是硬件配置。

当您启动到克隆的计算机时，ifconfig -a您将看到没有eth0，但是应该有一个eth1。由于文件原因，它正在尝试启动eth0/etc/sysconfig/network-scripts/ifcfg-eth0。

要解决此问题，请编辑 /etc/udev/rules.d/70-persistent-net.rules。删除eth0的第一个块。将第二个块更改为NAME="eth0"

复制MAC并将MAC替换为 /etc/sysconfig/network-scripts/ifcfg-eth0并在必要时编辑IP。

重新启动VM，您应该一切顺利。这对我有用。
