我已经克隆了一个 Fedora,现在尝试配置网络接口。每次我添加新的网卡时,它都会以编号 eth3(而不是 eth0)开头。我尝试删除和修改70-persistent-net.rules
以及 ,network-scripts/eth0
但似乎没有任何方法可以解决问题。这是我的机器的一些输出
[root@abc ~]# ls /sys/class/net
eth3 eth4 lo pan0
[root@abc ~]# cat /etc/udev/rules.d/70-persistent-net.rules

关于如何修复它有什么建议吗?
答案1
空的/etc/udev/rules.d/70-persistent-net.rules
:
[root@xxxsat601 ~]# echo > /etc/udev/rules.d/70-persistent-net.rules
[root@xxxsat601 ~]#
并重新启动。它应该为您重新填充该文件。该文件存在的目的是,如果您将新的 NIC 插入计算机,则它eth0
不会采用您的eth0
IP 配置(如果您在配置中省略了 mac 地址),而是通过新名称进行调用。
如果您截断该文件,则所有信息都无法保存在其中,除非硬件配置确实如此。
答案2
当您启动克隆机器时,输入ifconfig -a
您将看到没有 eth0,但应该有 eth1。由于该文件,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 并替换 MAC /etc/sysconfig/network-scripts/ifcfg-eth0
,并根据需要编辑 IP。
重新启动虚拟机,您应该就可以开始了。这对我有用。
