我在运行 Ubuntu 12.04 的 VMware 上启动 eth1 和 eth0 时遇到了问题，我有 2 个网桥和 1 个 NAT，这是我的 ifconfig

这是我的界面

auto eth1

这是我在运行 /etc/init.d/networking restart 时遇到的错误

Failed to bring up eth1.
我尝试运行 ifup -v 来显示有关 eth0 和 eth1 的更多信息，它给出了这个。
root@ubuntu:/home/advitor# ifup -v eth1
Configuring interface eth1=eth1 (inet)
run-parts --verbose /etc/network/if-pre-up.d

我希望您能指导我如何解决这个问题。

显然，不再建议使用 /etc/init.d/networking restart（如您的输出所示）。如解释的那样这里，首选方法是手动关闭和打开接口。
您可以尝试一下并看看是否有帮助吗？
ifdown eth0
ifup eth0
ifdown eth1
ifup eth1
