我在运行Ubuntu12.04的eth1和eth0上遇到问题，我有2桥和1 1NAT，这里是我的ifconfig

Failed to bring up eth1.我试着运行ifup -v来提供更多关于eth0和eth1的信息，它给了我这个信息。
root@ubuntu:/home/advitor# ifup -v eth1
Configuring interface eth1=eth1 (inet)
run-parts --verbose /etc/network/if-pre-up.d
run-parts: executing /etc/network/if-pre-up.d/ethtool

显然，不建议再使用/etc/init.d/networking (正如您的输出所指出的)。正如解释过的这里一样，首选的方法是手动关闭和提升接口。
你能试试这个看看是否有用吗？
