ubuntu找不到网卡的问题
After cloning a virtual machine running Ubuntu Server 10.04I found that it didn’t have any network available. Restarting networking gave:
sudo /etc/init.d/networking restart
* Reconfiguring network interfaces...
eth0: ERROR while getting interface flags: No such device
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
eth0: ERROR while getting interface flags: No such device
eth0: ERROR while getting interface flags: No such device
Failed to bring up eth0.The problem lies in the fact that ethernet MAC addresses are cached. You need to remove a file to clear the cached value:
sudo rm /etc/udev/rules.d/70-persistent-net.rules
After a restart of your server you should have networking back again.
