虛擬機拷貝移動之后， ifup eth0出現如下錯誤：
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.
原因
新克隆的虛擬機鏡像的網卡mac地址已經變更。打開虛擬機的.vmx文件，ethernet0.generatedAddress項記錄了該虛擬機的mac地址。
解決辦法：
rm /etc/udev/rules.d/70-persistent-net.rules
通過 vi /etc/network/interfaces 修改ip地址
然后 /etc/init.d/networking restart
