Device eth0 does not seem to be present, delaying initialization.

vmware或kvm xen类型的虚拟机,克隆镜像后,新的Centos无法启动网络,提示Device eth0 does not seem to be present, delaying initialization.
已知的两个解决办法:

(1)
mv /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1
vi /etc/sysconfig/network-scripts/ifcfg-eth0
直接改成
DEVICE=eth1
TYPE=Ethernet
ONBOOT=YES
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=YourIP
GATEWAY=YourGateWay
NETMASK=255.255.255.0
service network restart 就起来了，网卡是eth1

(2)
vi /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE=eth0
TYPE=Ethernet
ONBOOT=YES
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=YourIP
GATEWAY=YourGateWay
NETMASK=255.255.255.0
#DEVICE IPADDR 等都要大写
rm -f /etc/udev/rules.d/70-persistent-net.rules 
reboot
