vmware red hat 5.3系统复制后网卡配置
linux虚拟机在vmware workstation 上复制后，网卡使用手工配置后总是从net8上自动获得地址，无法完成自己配置的地址# ifconfig

# cat /etc/sysconfig/network-scripts/ifcfg-eth0

将网卡目录下备份的所有网卡设备名eth0修改
# cd /etc/sysconfig/network-scripts/
# ls

修改后的效果

原理：linux下设备udev采用动态管理和UUID号有关系
网上有人修改
vi /etc/modprobe.conf
也有人修改
rm -f /etc/udev/rules.d/70-persistent-net.rules
也有人先删除网卡，再添加网卡解决问题
但是5.3遇到的情况是
# ls
05-udev-early.rules51-hotplug.rules60-pcmcia.rules 90-alsa.rules95-pam-console.rules
40-multipath.rules 60-net.rules 60-raw.rules 90-dm.rules 98-kexec.rules
50-udev.rules 60-net.rules.bak85-pcscd_ccid.rules90-hal.rules bluetooth.rules
没有70-persistent-net.rules 这个文件，最后想到是备份网卡修改设备名称解决问题。图形化界面可以在网卡管理里，删除copy产生的网卡，重启网络服务即可。
希望对大家有帮助
