VMware虛擬機克隆Linux系統引起的網卡問題
1. 手動配置靜態網卡地址不生效
2. 網卡名變成了eth1
[root@localhost network-scripts]# ls |grep ifcfg
ifcfg-eth0
ifcfg-lo
[root@localhost network-scripts]# ifconfig
eth1 Link encap:Ethernet HWaddr 00:0C:29:3A:8B:02

[root@localhost network-scripts]# vim ifcfg-eth0
DEVICE=eth0

手動設置靜態ip地址和網關後，保存退出；然後重啟網絡後出現錯誤
[root@localhost network-scripts]# service network restart
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Error: No suitable device found: no device found for connection 'System eth0'.
[FAILED]
[root@localhost network-scripts]#
英漢互譯
No suitable device found: no device found for connection 'System eth0'.
沒有找到合適的設備：沒有找到設備連接的系統eth0”。
總結了以下解決方案
更改ifconfig顯示的eth1網卡名為eth0，並設置static ip地址
編輯/etc/udev/rules.d/70-persistent-net.rules文件，把NAME="eth0"的那行配置注釋掉或者刪掉，把NAME="eth1"的修改成NAME="eth0"，修改後如下：
[root@localhost network-scripts]# vim /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x8086:0x100f (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:52:39:18", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:3a:8b:02", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
查看以下信息
[root@localhost network-scripts]# ls |grep ifcfg-
