虚拟机linux添加的新网卡重启，没有发现其配置文件eth1的笔记！

1、查看vi /etc/udev/rules.d/70-persistent-net.rules
这里能看到你的网卡信息，找到你对应网卡的NAME
例如（这是我添加新网卡没有显示其配置文件的虚拟机）

# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:52:5c:06", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:52:5c:10", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

2、自己手动创建其配置文件

cd /etc/sysconfig/network-scripts/

cp ifcfg-eth0  ifcfg-eth1

[email protected] network-scripts]# cat ifcfg-eth1

DEVICE=eth1

HWADDR=00:0c:29:52:5c:10

TYPE=Ethernet

UUID=32b82029-c99b-46fd-8afd-091e15a44bbd

NM_CONTROLLED=yes

BOOTPROTO=static

IPADDR=192.168.1.223

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

DNS1=202.106.0.20

3、启动网卡

[[email protected] network-scripts]# ifup eth1

注意，切记不要用[[email protected] ~]# /etc/init.d/network restart。很多人喜欢restart，可是如果自己是远程，服务器出现意外，比如配置失误。可能会带来一些问题。

4、查看配置结果

[[email protected] ~]# ifconfig
