Red Hat 7.0 安装完后无网卡
最近在VMware workstation 8上安装了RHEL 7.0 x64，可是显示没有网卡，ifconfig只显示lo设备ide
[root@localhost~]# ifconfig
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 0 (Local Loopback)
RX packets 8 bytes 764 (764.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 8 bytes 764 (764.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0oop
到/etc/sysconfig/network-scritps里发现只有lo这个设备google
可是明明是有这块网卡的blog
[root@openstack ~]# lspci |grep -i eth
02:01.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)ci
google了下，试了下面几种方式，都不行文档
1，开机删掉网卡
2，重启
3，开机后加网卡
4，重启，ifconfig仍是只有loget
-------------------------------
1，开机删掉网卡
2，关机下加网卡
3，开机，仍是不行
虚拟机
后来在下面两篇文章中看到原来是虚拟机vmx配置文件中少了一行配置it
https://access.redhat.com/discussions/1120733io
https://communities.vmware.com/thread/477988
1，关机，
2，移除网卡
3，添加网卡
4，往虚拟机vmx配置文件加ethernet0.virtualDev = "e1000"
5，开机，经过ifconfig能看到网卡
