最近在VMware workstation 8上安装了RHEL 7.0 x64，但是显示没有网卡，ifconfig只显示lo设备
[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 0
到/etc/sysconfig/network-scritps里发现只有lo这个设备
但是明明是有这块网卡的
[root@openstack ~]# lspci |grep -i eth
02:01.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
google了下，试了下面几种方式，都不行
1，开机删掉网卡
2，重启
3，开机后加网卡
4，重启，ifconfig还是只有lo
-------------------------------
1，开机删掉网卡
2，关机下加网卡
3，开机，还是不行
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
https://access.redhat.com/discussions/1120733
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，通过ifconfig能看到网卡
[root@openstack ~]# ifconfig
