CentOS 7 network install on VMWare Workstation network problem

If we install Centos  7 on Vmware workstation 10 , you can see that the network is not detected. Its because that the v7 3.10 kernel no longer supports the Ethernet Controller device. So once we install the Centos 7Os in Vmware workstation there will not be Network inside the Vm.

I found at https://access.redhat.com/discussions/722093 that its a Bug and can be fixed by editing the vmx file of Vmware Workstation.

I added the following line to my .vmx file:

CODE: SELECT ALL

ethernet0.virtualDev = "e1000"
