1. Shut down the virtual machine.
2. Find the location of .vmx file of your installed Guest OS
3. Open the virtual machine’s configuration file (.vmx) in a text editor.
4. Add or edit lines as below,
ethernet0.virtualDev = “e1000”

DEVICE=ens1
BOOTPROTO=dhcp
TYPE=Ethernet
ONBOOT=yes
IPV6INIT=no
NM_CONTROLLED=no
USERCTL=no
PEERDNS=yes
PEERROUTES=yes

Restart Network Service on Linux

Once the network file is created, use ifup network commands to bring up the ethernet device.

[selva@rhel7-host ~]# sudo ifup ens1

if the above command not found, restart the entire network service using systemctl command on RHEL or any other related commands available on your Linux Server.

[selva@rhel7-host ~]#  sudo /etc/init.d/networking restart
