Re: NIC not found after removing for rhel 6 vm

+1 nielse and +1 gortee

edit /etc/udev/rules.d/70-persistent-net.rules

comment out all previous versions of eth0 (keep the one with the new MAC - you can check the MAC in vSphere VM settings)

Then you have the choice of editing the /etc/sysconfig/network-scripts/ifcfg-eth0 file directly if you know what you're doing (make sure ONBOOT=YES )

At minimum it should look like this:

DEVICE=eth0 

BOOTPROTO=none 

ONBOOT=yes 

NETWORK=10.0.1.0 

NETMASK=255.255.255.0 

IPADDR=10.0.1.27 

USERCTL=no

or by running 'system-config-network' and use the GUI

Make sure the NIC is set to connect at startup in VM settings...

Once configured, reboot the VM

There you should have your new NIC shown in ifconfig.
