Dear all,
O.S is : Oracle Linux 6.7
I did vmware cloning. (vm1 to vm2)
After cloning, i am getting multiple network adapters are on VM2.
>> Please review attached screenshot - i want to delete ( Auto_eth1, Auto_eth2, and Auto_eth3) permanently ?
I deleted some entries from following file
# cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
