Whenever we’re performing the cloning method we have faced the issue due to wrong or duplicate mac address.
To fix this problem login to your ORACLE Linux server using console and type the following commands
Move to this directory
[root@asmqp ~]# cd /etc/udev/rules.d

Copy it somewhere and I just copied it on my root directory
[root@asmqp rules.d]# cp 70-persistent-net.rules /root/

Remove it (70-persistent-net.rules) from /etc/udev/rules.d
[root@asmqp rules.d]# rm -rf 70-persistent-net.rules
We can use one of them I just mention –rf force to remove
[root@asmqp rules.d]# rm 70-persistent-net.rules
