moved metal to VM - how do I reset NIC entirely

I have a PBX (phone system) that has been running on an old Dell computer. the interface was enp0s25 or something like that rather than eth0.
As a PBX, the machine is running as few things as possible; it is a Centos 7 based install and doesn't have a GUI.
I've used Clonezilla to bring the machine across into a VM.

I've tried deleting /etc/udev/rules.d/70* and files in /var/lib/dhclient.

I can get the 'new' NIC up with sudo dhclient -v, but that's post boot.

What's the best way to tell the VM to 'forget' the NIC settings it had and use the new eth0 as default?

Thanks for your reply.

I found the file which had the old reference and changed the reference from enp0s25 to eth0. This seems to have worked.

But now I have an ifcfg-enp0s25 with eth0 references.

Is there a cleaner way to fix this? (It does seem to be working, so 'yay'!)
