Description of problem:
When the VM is started with secondary network interface, the IP address looks like below:
IP addresses
10.131.0.133
192.168.0.1
fe80::ea:87ff:fe00:91

There are 3 IP addresses, but the VM only have two NICs, it's not clear to user that the IPv6 address belongs to which NIC or there are 3 NICs in the VM.

Suggestion:
1. remove the IPv6 address from the 2nd NIC, same as the pod networking, it only has IPv4 address.
2. add the nic name before the address, like
eth0: 10.131.0.133
eth1: 192.168.0.1
fe80::ea:87ff:fe00:91 (if it's kept there)

Version-Release number of selected component (if applicable):
4.15.0

How reproducible:

Steps to Reproduce:

1. configure nncp in networking
2. create nad in networking
3. create a VM with secondary network
4. wait until the VM is running

Actual results:

3 IP addresses present

Expected results:

Make the IP list more readable as suggested.
