VMs with multiple NICs must be mapped in the same sequence from the source as what that guestOS shows to maintain the correct eth#. The MAC addresses will be interchanged

This is the configuration of the VM on RHV:
~~~
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovs-system state UP group default qlen 1000
link/ether 56:6f:c8:78:00:7e brd ff:ff:ff:ff:ff:ff
altname enp0s4
altname ens4
inet6 fe80::546f:c8ff:XXXX:XX/64 scope link
valid_lft forever preferred_lft forever

6: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 56:6f:c8:78:00:28 brd ff:ff:ff:ff:ff:ff
altname enp0s12
altname ens12
inet 172.21.32.XX/26 brd 172.21.32.XX scope global noprefixroute eth4
valid_lft forever preferred_lft forever
inet6 fe80::e8d3:964c:XXXX:XXXX/64 scope link noprefixroute
valid_lft forever preferred_lft forever
~~~

After the migration, we see that the MAC addresses for both eth1 and eth4 have swapped
