Installing a BM-IPI cluster fails due ovs-configuration.service inability to create the br-ex interface as NM create the connections with the duplicate "Wired Connection" and same UUID:   

cat nmcli_con_show_id_Wired_Connection | grep "connection.id\|connection.uuid\|connection.interface-name\|connection.autoconnect-priority"
connection.id:                          Wired Connection
connection.uuid:                        6d615afb-b7a6-42d0-af47-31c4e2c6ebf2
connection.interface-name:              --
connection.autoconnect-priority:        -100
connection.id:                          Wired Connection
connection.uuid:                        5b13ef24-be53-46a2-9585-e1fa1c6c141c
connection.interface-name:              --
connection.autoconnect-priority:        -100

With the duplicated name it shows the two connections at once and none of the two has an interface apparently assigned, both have the same priority which could potentially clash at the time of bringing up the interface or better at the time that ovs-configure script runs.

Interestingly while showing them via `nmcli con show` one of the two shows the associated interface:

cat nmcli_con
NAME              UUID                                  TYPE      DEVICE
Wired Connection  6d615afb-b7a6-42d0-af47-31c4e2c6ebf2  ethernet  ens1f0
lo                2c8e4f4f-e3bb-4671-b906-3b117c6b1d0c  loopback  lo
Wired Connection  5b13ef24-be53-46a2-9585-e1fa1c6c141c  ethernet  --

    Tested in OCP 4.14.17

   NOT ALWAYS REPRODUCIBLE (on client env)

   1. Start default installation of OCP IPI BM cluster using DHCP.
   2. Wait for the node for the first automated reboot.
   3. Check the NM connection created.     
   4. Wait for the installation to fail

    Failed installation 

     A succesfull installation without any workaround
