IPv6-only installation with interface bonding in private VLAN fails host validation.  
    

4.14.22
    

Customer can, I do not have the hardware to be able to try a reproducer.

    1. Sep up private VLAN.
    2. Prepare agent-config-yaml with interface bonding for nodes
    3. Attempt to install 4.14.
    

    Hosts will fail validation and install will not complete.

    Hosts to pass validation and install will continue to succeed.

    Currently the hosts never become ready and I see near the end of the journal export a 
lot of interface devices flipping back and forth between failed and connected. The 
install log looks like validation is failing because all nodes cannot reach the rest of the 
hosts:
WARNING Host worker-0.ocp-cluster.ccpcfx.com validation: No connectivity to the majority of hosts in the cluster
However, ping6 tests between hosts are successful.

Messages in the journal.export seems to indicate Network Manager is trying to activate the other NICs despite the config calling them out as absent:
