      Environment info:
       * Fully disconnected OCP cluster version 4.14.22
       * NTP-servers configured via machine-config
       ** 10.171.8.5
       ** 10.171.8.4
       * External interface: infra-bond.94 (which comes br-ex after the ovs-configuration.sh is done) 

      Description of problem:

       
       - Chronyd fails to synchonize time during the boot due networking is down at the time when chrony starts, marking both NTP-sources offline and chrony does not recover leaving node time unsynchronized.
       - External networking is not up before the ovs-configuration.service is ready, and only after that NTP-sources can be reached. But chrony has marked sources offline by then, and does not recover.
       - sos-report of one of the nodes:
       -- [https://access.redhat.com/support/cases/#/case/03776816/discussion?attachmentId=a096R00003HlPvjQAF]
       - Must-gather of the cluster is present here:

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

      OCP 4.14.22

      How reproducible:
      Happens after every reboot

      Steps to Reproduce:

      1.Happens after every reboot

      Actual results:
      Initially the network is available, and chronyd-service starts. But soon after (before chronyd finishes the time-sync) the ovs-configure takes the bond-interface down and chrony fails and do not restore on its own once the ovs-configure.sh script is finished.

      Expected results:
      The chronyd should restore on its own once the ovs-configure.sh script is finished without .manual restart should not be required.

      Additional info:

      We have asked the customer to again share the latest sosreports and must-gather report from the time of issue to check more. These are yet to be provided.
