This is happening "sometimes", in the baremetal CI.

When the cluster is being installed and all the two masters and three workers become ready, we expect the rendezVous host to eventually reboot, install and join the cluster as the third master to conclude the installation.

However, it seems that one of the two masters is not detected as ready, even if `oc get nodes` would show two masters as joined and ready.

This lead the rendezVous host to keep stuck and never reboot to finish the installation by joining the cluster.

    Sometimes. Most of the times it works fine, sometimes it fails, always the same way.

    1. Install an agent-based cluster. The configuration i've faced this with is
      - dhcp
      - ipv4 only 
      - BMO enabled (platform: baremetal)
      - 3 masters + 3 workers

    The installation fails

    The rendezvous host reboots, join the cluster and the installation succeeds.

By using `oc get nodes` and `oc get co`, everything looked good, except the degraded operators due to the missing third master.

example job (from a PR, but no changes are made to the automation for the agent installation) https://prow.ci.openshift.org/view/gs/test-platform-results/pr-logs/pull/openshift_release/54483/rehearse-54483-periodic-ci-openshift-hypershift-release-4.16-periodics-mce-e2e-agent-connected-ovn-ipv4-metal3-conformance/1817908001202245632

Also, in the journal, right after the timeout of the cluster installation:
