      * Previously, the Bare Metal Operator (BMO) container had a `hostPort` specified as `60000`, but the `hostPort` was not actually in use despite the specification. As a result, other services could not use port 60000. This fix removes the `hostPort` specification from the container configuration. Now, port 60000 is available for use by other services.

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

      4.14.0-rc.0

      How reproducible:

      so far once

      Steps to Reproduce:

      1. Deploy disconnected baremetal SNO node with dualstack networking with agent-based installer
2.
3.

      Actual results:

      metal3-baremetal-operator pod fails to start

      Expected results:

      metal3-baremetal-operator pod is running

      Additional info:

      Checking the pots on node showed it was `kube-apiserver` process bound to the port:

tcp   ESTAB      0      0                                                [::1]:60000                        [::1]:2379    users:(("kube-apiserver",pid=43687,fd=455))


After rebooting the node all pods started as expected
