Stay tuned! Add VM network VLANs. This is preventing VCSA backups from being made now because it complains that not all required services are running so something is still messed up. This is used to manage the intra-cluster certificates (protecting communications between ESXi hosts, and between ESXi hosts and vCenter Server), as well as what is called the Machine Certificate. The Machine Certificate, despite its name, is what us humans see in our browsers when we log into the vSphere Client. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. The kubeconfig file contains information about the cluster that is used by the CLI to connect a client to the correct cluster and API server.

You must remove the bootstrap machine from the load balancer at this point. Image registry storage configuration", Collapse section "1.1.17.2. To complete a restricted network installation, you must create a registry that mirrors the contents of the OpenShift Container Platform registry and contains the installation media. You can log in to your cluster as a default system user by exporting the cluster kubeconfig file. An installation where the registry is configured on block storage is not highly available because the registry cannot have more than one replica.
