      Starting with 4.14, MachineAPI is marked as an optional capability. For common IPI clusters (not SNO and not compact), the installation will fail if the "MachineAPI" capability is disabled in install-config.yaml. The bug fix adds a pre-check in openshift-install to display an error message indicating that MachineAPI is disabled and should be enabled for common IPI clusters.

      Description of problem:

      On 4.14, 'MachineAPI' is marked as optional capability which will disable two operators machine-api and cluster-autoscaler.

epic link: https://issues.redhat.com/browse/CNF-6318

And operator machine-api is required for common IPI (no SNO and no compact) cluster, so if disabling "MachineAPI" in install-config.yaml, common IPI cluster will be installed failed.

Suggest to have pre-check on installer side for common IPI (no SNO and no compact) when running "openshift-installer create cluster". If MachineAPI is disabled, installer should exit with corresponding messages.

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

      4.14.0-0.nightly-2023-06-30-131338

      How reproducible:

      Always

      Steps to Reproduce:

      1. Prepare install-config.yaml and set baselineCapabilitySet as None, make sure that compute node number is greater than 0.
2. Run command "openshift-install create cluster" to install common IPI
3.

      Actual results:

      Installation failed since missing machine-api operator

      Expected results:

      Installer should have pre-check for this scenario and exit with error message if MachineAPI is disabled
