      *Cause*: Installing a cluster on GCP in us-south1 or us-central1 (the two that currently have AI zones) without specifying 'zones' in your install-config.
      *Consequence*: The installer will select the AI zone as one of the zones it defaults to. That zone is unlikely to have the machine types the installer wants to see for control plane and compute nodes, and installation will fail.
      *Fix*: AI zones are excluded from installer default-zone selection.
      *Result*: Bug doesn’t present anymore.

      This is a clone of issue OCPBUGS-74625. The following is the description of the original issue:
      —

      Description of problem

      GCP has added two AI zones, so all GCP installs to us-south1 and us-central1 regions may fail unless you explicitly select zones in your install-config. All existing OCP installers are exposed, with from 4.12 through 4.22. The only known mitigations are explicitly setting zones in the install-config, or using a region that does not include AI zones.

      Version-Release number of selected component

      All installer versions, at least as far back as 4.12, and probably all v4 GCP installers ever.

      How reproducible

      Every time? At least very common.

      Steps to Reproduce

      1. Create a GCP clustr in either us-south1 or us-central1, and do not specify zones in the install-config.

      Actual results

      Watch the install fail with messages like minimum worker replica count ... not yet met and ...-ai... zone references in the installer logs.

      Expected results

      Successful installs.

      Workaround

      Specify the desired list of zones in which you want to install.
