      This is a clone of issue OCPBUGS-1557. The following is the description of the original issue:

      Seen in an instance created recently by a 4.12.0-ec.2 GCP provider:

        "scheduling": {
          "automaticRestart": false,
          "onHostMaintenance": "MIGRATE",
          "preemptible": false,
          "provisioningModel": "STANDARD"

      From GCP's docs, they may stop instances on hardware failures and other causes, and we'd need automaticRestart: true to auto-recover from that. Also from GCP docs, the default for automaticRestart is true. And on the Go provider side, we doc:

      If omitted, the platform chooses a default, which is subject to change over time, currently that default is "Always".

      But the implementing code does not actually float the setting. Seems like a regression here, which is part of 4.10:

      $ git clone https://github.com/openshift/machine-api-provider-gcp.git
      $ cd machine-api-provider-gcp
      $ git log --oneline origin/release-4.10 | grep 'migrate to openshift/api'
      44f0f958 migrate to openshift/api

      But that's not where the 4.9 and earlier code is located:

      $ git branch -a | grep origin/release

      Hunting for 4.9 code:

      $ oc adm release info --commits quay.io/openshift-release-dev/ocp-release:4.9.48-x86_64 | grep gcp
        gcp-machine-controllers                        https://github.com/openshift/cluster-api-provider-gcp                       c955c03b2d05e3b8eb0d39d5b4927128e6d1c6c6
        gcp-pd-csi-driver                              https://github.com/openshift/gcp-pd-csi-driver                              48d49f7f9ef96a7a42a789e3304ead53f266f475
        gcp-pd-csi-driver-operator                     https://github.com/openshift/gcp-pd-csi-driver-operator                     d8a891de5ae9cf552d7d012ebe61c2abd395386e

      So looking there:

      $ git clone https://github.com/openshift/cluster-api-provider-gcp.git
      $ cd cluster-api-provider-gcp
      $ git log --oneline | grep 'migrate to openshift/api'
      ...no hits...
      $ git grep -i automaticRestart origin/release-4.9  | grep -v '"description"\|compute-gen.go'
      origin/release-4.9:vendor/google.golang.org/api/compute/v1/compute-api.json:        "automaticRestart": {

      Not actually clear to me how that code is structured. So 4.10 and later GCP machine-API providers are impacted, and I'm unclear on 4.9 and earlier.
