    Alwyas

    1. create aws vpc, record all the subnest ID
    2. create a security gourp, record the sg ID
    3. create install-config.yaml, set platform.aws.subnets and platform.aws.defaultMachinePlatform.additionalSecurityGroupIDs together
E.g:
platform:
  aws:
    region: us-east-2
    subnets:
    - subnet-046e3a4618c4e0e4e
    - subnet-0dd99f7e1695a90c8
    - subnet-095f4f02a8b65866c
    - subnet-07e80f7eea3ed3db0
    defaultMachinePlatform:
      additionalSecurityGroupIDs:
      - sg-0594ae9527482c34f

    No panic

    Looks like this is a regression issue introduced by https://issues.redhat.com/browse/CORS-3440
