The installer doesn’t do precheck if node architecture and vm type are consistent for aws and gcp, it works on azure    

    4.15.0-0.nightly-multi-2023-12-06-195439 

   Always 

    1.Config compute architecture field to arm64 but vm type choose amd64 instance type in install-config     
    2.Create cluster 
    3.Check installation     

Azure will precheck if architecture is consistent with instance type when creating manifests, like:
12-07 11:18:24.452 [INFO] Generating manifests files.....12-07 11:18:24.452 level=info msg=Credentials loaded from file "/home/jenkins/ws/workspace/ocp-common/Flexy-install/flexy/workdir/azurecreds20231207-285-jd7gpj"
12-07 11:18:56.474 level=error msg=failed to fetch Master Machines: failed to load asset "Install Config": failed to create install config: controlPlane.platform.azure.type: Invalid value: "Standard_D4ps_v5": instance type architecture 'Arm64' does not match install config architecture amd64

But aws and gcp don’t have precheck, it will fail during installation, but many resources have been created. The case more likely to happen in multiarch cluster    

The installer can do a precheck for architecture and vm type , especially for heterogeneous supported platforms(aws,gcp,azure)
