      • QE infrastructure supports deploying heterogeneous multi-arch clusters (AMD64 + ARM64 workers)
      • CI pipelines can execute tests on multi-arch clusters
      • Golden images for both AMD64 and ARM64 architectures are available and validated
      • DataSources correctly pull images for all supported architectures in the cluster
      • VMs can be scheduled on the correct architecture worker nodes

      Goal

      We should support deployment and upgrade of multi-arch clusters with heterogeneous workers.
      It requires:

      • heterogeneous golden images support
      • instance type to let the VM owner require an arch for the VM
        ....

      User Stories

      • As a VM owner, I want to run a VM running ARM RHEL on an ARM worker, regardless of the architecture that run my cluster's control plane.
        • currently, when pointing to a ContainerDisk image URI, I cannot specify which architecture is being imported.
      • As a cluster admin, I want my DataSources to pull up-to-date images of all architectures supported in my cluster.

      Non-Requirements

      • List of things not included in this epic, to alleviate any doubt raised during the grooming process.
