SUMMARY

Support for Kubernetes Versions 1.25.0 and 1.26.0 is not working. The latest version of kubernetes that can be started with the officially published ISOs is 1.24.0. Despite the wording on the [documentation](NOTE: From ACS 4.16 onwards, Kubernetes versions >= 1.20.x are only supported (https://endoflife.date/kubernetes).): "From ACS 4.16 onwards, Kubernetes versions >= 1.20.x are only supported (https://endoflife.date/kubernetes)."

STEPS TO REPRODUCE

1. Add the kubernetes ISO for version >1.24.0 from http://download.cloudstack.org/cks/ to cloudstack as a new kubernetes version under Images/Kubernetes ISOs
2. Create a kubernetes cluster using the UI

EXPECTED RESULTS

The kubernetes cluster is created.

ACTUAL RESULTS

The form on the UI stays on screen and shows the loading status. For more than an hour. Reloading the page stops the creation process.
