There is an option to remove the set runtime class of the reservation pods: https://github.com/NVIDIA/KAI-Scheduler/blob/main/deployments/kai-scheduler/templates/kai-config.yaml#L62

Also you can try with kind - our e2e tests use kind.

This assumes that the nvidia runtime class exists in the cluster, if it doesn't you should also follow this: https://github.com/NVIDIA/KAI-Scheduler?tab=readme-ov-file#openshift
