[Prepare the Environment for an NKP Deployment] When deploying NKP using the Nutanix provisioning method (CAPX), what are the supported OS platforms?

According to the official Nutanix Karbon Platform (NKP) documentation, when deploying Kubernetes clusters using the Nutanix provisioning method (CAPX), the supported guest operating systems for worker nodes are specific versions of Rocky Linux and Ubuntu. The documentation explicitly lists Rocky Linux 8.7 and Ubuntu 22.04 as the validated and supported platforms. This ensures that the underlying nodes are fully compatible with the Cluster API Provider for Nutanix (CAPX) for automated lifecycle management, scaling, and operations within the Nutanix Cloud Platform.

A: CentOS is not an officially supported guest OS for NKP worker nodes; support has transitioned to Rocky Linux.

C: Flatcar is not listed as a supported guest OS for worker nodes in the official NKP documentation.

D: CentOS is not a supported OS for NKP worker nodes, making this option incorrect as it is no longer the standard.
