NKP Node OS Image UEFI to Legacy BIOS in NKP Starter

Hello, I have been testing the NKP Starter in my LAB with Nutanix Community and encountered failures in creating the NKP cluster. The deployment of the NKP Cluster uses the NKP Node OS Image in UEFI mode, which, as many know, has an issue if the VM is created with the default network card in the Community Edition CE 2.1 and UEFI Boot. A workaround is to change the network card to the e1000 model, but doing this during the NKP deployment can cause your task to hang. So, in several attempts, I was able to quickly change the network card in time for the cluster creation command to complete the infrastructure deployment operations. NKP Node OS Image (Rocky Linux 9.5-release-1.32.3-20250430150550) for AHV( Version: v2.15.0 ) Is there any way to provide an instruction for the NKP to deploy the infrastructure with Legacy BIOS or to build an NKP Node OS Image without UEFI? It is mentioned in the documentation that the NKP Node OS Image cannot be customized in the NKP Starter version.

NKP installer system whoes

During the installation of the NKP cluster you need to set an IP-address for the CONTROL_PLANE_ENDPOINT. Unfortunately the rocky linux node (nkp-rocky-9.5-release-1.31.4-20250409153435.qcow2) also tries to obtain an IP-adress via DHCP on the same nic. As a result the nic gets 2 IP-addresses in the same subnet (1 from the installer and 1 from the DHCP)  and reports back to nkp with the DHCP address. This results in a failing install of nkp cluster.

expose pod in Kubernetes engine as service.

HiI have a pod with cluster IP already. I want to expose this as load balacner or nodeport service and take one of the private IP from the subnet. However none seem to be working. I just want to know if there is some annotations or additional settings that we need to do to achieve this or exposing pods as service via standard yaml or kubectl commands should work?for example this - kubectl expose deployment sandbox-airflow-web --type=LoadBalancer --name=sandbox-airflow-web-service --namespace=sandbox-airflowdidnt generate any external IP or errors. was stuck in pending. I later patched it to get an IP but there IP didnt return the website.Kubectl patch svc sandbox-airflow-web-service -n sandbox-airflow -p'{"spec": {"type": "LoadBalancer", "externalIPs":["172.20.8.50"]}}'thanks.

Disaster recovery for Nutanix Kubernetes Environment

We have a Nutanix nke environment and would like to activate protected domains so that in the event of a disaster we can move the PD across to our DR site. Currently I have not seen any documentation or a way to configure this. Does anyone know how we can “replicate” our NKE clusters to a DR location in an easy and simple way. My thought is to take the underlying virtual machines and just put them into a PD. However, it does not seem as simple as this. Any guidance would be apricated. We have been receiving conflicting advice from Nutanix technical support. To the point where it does not seem possible and therefore makes NKE not viable to enterprise deployment.

ipvs mode for kube-proxy with MetalLB on NKE

I'm in the process of installing MetalLB on Nutanix Kubernetes Engine (NKE) to provide LoadBalancer services. According to MetalLB's documentation, it prefers (requires) kube-proxy to run in ipvs mode for optimal performance. However, I've noticed that NKE defaults to iptables mode for kube-proxy, and my attempts to switch to ipvs mode have been unsuccessful.Has anyone successfully configured ipvs mode for kube-proxy on NKE? If so, could you share the steps or guidance on how to achieve this? Any tips or resources would be greatly appreciated as the standard documentation and methods don't seem to apply directly to NKE.I referred to this blog: Utilizing MetalLB to Provide LoadBalancer Services for Nutanix Karbon.

What are the Kubernetes versions supported in NKE as of today

I was testing the NKE cluster using Test Drive and noticed that when attempting to create a cluster, the latest version available is 1.19.8. I'm curious if this limitation also applies to the regular NKE clusters, or if NKE supports newer versions beyond 1.19.8. and if so what is the latest version?

Can NKE be installed in a non-nutanix infrastructure?

We are presently engaged with a client who possesses a Nutanix infrastructure and seeks to leverage Nutanix's NKE for deploying their application. Our intention is to utilize their infrastructure as the production setup while concurrently exploring the implementation of an NKE cluster within our VMs, provisioned on a Proxmox server. Despite searching for similar setups, we haven't found relevant precedents. Is it feasible to realize such a configuration?

Nutanix CSI volume driver.RWX support

I need to manage the default ownership/permissions of a mountpoint created by a PVC with ReadWriteMany (RWX) on Red Hat Openshift 4.13, currently not supported by Nutanix CSI volume driver.According to Red Hat, using the current setting of fsGroupPolicy: ReadWriteOnceWithFSType results in the fsGroup only to be respected by the driver if the volume's access mode contains ReadWriteOnce (RWO).According to this link, after changing the fsGroupPolicy parameter to value ‘File’, Kubernetes may use fsGroup to change permissions and ownership of the volume to match user requested fsGroup in the pod's SecurityPolicy regardless of fstype or access mode.https://kubernetes-csi.github.io/docs/support-fsgroup.htmlDoes anyone knows how to approach this?

Beta Kubernetes versions

We noticed that Kubernetes is still in beta version on Prism central. The latest 1.25.6 version is generating an unuseable kubeconfig file which prevents any possible management of the cluster. Also the user rights and roles to create a Kubernetes cluster seem to be mangled which limits the cluster creation to the admin user only. Are there any user who implemented their own Kubernetes cluster by VM's ?
