Prepare a Harvester cluster with enough cpu, memory and disks for K3s guest cluster
Create a Rancher instance
Import Harvester in Rancher and create cloud credential
ssh to Harvester management node
Extract the kubeconfig of Harvester with cat /etc/rancher/rke2/rke2.yaml
Change the server value from https://127.0.0.1:6443/ to your VIP
Copy the kubeconfig and add into your local ~/.kube/config file

Use the new generate_cloud_provider_config.sh to generate cloud-config content for csi-driver

./generate_cloud_provider_config.sh <serviceaccount name> <namespace>

e.g ./generate_cloud_provider_config.sh k3s default

mkdir -p /var/lib/rancher/rke2/etc/config-files

Add the cloud-provider-config file from the cloud-config part of output generated from script
```
vim /var/lib/rancher/rke2/etc/config-files/cloud-provider-config
```
Access k3s guest cluster on Rancher
Switch to All Namespace
Open Apps -> Charts
