If you are going to add harvester as virtualization management in the rancher you installed on the vms inside harvester cluster looks like a loop and its not good approach in my opinion. In case of harvester upgrade problem you are left without management or anything. I would suggest u have the rancher mgmt outside the harvester cluster and then u can quickly deploy k3s/rke1-2 clusters however you want from rancher-mgnt to harvester cluster This is how im doing it and im running rancher using openSuse microOS with Rke2 in a hp-thinclient
