Currently Proxmox UI only support single node. I know Cluster support multi modes but has some restrictions:
- We can not have multi servers with same VM/CT ID
- The Cluster config in one node if broken then all nodes has problem then users will over knowledge to use pvecm expected 1, stop xyz, ..... and so on
- Proxmox Cluster not allow multi major version PVE, can not access all Proxmox 3, 4, 5 and 6 in one UI
