In practice, the actual possible node count may be limited by the host and network performance. Additionally, it is important to consider any security requirements and to properly configure the firewall to meet these requirements. Proxmox VE utilizes SSH tunnels for various features. Proxmox Cluster is a group of physical servers that work together to provide a virtual environment for creating and managing virtual machines and other resources. Once the cluster has been configured, you can add virtual machines to the cluster. This is not optimal both because

Right-click a virtual machine, then select Migrate. To join additional nodes to the cluster, you will need to use the following join cluster command on each node: This command will provide the necessary information to join the cluster, including the IP address of the main node and the cluster communication port. This ensures that the node can be added to another cluster again
