Take a look into the following file: /etc/pve/cluster.cfg
This file is synchronized from the master to all hosts.

In case of any problem or reconfiguration issues and if you do not succeed with the pveca commands, you can do the following:

1. Just stop the cluster tunnel and cluster sync service on the web interface on all nodes.
2. Now correct manually fix/adapt cluster.cfg on all nodes 
3. start the services again.

Testing: 
You need just one physical Proxmox VE server. Just install several Proxmox VE as a KVM guests. Very cool, the only limitation is that you do not have KVM inside the KVM but OpenVZ containers works without any issues (and also the Proxmox VE clustering).
