Aha. I think an underlying assumption of the Proxmox VE environment is  
that if you have multiple nodes in a cluster, they all have exactly  
the same NIC resources available to them. This is so that you can  
smoothly (either online or offline) migrate a VE from one node to  
another, and whatever interfaces its IP addresses were bridged to on  
one will be able to be mapped to the same bridge places on the new  
node to which it's moved. If you make one node with that third NIC,  
but then another node does not have the third NIC, then you have a VE  
that's effectively "stuck" to one node and unable to be migrated. In  
that case, I believe Dieter would say you are violating the spirit of  
the Proxmox clustering (not to put words in your mouth, Dieter).

I believe that's the crux of what you (Victor) are seeing as a user  
interface bug or limitation.
