Are you using a managed switch?  We had similar results [ see proxmox 
2.0 wiki , user name bread-baker ] when using Netgear managed switches.

After switching to non managed switches [ which should  be used in a 
cluster according to what I've read an experienced  - google ' sheepdog 
switches ' , we were able to create clusters and add nodes.
