Have you tried running with the nodes on the 2.6 kernel branch?

I though I read someplace that there was a change made to the 3.10 
kernel that was causing a few people issues....although we are using 
mixed kernels without issue.

Other than that...have you used omping to test multicast between nodes?

https://pve.proxmox.com/wiki/Multicast_notes

We used this in our testing and it will help determine if multicast 
packets are being sent and received between each of your servers.
