[PVE-User] Cluster creation using specific IP or interface

My networks are already in different vlans. My issue is that the synchronization of ram, while migrating VMs, seems to be happening over the 10.135 network. For me this means that if you migrate a vm between machines that are in different racks... The traffic ends up traversing 3 switches before reaching its destination. This totally defeats the purpose of the totally redundant 10gig network I have in place.
So if I understand correctly 'pvecm create' uses '/etc/hostname' and then uses /etc/hosts to resolve its IP?
