VlanManager in Multi-Host Mode: Cross-Host Communication

Hi, I am running a 2-compute-node OpenStack Cloud with VMwareESXDriver. Nova-network runs with VlanManager in multi_host mode. The current problem is that an instance on esxi01/compute01 cannot talk to another instance on esxi02/compute02. Both instances are on the same network from an openstack perspective.

It might be my design that cross-host communication like this (VlanManager + multi_host=True) does not work but I wanted to clarify. I would have expected brXZY on the repective nova-compute/nova-network instances would do proxy ARP to make cross-host communication possible.

Should this be working?
