Your Neutron, probably ML2 configuration is incorrect somewhere. You need to double-check it against the installation guide or the NW guide.

Alternatively, you can trace traffic and find out where it disappears.

Since this happens only when VMs are on different hosts, I would guess something is wrong with the mapping of virtual networks to physical interfaces.
