Hi,

please don't misunderstand me. If you have multiple nodes, then each of them will have its own ``host`` setting (like, host = node1 for node1 and host = node2 for node2). The important thing is that both the neutron.conf and nova.conf to have the same ``host`` setting on one node. So if you have used the ``host = node1`` in neutron.conf of node1, then do the same in the nova.conf on the same host. And if you have ``host = node2`` in neutron.conf on node2, then you should have the same in the nova.conf.

Kind regards,
Laszlo
