From the documentation, it seems to suggest that using a separate network interface for the cluster is optional, but when I try to create a cluster, there are no available interfaces to use. The current deployment only has one interface which is slaved by the linux bridge. I can add another NIC in the future, but I would prefer to test the feature without having to add a bunch of NICs to each node. Is there anyway to use the existing interface to test this feature?
