The create-node-* commands are remote commands and therefore must
connect to the DAS. The --host parameter is specifying the DAS to
connect to (not the host to create the instance on) so yes the
DAS needs to be running on that host.

--host is the DAS host. When running create-node-config there won't
be any instance host specified. When running create-node-ssh we
must support --nodehost to specify the instance host.
