I made the following changes to update content for the RDO Icehouse release packages: 1) Changed RDO repository package from rdo-release-icehouse-2.noarch.rpm to rdo-release-icehouse-3.noarch.rpm. 2) Added "python-glanceclient" to list of packages to install for glance. 3) Added "auth_protocol = http" and "auth_port = 35357" to glance-api.conf and glance-registry.conf. 4) Changed "rpc_backend = nova.openstack.common.rpc.impl_qpid" to "rpc_backend = qpid" in nova.conf on all nodes. 5) Removed "python-novaclient" from list of packages to install for neutron on the network node. 6) Added "python-neutronclient" to list of packages to install for neutron controller node.
