Hi Dan, Thanks a lot for your response. Even after properly updating the undercloud.conf file and checking the network configuration, undercloud deployment still fails. To recreate the issue , I am mentioning all the configuration steps: 1. Installed CentOS Linux release 7.2.1511 (Core) image on baremetal. 2. created stack user and provided required permission to stack user . 3. setting hostname sudo hostnamectl set-hostname rdo-undercloud.mydomain sudo hostnamectl set-hostname --transient rdo-undercloud.mydomain [stack@rdo-undercloud etc]$ cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.0.2.1 rdo-undercloud undercloud-rdo.mydomain 4. enable required repositories sudo yum -y install epel-release sudo curl -o /etc/yum.repos.d/delorean-liberty.repo https://trunk.rdoproject.org/centos7-liberty/current/delorean.repo sudo curl -o /etc/yum.repos.d/delorean-deps-liberty.repo http://trunk.rdoproject.org/centos7-liberty/delorean-deps.repo 5. install repos sudo yum -y install yum-plugin-priorities sudo yum install -y python-tripleoclient 6. update undercloud.conf [stack@rdo-undercloud ~]$ cat undercloud.conf [DEFAULT] local_ip = 192.0.2.1/24 undercloud_public_vip = 192.0.2.2 undercloud_admin_vip = 192.0.2.3 local_interface = enp6s0 masquerade_network = 192.0.2.0/24 dhcp_start = 192.0.2.150 dhcp_end = 192.0.2.199 network_cidr = 192.0.2.0/24 network_gateway = 192.0.2.1 discovery_iprange = 192.0.2.200,192.0.2.230 discovery_runbench = false [auth] 7. install undercloud openstack undercloud install install ends in error: Error: /Stage[main]/Neutron::Keystone::Auth/Keystone::Resource::Service_identity[neutron]/Keystone_user[neutron]: Could not evaluate: Execution of '/bin/openstack domain show --format shell Default' returned 1: Could not find resource Default Error: /Stage[main]/Heat::Keystone::Auth/Keystone::Resource::Service_identity[heat]/Keystone_user[heat]: Could not evaluate: Execution of '/bin/openstack domain show --format shell Default' returned 1: Could not find resource Default Error: Could not prefetch keystone_service provider 'openstack': Execution of '/bin/openstack service list --quiet --format csv --long' returned 1: Gateway Timeout (HTTP 504) Error: Not managing Keystone_service[glance] due to earlier Keystone API failures.

That would get rid of the configuration files, etc. that are in ~stack, and generally make your life harder than it needs to be. Anyway, it isn't necessary. You can do a procedure very much like what you do when upgrading the undercloud, with a couple of extra steps. As the stack user, edit your undercloud.conf, and make sure there are no more typos. If the typos were in the network configuration, you should delete the bridge and remove the ifcfg files: $ sudo ifdown br-ctlplane $ sudo ovs-vsctl del-br br-ctlplane $ sudo rm /etc/sysconfig/network-scripts/*br-ctlplane Next, run the underclound installation again: $ sudo yum update -y # Reboot after if kernel or core packages updated $ openstack undercloud install Then proceed with the rest of the instructions. You may find that if you already uploaded disk images or imported nodes that they will still be in the database. That's OK, or you can delete and reimport. -- Dan Sneddon | Principal OpenStack Engineer dsneddon(a)redhat.com | redhat.com/openstack 650.254.4025 | dsneddon:irc @dxs:twitter ________________________________ Learn more on how to switch to Sprint and save 50% on most Verizon, AT&T or T-Mobile rates.
