I am trying to do undercloud installation on baremetal for Openstack liberty but the install is failing.

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-... sudo curl -o /etc/yum.repos.d/delorean-deps-liberty.repo http://trunk.rdoproject.org/centos7-l...

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:
