We installed Cent O.S on to the bare metal. then we tried with the same steps but we did not get the same cinder.conf in the /etc/cinder/ and we tried to install the openstack

# yum install -y http://rdo.fedorapeople.org/openstack/openstack-grizzly/rdo-release-grizzly-2.noarch.rpm

# yum install -y openstack-packstack

# packstack --allinone

after this we got the error

ERROR : Error during puppet run : err: /Stage[main]/Packstack::Netns/Exec[netns_dependecy_install]/returns: change from notrun to 0 failed: yum update -y kernel iputils iproute returned 1 instead of one of [0] at /var/tmp/packstack/a83e49ab06234141ad9efa5937fe4135/modules/packstack/manifests/netns.pp:13
