instack network settings

Description of problem:
The dns_nameservers for the provisioning network on the undercloud is set to 192.168.122.1 within a baremetal environment which breaks name resolution on overcloud nodes. 

Version-Release number of selected component (if applicable):
[stack@bldr16cc09 ~]$ rpm -qa | grep tripleo
openstack-tripleo-common-0.0.0.post4-1.el7ost.noarch
openstack-tripleo-heat-templates-0.8.4-2.el7ost.noarch
openstack-tripleo-image-elements-0.9.3-1.el7ost.noarch
openstack-tripleo-0.0.5-999.el7ost.noarch
openstack-tripleo-puppet-elements-0.0.1.dev55-1.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. install undercloud
2. neutron net-list
3. neutron subnet-show <subnet_id>

Actual results:
dns_nameservers set to 192.168.122.1

Expected results:
We should be able to provide DNS servers in the instack.answers file so overcloud nodes get a valid DNS server via DHCP on the provisioning network.

Additional info:
I'm attaching my instack.answers file and out of network related settings.

Comment 6 Marius Cornea 2015-06-29 09:07:11 UTC
Where should we set the dns server(s)? I don't see anything related in undercloud.conf but I might be missing something. Thanks

Comment 7 Giulio Fidente 2015-06-30 13:50:37 UTC
Marius, can you confirm your overcloud dns is not pointing to 192.168.122.1 anymore though? (but to the neutron managed dnsmasq running in the undercloud)

Comment 8 Marius Cornea 2015-06-30 14:46:51 UTC
Confirmed, overcloud resolv.conf contains the ip address set on the dhcp namespace on the undercloud.

you set the dns servers by running a neutron subnet-update command prior to deploying the overcloud. this is included in the documentation.
