Cobbler commands fail in the build node in Full HA mode

[Shweta P]

The puppet apply run on the build node completed with some cobbler issues.

puppet apply -v /etc/puppet/manifests/site.pp | tee puppet.log

Cobbler commands would not work, it would return this error

cobbler

httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback:

Repeated puppet runs did not help.

I changed this variable to true and i was able to get apache and cobbler working on my build node

In the later stage of the deployment, when I ran the puppet agent on the control node, it complained with a horizon error.

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Apache::Vhost[horizon_vhost]: Mixing IP and non-IP Listen directives is not possible; check the add_listen parameter of the apache::vhost define to disable this at /usr/share/puppet/modules/apache/manifests/vhost.pp:344 on node control01.ctocllab.cisco.comWarning: Not using cache on failed catalogError: Could not retrieve catalog; skipping run

I reset the apache variable back to false(that I had set to true earlier), to allow the puppet run to proceed succesfully.

So I need to toggle the value of apache::default_vhost at different points of time during the install.
