Description of problem:
I discovered a pxe-less host (with and w/o dhcp). Host was discovered successfully. However when I click on provision to provision the host with rhel67 os, I didn't see the kexec on the installer. 

On host console, discovery status was appearing and after a few minutes host rebooted and a login screen appears. On login, I can all anaconda-cfg.ks file and install.log file. 

So missing thing is user won't be able to see installer progress from console. User would get Discovery status screen to login prompt.

However if I provision the discovered host with rhel7 then I can see anaconda installer and install progress on console like package installation and post install steps.

Version-Release number of selected component (if applicable):

Sat 6.1.5 compose3(Satellite-6.1.0-RHEL-7-20151204.0)
rubygem-hammer_cli_foreman_discovery-0.0.1.10-1.el6_6sat.noarch
rubygem-smart_proxy_discovery-1.0.3-2.el6.noarch
ruby193-rubygem-foreman_discovery-2.0.0.22-1.el6_6sat.noarch
foreman-discovery-image-3.0.5-3.el7sat.noarch


How reproducible:
always

Steps to Reproduce:
1. discovered a pxe-less host
2. provision it with rhel67
3.

Actual results:
User won't be able to see installer progress like package install or post-install on console. Directly login screen appears after Discovery Status screen. It creates a weird situation, like If I see at console whether provisioning started, I won't get any clue because I see the status screen. However If I wait for some-time, direct login screen appears.

It means provisioning works but without showing anaconda installer progress.

Expected results:
Installer progress should be visible on host console while provisioning a pxe-less discovered host with rhel67
