Satellite 6.1 on RHEL 6

Really, really reconsider running Satellite 6 on RHEL 6.  While technically Red Hat support it there are just too many performance reasons to ignore RHEL 7.  Get your SOE updated to RHEL 7 if you have to before going with Satellite 6.

Could not set 'present' on ensure: 422 Unprocessable Entity at 12:/usr/share/katello-installer/modules/foreman_proxy/manifests/register.pp

Found my answer here.  It really does seem to be an issue for some KVM test rigs:

Resolution: 

foreman-rake config -- -k idle_timeout -v 60
foreman-rake config -- -k proxy_request_timeout -v 99
