Recording: how to setup provisioning for development

lzap · October 5, 2017, 2:01pm

Hello,

although I know that forklift provides basic provisioning setup, this
is only for nested environment which does not work for me (e.g.
discovery livecd is booting up about an hour on my system in nested).
We had a one hour head-to-head meeting with Rahul and I created
recording of that discussing how to set things up for development of
bare-metal provisioning with libvirt, DNS, DHCP, TFTP and git
checkouts of foreman and proxy - basically without Forklilft.

Might be useful for someone who is interested in this. Some links I
use in the video:

# Katello provisioning setup

A role is included which will configure an all-on-one provisioning environment
with Katello. It uses nested libvirt to make your virtual machine a hypervisor
capable of running it's own VM's.  It also sets up a private NAT network on the
host.

## How to configure

1. Enable nested virt on your phyiscal box.  See http://www.rdoxenham.com/?p=275
comments for more details.  Essentially, add this line to kvm-intel.conf and
reboot:

        echo "options kvm-intel nested=1" | sudo tee /etc/modprobe.d/kvm-intel.conf

2. Build a box

    - Option 1: Use the `centos7-provision-nightly` box.

    - Option 2: Use an existing katello box (e.g. centos7-katello-p4-nightly) and run the provisioning playbook (it takes a while, as it syncs (on-demand) centos7, puppet 4).   ***Note*: If you are using puppet 4, you need to increase the ram on the box, to something like 8096 otherwise candlepin crashes with OOM.**
