libvirtlinuxvirtualizationconsole
I’ve been wanting to automate my virtual machine instantiation for a while now,
but I’ve always hated the idea of having to spin up multiple bits of
infrastruction to deal with PXE booting, web server to host a kickstart file,
etc. Luckily, I ran into some stuff today, and figured out how to automate
virtual machine instantitation without having to resort to anything outside of
localhost.

There are always a few things I need to do to get libvirt working with a
non-root user on Fedora that I need to do, and typically results in some Google
researching. Here are some notes of what I recently did to get my libvirt setup
going on a new Fedora 25 installation and working with a non-root user.

In order to get libvirt working properly with bridged networking, we first need
to configure our local network to have network bridge slaved to our wired
ethernet adapter. I don’t have to set this up too often (as once I do, it just
sits there running happily). Here are some basic steps I did to get this going
locally.

I’ve been working on testing things with TripleO and normally I use TripleO
Quickstart to spin things up
in a virtual environment.
Often when doing NFV work though, you need things that can’t be used in a
virtual environment (such as DPDK, SR-IOV, etc) so you need some baremetal
nodes.
In my home lab environment though, I don’t have the luxury of IPMI, so I need
to make use of the fake_pxe driver in Ironic, which allows for standard PXE
control, but requires you to deal with powering on and off the machines
manually. Let me show you how I make use of that.

OpenStackLinuxCloud ComputingTripleOnfvpe
So last week I started to look into learning the new composable services and
roles
that was added to Newton. I previously learned a little bit about deploying
OpenStack clouds when I did training after joining Red Hat, but that was based
on Liberty, and a lot has changed in TripleO since that time.
The first thing was learning what composable services and roles are, and
generally what they are intended to solve. I don’t want to get into that
here, so I’d encourage you to go read some links first and then come back here.
Additionally, it’s assumed you know what a TripleO is :)

Recently I’ve gotten into running as many of my day-to-day applications in a
Linux console. Thought I’d briefly share the applications I’ve been playing
with.

This page documents and provides bullets about the way to approach (or avoid)
building products. These are lessons we’ve learned from previous encounters and
which we wish to avoid in the future. By sticking firmly to these development
rules, we avoid getting bogged down in complete system rearchitectures in the
future. The means to a scaled end is to approach the first customer as all your
customers.

AstriCon At AstriCon 2015 this year, there was a lot (and I mean a lot) of discussion around microservices (Docker), and what effort is required over the next year by the development community in order to make Asterisk better suited to running in that environment.
One of the first things is, clearly, to have a container image that Asterisk runs in. I’ve done this a few times now, but having something that can be passed over to the official Asterisk Git repository, and which everyone can contribute to, utilize and play with would be the goal here.

We have a small system running in AWS as a CentOS 7 image. It has a few
containers that we’re using to host a few Golang API proxies. We migrated a
customers API proxy that was running on the local VM into a container, and spun
it up. Upon testing, we ran into the following error:
x509: failed to load system roots and no roots provided

So the documentation for
Powerline kind of
sucks. I followed
this pretty good
article on getting started with it. First thing I noticed however is that the
if statement on the article doesn’t work if you don’t have powerline
installed (which kind of defeats the purpose of having the if statement there
at all).
