High Availability for Red Hat Virtualization Manager 4.1

Hi folks, if you missed Red Hat Summit 2017 last week, it was great time in Boston. As promised, I’m uploading my presentation on HA for RHV-M 4.1 – hosted engine. Although, I’m doing it a little differently this time. I took the time this week to actually re-record it including the demos! This way you get a flavor of how I actually presented it last week.

How to Setup HA for RHV-M pt3

Hi Folks.. the last time I left off, we had just finished setting up the initial pieces for hosted engine (RHEL configuration) in order to provide HA for RHV-M. Today we’re going to add an additional host and test things out.

Let’s get going! Continue reading “How to Setup HA for RHV-M pt3”

How to Setup HA for RHV-M pt2

Hi folks, I’m finally getting around to the high availability for RHV-M (hosted engine) walk through demo that I promised. The truth is that due to unforeseen circumstances, I had to go to “plan b”. The end result is still the same, and the workflows are almost identical, but the “in betweens” are just a bit different.

Allow me to illuminate.. Continue reading “How to Setup HA for RHV-M pt2”

How to Setup HA for RHV-M 4 pt1

Hi folks! After plowing through my home lab, I’m ready to walk you through setting up RHV-M in a “self-hosted engine” (HA) configuration. I’ve talked about this in some previous articles if you need to familiarize yourself with what the significance is or why someone might want to go with this approach over a standard deployment.

Let’s get to it. Continue reading “How to Setup HA for RHV-M 4 pt1”

RHV and DNS

Hi folks, here’s another “pre” post. What I mean by that is that in the process of creating a demo and the surrounding article, I found I needed to create a sidebar article in order to show how configure an important component. In this case, the requirement to fulfill forward and reverse name server resolution in RHV has lead me to create a basic DNS server. In this case, “dnsmasq” is a perfect solution… Continue reading “RHV and DNS”

NFS & Firewalls in RHEL 7

Here is a quick post for you guys. I’m in the midst of creating a follow up to one of my other articles and it dawns on me that I need to do this particular post first.. A post within a post, or before a post, or something. In either case, I need to provide an update to configuring NFS to poke through a firewall in RHEL 7 for the purpose of RHV in a home lab.. or other use cases. Read on, if you will… Continue reading “NFS & Firewalls in RHEL 7”

High Availability for RHV-M

Hi folks, so time ago (years?) I wrote about how to put together High Availability for RHV-M. At the time the actual configuration that I proposed was solid, if a little unorthodox. Still, it certainly left room for improvement. In this week’s post, I’m updating the configuration with something that Red Hat fully supports. They refer to the configuration as Self-Hosted Engine. Continue reading “High Availability for RHV-M”

Integrating RHV & OpenStack with Neutron

Hi folks, I recently posted an article on one of the official Red Hat blogs about the new Neutron integration between RHV and RHOSP. I have to say it’s very cool and might change the way you look at networking capabilities in RHV, at least if you’re also using RHOSP in the same data center. Continue reading “Integrating RHV & OpenStack with Neutron”

Running Cockpit inside of RHV-M

Hi Folks, if you’ve been following things for the last few months, you know RHV 4 launched last month and that one of my favorite new features is the Cockpit hypervisor admin tool. I’ve even highlighted it in 2 posts already, and I’m about to go for the “three-peat”. So what’s so cool that I needed to give it a 3rd shout out in such a short amount of time? Easy.

The ability to run it within RHV-M. Continue reading “Running Cockpit inside of RHV-M”

Live from VMworld!!

Hi folks, yup, I’m at VMworld this week. Sounds odd, huh? What exactly am I doing at VMworld, you ask? Great question. Preaching the gospel, brothers and sisters, preaching the gospel. KVM, that is…

Ok, maybe I’m laying on a bit thick. Seriously though, Red Hat has 2 booths back to back this year at VMworld – one labeled “Red Hat” as one would expect, the other labeled “Ansible”. We’re extolling the virtues of Red Hat Virtualization, CloudForms, and Ansible this year in addition to anything else that anyone wants to ask about.

That begs the question, “do folks really want to hear about Red Hat Virtualization at VMworld?” The answer is a resounding “YES”. Don’t get me wrong, there are plenty of folks at the show that won’t give us the time of day, and that’s alright. There are plenty more that come by  see demo’s of RHV. And get the shirts, hats, and stickers. Here’s a pic my colleague Jonathan G. took while I wasnt’ paying attention:

And we’re having a good time answering all the questions..
