Hi Folks, recently my friend and colleague, Tony James prepared and delivered an excellent webinar internally at Red Hat on how to configure Open Virtual Networking (OVN) in Red Hat Virtualization. For those of you that are unfamiliar with OVN, or what it offers, allow me to provide you with the proper illumination. Continue reading “Introduction to OVN and Red Hat Virtualization”
Hi folks, one of the many things that I’ve been working on behind the scenes has finally seen the light of day: Best Practices for Red Hat Virtualization 4. This takes over where the product documentation leaves off. Continue reading “Best Practices for RHV 4”
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. Continue reading “High Availability for Red Hat Virtualization Manager 4.1”
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”
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”
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”
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”
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”
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”
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.
