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! 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, if you came out to Red Hat Summit, I hope you had a great time. If you were unable to attend, I’ve pulled together some links to some presentations that you might find interesting. I’ve kept them relevant to this blog – KVM or managing KVM based technologies. Continue reading “What you missed at Red Hat Summit 2016”
A few weeks ago, I made a suggestion/push/case for what I casually refer to as “cloud light”. As a brief recap, it just means using a hybrid management platform (aka cloud management platform) to front a traditional virtualization platform like RHEV. In the end, you get automation, integration, self-service, API and everything else you would want from “private cloud”. See my previous article on Should I Migrate to the Cloud? for the “why” or “why not”..
Before we get to our “cloud light”, we need to start by deploying our traditional virtualization. In this case, “RHEV”. Continue reading “Deploying RHEV 3.6 pt1”
I get this question about cloud a lot. Sometimes in those exact words, sometimes in a longer and more drawn out fashion. The answer?
Yes. It just depends on your definition of cloud. Continue reading “Should I Migrate to “the Cloud”?”
In our last post, we took a look at the hot add CPU feature for Red Hat Enterprise Virtualization. It wasn’t a brand new feature, but still very important, especially when paired with Hot Add Memory. Which actually is a brand new feature… Continue reading “Hot Adding Memory to RHEV”
Lots and lots of good things happening in my little corner of the world.. I’m happy to report that here will be much more RHEV content coming up over the next several months due to a new role that I’m taking on. This will include much more time to write and ultimately help all of you out again. Feel free to hit me up in the comments for RHEV-related things that you think might interest you. I can’t guarantee that I will get to all of them, but I’ll try to incorporate what I can.
Thanks for being patient.
In the last 2 posts we covered creating a custom cloud image for RHEL, then editing it with “guest fish”. Today, I’ll introduce you to another tool called “oz” as we continue our journey into creating custom cloud images. The way we did things last time using “virt-manager” is fine if you’re doing an image here or there.. but let’s face it, walking through anaconda is cumbersome. Granted, I showed you how to do things using the CLI and kickstart, but I think you’ll like this way even better. Continue reading “Custom Cloud Images for OpenStack pt3”
