There is not a whole heck of a lot that I was able to find in this area. Mayhaps it’s partly because of how KVM works. That is, VMs are naught but Linux processes and thus can be tuned the same way one tunes Linux. RedHat IBM IBM Part 2 OpenStack Linux-KVM Linux-KVM
There are times (like when you’re figuring out a post like this) that you will need to fire up devstack in a VM, and in said VM ensure KVM is running. Here’s how to do that: Add ‘vmv.allow = TRUE’ to the VMX file. I do this in vagrant like so: # VMware Fusion config.vm.provider

Having jumped from the VMware world where the memory overheads and performance characteristics of ESXi and varied workloads are well known, I was surprised to learn that such was not always true in the case of KVM. In this post we talk a bit about KVM/Qemu, and how it’s memory overhead breaks down. Understanding Memory

As I get into this performance thing with Mr Kevin. I thought I’d share a few numbers from early builds and what not. You know, the sort of “should we do this” thing kind of stuff. These nubmers are for a 5 node build using the Vagrantfiles here: Node CPU Ram Controller 1 1 1.5GB

Ok, so yesterday (two days ago now) started with “Day -1” but mayhaps I’m just an idiot, who knows. So, today’s workshop? Well, it was pretty amazing. Lots of good questions, and the lab worked for most folks. We did have some questions come up around what CLI commands we were copying/pasting during the preso

All kinds of checked into the hotel room. Speaker badge acquired, and scoped out the presentation room for tomorrow. If you haven’t already and are going to be here, you can download all of the materials here. If your hote wifi sucks, we’ll have all of this on USB keys Other Day 1 Tidbits –

tl;dr Download our OSCON lab materials here. As a follow-up on my coming to OSCON, I thought it prudent to provide some info & downloads for the lab ahead of time. Lab Materials While we will have USB keys in the tutorial for everyone, we figure some of y’all might want to get started early.

Edit: As I got a bit deeper into the copies, a new method was needed. Common First, make an image of the usb disk in question. To do this, open Disk Utility, and then: Click File Click New Click “New Image From Folder…” Select your folder Wait Next, find the image file in finder &

For those that didn’t get the messge on the twitters, I will be at OSCON this year. Specifically, I will be helping Egle run a “Getting Started with OpenStack” tutorial. The tutorial will begin with an overview of OpenStack and its different components. We will then provide access to the individual OpenStack instances to the

Installing a New Linux Kernel on Ubuntu 12.04 Whilst this may be common knowledge for those who have been working with Ubuntu for a while, it took me a few google searches to figure out, so here is the process I have settled on. sudo apt-get update # List available versions sudo apt-cache search linux-image-generic-lts

I’ve normally got at least 3-4 books I’m reading at any given point. Sometimes they’re even related to what I do. That said, I don’t much like the echo chamber that becomes my own head, so, I asked via Twitter this morning what folks are reading and came up with a few good reads: Work-ish/Business-ish

If you’ve been following along, we installed OpenLDAP here, that or you have one of your own going. Either way, the goal of this post, is to pull information out of OpenStack Keystone for import into OpenLDAP. Preparing us to transition Keystone backend over to LDAP. Getting started To get started, we’ll assume a working

After much looking about, I couldn’t actually find a decent writeup on this. At least not all in one place. So after having beat my face against it for a little while (repeatedly), I came up with the below. Installing OpenLDAP You’ll need an Ubuntu 14.04 box for this (tho, 12.04 should also work). Once

Ok, my head hurts. So much reading, watching, things to think about in regard to the application of promise theory… Wish I could promise these were light posts or so.

Some Markdown Things I’ve recently started to think about doing another book (or three if I’m to be believed). As part of that, I thought long and hard about my current workflow. What worked, what did not, and started to make some changes. One of those changes was to start writing “the things” in Markdown.

This post is by Cody Bunch. Summer VMUG Tour? – Why not? It has been at least 5 or 6 months since I was last at a VMUG, either local or otherwise. In that time, a lot of things have happened! So, why not take some time this summer and make a circuit of things.

Ran into some problems yesterday with VMware networking. It started after a few months of constantly adding and changing networks. Sometimes via Vagrant other times manually. In the end, while the VMNet networking devices would start, all of the network interfaces within the VMs were showing disconnected. Here is how I solved it: Restart Fusion
