Why Mess Around with libvirt?

You might have noticed that I’ve been writing a fair number of articles around libvirt, the open source virtualization API project. Here are some of the libvirt-related articles that I’ve posted over the last couple of months (and there are more in the works):

Wrapping libvirt Virtual Networks Around Open vSwitch Fake Bridges

In a previous article, I talked about how to use Open vSwitch (OVS) fake bridges to bring VLAN support into your environment. In this article, I show you how to wrap a libvirt virtual network around your OVS fake bridge.

VLANs with Open vSwitch Fake Bridges

In other posts, I’ve (briefly) talked about how to configure Open vSwitch (OVS) for use with VLANs. If you know the port to which a guest is connected, you can configure that particular port as a VLAN trunk like this:

OVS, of course, is central to the strategy and functionality of several network virtualization players and projects:

Managing Your E-mail Inbox

I tweeted earlier today that I managed to achieve “Inbox Zero” (an empty e-mail inbox) while at a major industry conference (I’m in Spain for VMworld EMEA). A follower on Twitter asked if I would share my “inbox secret”. It’s not a secret, really, but I thought I’d share it here just in case others are interested in trying to emulate a similar methodology (or are just interested in getting control of your e-mail inbox).

Technology Short Take #25

Welcome to Technology Short Take #25, my irregularly-published collection of links, articles, thoughts, and rants. It’s been a while since my last Technology Short Take (almost three months!); my apologies for that. This is my first time publishing a Technology Short Take with my new filesystem-based approach of managing resources. We’ll see how well it goes
