Xen Directions Slides and Videos

I completed the new Xen Directions page on at Not all the slides and videos are availalable yet as I need approval from the speakers to post both; however there is some interesting information already available. As the speakers get back to me over the next few days I will update the page links.

All the presentation slides are in English and the only video in German is Frank Kohler from Citrix; however, his slides are excellent and worth a look.

Xen Directions Europe Highlights

I am busy working on putting slides and videos up from the Xen Directions event held this past Saturday at LinuxTAG in Berlin. To hold you over, here are some images from the event.

From the ConVirt team…

Some of the highlights of this release are:

Virtual Network Management
Support for creating isolated and NAT-based networks on managed hosts. Each virtual network can have a pre-defined IP range, with automatic DHCP provisioning of IP’s for all attached VM’s.

Automation using CLI
This release of ConVirt includes a preview version of CLI. Most common operations available via ConVirt GUI can now be done using a command line. This enables users to automate their management tasks across the whole virtualized deployment.

Ability to add disks to running VM
This release adds ability to add disks to running Xen Virtual machines.

Interview with Thomas Morgan, CEO Zerigo, inc

In keeping with my occasional interview with companies that use open source Xen – I would like to introduce Thomas Morgan from Zerigo, inc.

Who is Thomas Morgan?

I’m the CEO and founder of Zerigo, Inc. My personal interests, in the realm of technology, include automation, virtualization, APIs and integration, and user experience. I’m able to work on all of those these days and it’s a lot of fun.

Tell me more about Zerigo?

Zerigo is focused on higher-performance, higher-reliability hosting.
Our flagship offering is our Xen VPS hosting. We also offer managed DNS hosting and server monitoring–both with feature sets catering to VPS users (whether on our VPS service or not). More broadly, we tend to offer services and features that are desirable to more technically- inclined users. To that end, we try to listen really well too.

How do you use open source Xen?

It powers our VPS service, so that’s pretty significant by itself. We also use it for a ton of our internal operations too, as we gain operational efficiency from the flexibility of a virtual environment.

Why is open source Xen important?

Open source software is such a market disruptor, I think people are crazy to ignore it–that includes virtualization software. I find the culture around open source projects to be substantially different than traditional commercial software. Open source software projects tend to be designed to be used with other products and are more easily used and extended in ways not originally envisioned. For Zerigo this is crucial as we continue to bring new features and new takes on old features to the marketplace. It’d be much harder to lead in that kind of way if our hands were tied by the typical closed source software stack.

How do you contribute to the community?

We encourage everyone at Zerigo to participate in giving back to the various communities that enable our success–many of which are communities surrounding the variety of open source projects we use. I personally tend toward helping answer people’s questions about using Xen or whatever other project they’re asking about. Most frequently this is in an IRC channel or blog posting, but sometimes it’s in mailing lists or forums too. I also try to help in identifying bugs and fixing them. We’re always up for providing resources to help worthy open source projects too.

Do you have any offer for the Xen community?

How about 10% off our VPS services? Promo code is xenorg10.

New Site for Review

Xen Community:

As many of you know, the current website requires a great deal of work to keep updated as it consists of a series of html text files. Last year, I worked with several community members to create a better layout within the existing structure to assist web users in finding information in a sensible manner.

I am now taking the next step in porting the existing web structure to a hosted model where I am able to edit and manipulate the site without text files and a great deal of CSS knowledge. This new tool also allows for simple design changes with a point and click and tighter integration with social networking tools.

Please take a look at the new site and add your feedback in the Comments or directly to me.

Finally, please remember that not all sites such as the Wiki, Mailing Lists, or Bugzilla have the new look & feel as that requires additional effort and I want to get community buy-in on the new site first.
