Xen and KVM Discussion from Ian Pratt

May 9th, 2008 by Stephen Spector

I read a blog posting on the web today at zdnet with comments from Ian about Xen and KVM. I don’t normally post any type of “political” thoughts on this blog but I thought Ian’s comments are worth reading for the community. You can read the article at http://blogs.zdnet.com/virtualization/?p=415.

I think the title of the article is a bit overstated but is the usual media looking for a controversy.

Xen-API Community Project Update

May 8th, 2008 by Stephen Spector

The kickoff meeting for the Xen-API community project is scheduled for May 15, 2008 at 4pm EST. I am still looking for people interested in working on this project and the meeting is open to all Xen.org community members. I will be posting all meeting minutes and activities on the Xen Wiki once the project is underway so attendance at the meetings is not mandatory; however, the first few meetings will be important as we discuss what work items need to be complete and people get a chance to volunteer.

The dial-in information for the meeting is:

A potential list of topics:

* Review and/or provide deep insight into the fundamentals of specific virtualization technologies

Xen Name History Finally Solved

May 7th, 2008 by Stephen Spector

For those of you tracking my “History of Xen” blog series, I am proud to announce that we finally have the story of where “Xen” came from - check out this comment. 

New Security Email for Xen.org

May 5th, 2008 by Stephen Spector

A new email has been established for anyone finding a security issue with any Xen build. Please send a detailed email of the problem to security@xen.org. This email distribution reaches a wide group of Xen community members who can immediately address the problem.

Xen Summit Final Call for Topics

May 1st, 2008 by Stephen Spector

I am adding two more weeks for open submissions of topics for Xen Summit Boston. May 16 will be the official close of topic submissions so the Program Committee can create the final agenda. Please send your topic request to stephen.spector@xen.org with a brief abstract and title.

Thanks to everyone who already has submitted a topic, the Program Committee will begin reviewing all current submissions next week.

Xen-API Community Project

April 28th, 2008 by Stephen Spector

Several community members have contacted me recently about the Xen-API utilities. I looked into this and discovered a great opportunity for community members looking for a project to contribute to. So, I am announcing a new community effort to complete the development of the Xen-API utilities. If you are interested in working on the Xen-API project please email me at stephen.spector@xen.org and I will call a meeting in mid-May with all people interested to get the project underway.

NOTE - This interface is not to be seen as a replacement for the existing XML-RPC interface and people should not infer anything by this project.

Here are some thoughts on the importance of the Xen-API if you are considering joining this community effort:

  • Xen-API cleans up a lot of the cruft of the older APIs
  • Authentication aspect to the Xen-API allows the API to be used off-box securely
  • Xen-API’s event registration / dispatch piece is much better than the old API, making it much easier to build web GUIs or health monitors
  • The Xen-API has two mechanisms, one for synchronous task invocation, and a congruent one for asynchronous tasks. This means, for example, that you can reboot a VM, and either block waiting for it to complete, or get a task handle and poll back later. This gives application developers the freedom to choose how they interact with Xend
  • Xend will get a code update from this project and will give developers a chance to learn more about xm as well as Xend (Xend is written in Python)
  • Xen-API already has C and Python bindings in the Xen tree; Ruby bindings are also rumored to exist

Running Xen book hits the streets!

April 23rd, 2008 by Boris Quiroz

As the tittle says Running Xen: A Hands-on Guide to the Art of Virtualization is now available to buy, physically of course. So, if you want a copy just follow this link to find out how to get it.

There’s also a complementary website where you can find information about the authors, chapters resources and some other interesting links. Obviously, the authors want some feed back, that’s why they set up a readers list to discus about the book, send your feed backs, errata, and any other topics related to the book.

Nothing else to say. Congratulations to the authors for the great job they did.

Xen Summit Boston - Are you coming?

April 21st, 2008 by Stephen Spector

The Xen Summit Program Committee is actively reviewing all the submitted topics for this event (we still want more topics - send to Stephen Spector) and I wanted to make everyone aware of a proposed agenda for the event along with some topics already approved. The proposed agenda, current topics, and Monday evening party information are at http://xen.org/files/xensummitagenda.pdf.

If you are on the fence about coming to Xen Summit, please let me know what topics you would like presented and how I can make the event more attractive to you. As Xen.org is a community-based project, I want to ensure that everyone in the community is able to voice their opinion and there is no better place to be heard than Xen Summit!

Want to know more about Boston in the Summer - check out this posting.  For a Top 10 List of things to do in Boston this Summer, go here. Of course, all these great things to do in Boston are for before and after Xen Summit as there will be enough content during the event to keep you plenty busy :)
