FreeBSD Jail Based Virtualization Project Completed

We're pleased to announce the completion of the foundation funded FreeBSD Jail Based Virtualization project. Here's a summary of the project by Bjoern Zeeb, the developer on the project.

I am happy to report that the funded parts of the FreeBSD Jail Based Virtualization project are completed. Some of the results have been shipping with 8.1-RELEASE while others are ready to be merged to HEAD.

Jails have been the well known operating system level virtualization technique in FreeBSD for over a decade. The import of Marko Zec's network stack virtualization has introduced a new way for abstracting subsystems. As part of this project, the abstraction framework has been generalized. Together with Jamie Gritton's flexible jail configuration syscalls, this will provide the infrastructure for, and will ease the virtualization of, further subsystems without much code duplication. The next subsystems to be virtualized will likely be SYSV/Posix IPC to help, for example, PostgreSQL users. This will probably be followed by the process namespace.

Along with the framework, debugging facilities, such as the interactive kernel debugger, have been enhanced so that every new subsystem will be able to immediately make use of these improvements without modifying a single line of code. Libjail and jls can now work on core dumps and netstat is able to query individual live network stacks attached to jails.

For the virtual network stack, work was focused on network stack teardown, a concept introduced with the network stack virtualization. The primary goal was to prototype a shutdown of the (virtual) network stacks from top to bottom, which means letting interfaces go last rather than first and still being able to cleanly shutdown TCP connections. Good progress was made, but a lot of code over the last two decades was never written in a way to be cleanly stopped. Work on this will have to continue, along with virtualizing the remaining network subsystems to allow long term stability and a leak and panic free shutdown. As a side effect, users of non-virtualized network stacks will also benefit, as other general network stack problems are identified and fixed along the way.

I am happy to see more early adopters, former OpenSolaris users, and people contributing code or reporting problems and would like to encourage people to further support this project.

My special thanks go the FreeBSD Foundation and CK Software GmbH for having sponsored this project, as well as to John Baldwin and Philip Paeps for helping with review and excellent suggestions.

Accepting Travel Grant Applications for EuroBSDCon 2010!

Calling all FreeBSD developers needing assistance with travel expenses to EuroBSDCon 2010.

The FreeBSD Foundation will be providing a limited number of travel grants to individuals requesting assistance. Please fill out and submit the Travel Grant Request Application at http://www.freebsdfoundation.org/documents/TravelRequestForm.pdf by September 3, 2010 to apply for this grant.

How it works:

This program is open to FreeBSD developers of all sorts (kernel hackers, documentation authors, bugbusters, system administrators, etc). In some cases we are also able to fund non-developers, such as active community members and FreeBSD advocates.

(1) You request funding based on a realistic and economical estimate of travel costs (economy airfare, trainfare, ...), accommodations (conference hotel and sharing a room), and registration or tutorial fees. If there are other sponsors willing to cover costs, such as your employer or the conference, we prefer you talk to them first, as our budget is limited. We are happy to split costs with you or another sponsor, such as just covering airfare or board.

If you are a speaker at the conference, we expect the conference to cover your travel costs, and will most likely not approve your direct request to us.

(2) We review your application and if approved, authorize you to seek reimbursement up to a limit. We consider several factors, including our overall and per-event budgets, and (quite importantly) the benefit to the community by funding your travel.

Most rejected applications are rejected because of an over-all limit on travel budget for the event or year, due to unrealistic or uneconomical costing, or because there is an unclear or unconvincing argument that funding the applicant will directly benefit the FreeBSD Project. Please take these points into consideration when writing your application.

(3) We reimburse costs based on actuals (receipts), and by check or bank transfer. And, we do not cover your costs if you end up having to cancel your trip. We require you to submit a report on your trip, which we may show to current or potential sponsors, and may include in our semi-annual newsletter.

There's some flexibility in the mechanism, so talk to us if something about the model doesn't quite work for you or if you have any questions. The travel grant program is one of the most effective ways we can spend money to help support the FreeBSD Project, as it helps developers get together in the same place at the same time, and helps advertise and advocate FreeBSD in the larger community.

2009 End-of-Year Fund-raising Campaign!

Since the start of our 'Be Counted!' campaign in August of this year, over 350 new and returning donors have contributed to the FreeBSD Foundation. With your help, we are now 50% of the way to meeting our 2009 fund raising goal. Thank you donors, for your support! Now, in these last few weeks of 2009, the FreeBSD Foundation needs the support of those who have yet to donate to take us the rest of the way.

The recession has hit everyone hard. For many, every possible expense has been cut, and what spending they do is out of strict necessity. Unfortunately the challenges facing FreeBSD are undiminished by recessions and the technological landscape continues to change at a rampant pace. That is why the FreeBSD Foundation nearly doubled its 2008 budget for 2009 and needs your support so we can avoid cutting our investments in 2010.

If you benefit from FreeBSD, please donate so:

development projects are funded to support emerging technologies such as solid state disks, USB 3.0, machine and network virtualization, highly parallel processors, clustering, and data replication.
BSD conferences continue around the globe.
students and contributors have the opportunity to attend conferences and developer summits.
the infrastructure of computers and equipment supporting our community can be maintained.
the FreeBSD community is grown through marketing and outreach to users and businesses.
FreeBSD trademarks are protected and the project has access to legal counsel.
FreeBSD continues to serve as the foundation for research and enterprise.

Every donation, no matter its size, makes this work possible. As a non-profit with very low overhead, your donation is the best way to invest in FreeBSD. Please make that investment today so we can meet our dual goals for 2009 of 1000 donors and $300,000.

You can make a donation (including recurring subscriptions) by going to: http://www.freebsdfoundation.org/donate/.

Be Counted Campaign!

Millions of systems run FreeBSD. Hundreds of volunteers contribute to FreeBSD's success. But what is the size of FreeBSD's user base? This simple question is very hard to answer, but its answer is vital to the cause of promoting FreeBSD. It is extremely difficult to convince businesses to invest time and money to add FreeBSD support to their products based solely on vague estimates of the size of our community. We should know - working to make FreeBSD a more widely supported platform is a task the FreeBSD Foundation has worked on since its inception.

Please help us in our fight to promote FreeBSD. A donation to the FreeBSD Foundation helps fund our work, but it also gives us strength in numbers. Our count of unique donors is a vital indication of the size and buying power of our community. However, we have never broken even one thousand donors in any year. We know in our hearts that this is a small fraction of our user base and of those who want to help expand FreeBSD's presence.

So stand up and be counted! Make a donation. Encourage other FreeBSD users to donate as well. No donation amount is too large or too small. Just by becoming a donor you are making a powerful statement about the strength of FreeBSD!
