Welcome to Fedora Weekly News Issue 165 for the week ending March 1, 2009.


In this week's issue, in announcements we're reminded about this month's 
Fedora Board meeting and updates on the Fedora 11 feature freeze and 
updates on upcoming Fedora events. News from the Fedora Planet includes 
summer internship opportunities at Red Hat, an interview with Matt 
Domsch in Red Hat Magazine, and reports from Fedora events in Egypt and 
India. In Ambassador news, many reports from the recent Southern 
California Linux Expo (SCaLE) meeting, and another update from a Fedora 
install fest in Texas. In the QA beat, updates from Fedora 11 testing 
and weekly planning, as well as helping new contributors with the 
BugZapper team. Art work brings more updates on the Echo icon theme and 
Fedora 11. In security news, updates on this week's fixes for Fedora 9 
and 10, and ongoing conversation on the security of open and closed 
source systems. Finally, the issue wraps up with updates on Fedora 11 
virtualization features, dom0 kernel experimentation, and some Q&A on 
Libvirt, VirtIO, KVM, and Xen.

---  General ---

The Fedora Board is having its monthly meeting on Tuesday March 3rd at 
1900 UTC on IRC[1].

     * Join #fedora-board-meeting to see the Board's conversation. This 
channel is read-only for non-Board members.
     * Join #fedora-board-public to discuss topics and post questions. 
This channel is read/write for everyone.

The moderator will direct questions from the #fedora-board-public 
channel to the Board members at #fedora-board-meeting. This should limit 
confusion and ensure our logs are useful to everyone.

--- Fedora 11 ---

The Fedora 11 feature freeze is coming this week[2]. Feature owners 
should update their feature's status[3] on the wiki before March 3rd, as 
the feature list will be sent to FESCo on March 6th for review.

Mass rebuilds of all packages are ongoing for Fedora 11[4]. Package 
maintainers should check[5] to see whether or not they own any packages 
that still need to be rebuilt.

Finally, we need to ensure that any hard-coded i386 architectures in 
spec files are fixed, or else the package runs the risk of not being 
built in the 32bit Rawhide repository[6].

--- General ---

Harish Pillay disected[1] an interview regarding Oracle's rebuild of CentOS.

Martin Sourada showed off[2] some Echo Icon Theme eye candy.

Jeremy Katz mused[3] on some ideas to make sharing Git repositories easier.

Daniel Walsh announced[4] a summer internship at Red Hat working on SELinux.

Jef Spaleta discussed[5] Canonical's methodology for determining its 
userbase size and relative contributions to upstream projects (compared 
to Red Hat and Fedora). Yaakov Nemoy suggested [6] that usage of the 
word "canonical" should be increased, starting with changes like 
renaming the "Fedora Packaging Guidelines" to the "Packaging Canon".

Abhishek Rane posted[7] a screenshot tour of KDE 4.2.

Joseph Smidt wrote[8] about the massive number of new Features that 
Fedora 11 is slated to contain.

Cole Robinson demonstrated[9] the Fedora 11 virt-manager "New VM" wizard.

Red Hat Magazine[10] interviewed[11] Matt Domsch to discuss the Fedora 
Mirror network.

Mark J. Wielaard explained[12] a new feature in Systemtap 0.9 that 
allows you to "collect data from any variable in scope at a probe point 
using the DWARF debug info. You can even dereference pointers, access 
struct members, array elements, etc."

--- FAD, Fedora booth at SCaLE a success ---

Fedora Ambassadors hosted a Fedora Activity Day [1] at the Southern 
California Linux Expo (SCaLE)[2] as part of the many events at the expo. 
The FAD took place on Friday, February 20th at the Westin Airport Los 
Angeles, where a group of between 12 to 20 people worked on both font 
packaging and documentation. Not only did a significant amount of work 
get done, but it was great to have a face-to-face meeting with people 
who, on a daily basis, you are in contact with via IRC or by e-mail.

One sensation at the expo was the Fedora kids who walked around the show 
floor, dressed in Fedora shirts chanting about Fedora; they were Malakai 
and Saskia Wade (daughters of Karsten Wade), Shaun Savage (son of Clint 
Savage), and Mirano Cafiero (daughter of Larry Cafiero). Also, the 
Fedora booth had XOs on hand for demonstration, and the fact the kids 
were also using them brought the attention of the general public and the 
press covering the event.

Clint Savage presented on Fedora Remix on Saturday, which was well 
attended. Several media outlets, including a reporter for the Los 
Angeles Daily News, visited the booth and interviewed Karsten Wade.

A few hundred disks and other items of swag were handed out and many 
contacts were made for upcoming presentations about Fedora at LUGs 
throughout California in the next few months.

Thanks to all those who attended FAD and who helped in the booth at SCaLE.

Here are reports from the FAD and from the Southern California Linux Expo:

--- Fedora installed by users at KGEC ---

Kalyani Government Engineering College (KGEC) is on the Kalyani 
University Campus, Kalyani in West Bengal, India, and has quite a large 
base of students interested in Linux. An install fest event [1] took 
place on Feb. 21.

This install fest is a starting point for spreading the use of Linux and 
Fedora was the distro used. Around 150 students were shown how to 
install and administer a Fedora system and were helped to get Fedora 
installed on their systems.

Reports from the following individuals are available:

     * Arindam Ghosh[2]
     * Subhodip Biswas[3]
     * Ratnadeep Debnath[4]
     * Rangeen Basu Roy Chowdhury[5]

-- Fedora at Sam Houston State University

Adam Miller gave his first tech talk[6] as a Fedora Ambassador, 
presenting to the student organization at Sam Houston State University's 
"Sam Houston Association for Computer Scientist" (SHACS for short). Adam 
introduced his fellow classmates to the wonders of Free/Open Source 
Software, Linux, and most notably, Fedora.

--- Test Days ---

This week's regular test day[1] was on CrashCatcher[2]. Zdenek Prikryl 
and Jiri Moskovcak were the developers present. Further results are 
still welcome from anyone - a full set of instructions for running tests 
is available on the Wiki page. As a result of the testing, over thirty 
issues were discovered and filed in the CrashCatcher trac system [3].

Next week's test day[4] will be on Anaconda's (the Fedora installer) 
interaction with block devices - especially RAID, LVM and encrypted 
devices. It will be held on Thursday (2009-03-05) in the #fedora-qa 
channel on Freenode IRC. Please drop by if you would like to help test 
this this area of Fedora.

--- Weekly meetings ---

The QA group weekly meeting[1] was held on 2009-02-25. The full log is 
available[2]. Josh Boyer reported epic news: the PPC build of Rawhide 
can now be successfully installed. Will Woods suggested that now is a 
good time to start putting bugs on to the tracker bug for the release of 
Fedora 11 Beta[3]. He also pointed out the tracker bug for Intel 
KMS-related issues[4]. Adam Williamson volunteered to organize a test 
day for the proposed new default NVIDIA driver, nouveau.

Will Woods and Jesse Keating discussed the progress of the autoqa 
system. Jesse would like to have more refined results output available 
soon, and a working example of a post tree-compose sanity test. Will 
Woods wants to aim to have a working verifytree test available by Fedora 
11 Beta release.

James Laska gave a progress update on the Nitrate[5] test case 
management system, mostly on working with the developers of the internal 
Red Hat system to get the code publicly available. He also promised to 
get around to proposing the Semantic system developed by the Laptop.org 
project (also discussed in last week's meeting) to the Infrastructure 
group this week.

Will Woods pointed out the Fedora 11 feature list[6] and explained that 
the QA team must ensure, by feature freeze, that all accepted features 
have a workable test process. He asked for the group's help in ensuring 
that all proposed features are checked for this and a useful test plan 
is drawn up where possible. Adam Williamson volunteered to liaise with 
the developers of the Nouveau[7] and automatic font / MIME installer[8] 

The Bugzappers group weekly meeting[9] was held on 2009-02-24. The full 
log is available[10]. There was some more discussion of goals for the 
group, and the group agreed with Christopher Beland's suggestion that 
the targetted components page[11] be updated to list the number of NEW 
bugs for each component.

Matej Cepl provided the new Greasemonkey script to add a standard 
signature to each comment posted by a Bugzapper group member[12]. John 
Poelstra wanted to have a single location for all necessary Greasemonkey 
scripts for triagers. Brennan Ashton reported that he is working on an 
RPM package which would contain Greasemonkey and the scripts.

Adam Williamson volunteered to organize a new series of triage days, to 
get the whole group together to work on triaging and training new 
members. Matej stated that he is happy to help mentor new triagers by 
email or IRC at any time.

The next QA weekly meeting will be held on 2009-03-04 at 1600 UTC in 
#fedora-meeting, and the next Bugzappers weekly meeting on 2009-03-03 at 
1700 UTC in #fedora-meeting.

--- Goals ---

Christopher Beland wrapped up the discussion on group goals[1]. "The 
official goal is now to stabilize the number of NEW bugs for each key 
component. Counts from today have been copied into that page on the 
wiki[2], and there's a preformatted query from which you can get the 
current count."

    2.  https://fedoraproject.org/wiki/BugZappers/components

--- Bugs filed against default component ---

Lex Hider pointed out[1] that the 0xFFFF component in Bugzilla gets many 
reports simply because it is the first component in the list. He 
reported that he has tried to clean up all the current reports against 
this component, and suggested creating a new component, owned by the 
Bugzappers group, to catch this problem in future.


--- QA review for feature pages ---

Will Woods asked the group[1] to work on reviewing the feature pages for 
Fedora 11, and help make sure they all have viable test procedures, as 
previously discussed at the weekly meeting. He later emphasized[2] that 
the aim is actively to help the development team produce viable test 
plans, not simply to reject or mark the features which do not yet have them.


--- Improving Bugzappers documentation for beginners ---

A new group member, Hunter Bukowski, agreed[1] with previous suggestions 
that the current Bugzappers documentation in the Wiki is not sufficient 
in quantity or organization to allow new Bugzappers to get started 
without other references. He volunteered to help improve this situation.


--- The CLA for Bugzappers ---

A new volunteer, Lalit Dhiri, introduced himself[1] and tried to join 
the FAS group for the Bugzappers team. Rahul Sundaram rejected his 
application, as he had not yet signed the CLA - the legal agreement all 
Fedora contributors are required to sign. Upon further discussion, it 
was agreed by Paul Frields and Tom 'spot' Callaway that signing the CLA 
should not be required for Bugzappers, as none of the work normally 
required in the Bugzappers group constitutes a 'contribution' to Fedora 
in this sense. The requirement for Bugzappers to sign the CLA was 
officially removed.


--- Translation ---

This section covers the news surrounding the Fedora Translation (L10n) 


Contributing Writer: Runa Bhattacharjee

--- L10n Infrastructure Team Meeting ---

The first meeting of the Fedora L10n Infrastructure team[1] was held on 
24th February 2009[2]. The discussion centered around the progress of 
the Transifex setup for Fedora 11, New features in Transifex to provide 
better statistics and submission on translate.fedoraproject.org, and 
Djamned Lies with Publican support to be ready for testing on 27th 
February. The discussion about branching of packages was marked for 
further talks with the devel team.


--- Common Content Files for Publican ---

A request for translation of Common Content files, used by Publican to 
give a uniform appearance for documents, was put forward by Ruediger 
Landmann[1]. The two files available for translation are 
Conventions.pot[2] and Feedback.pot[3]. The translated versions of these 
files are also available on the fedoraproject.org wiki[4]

--- Sponsor Upgrades Request ---

Due to a technical difficulty[1], the process of sending out 
notification messages on wiki-edits for watched pages was stalled. In 
view of this, NorikoMizumoto has requested[2] that Team Coordinators 
request sponsor upgrades via mail to the fedora-trans mailing list for 
the cvsl10n group via the fedoraproject.org wiki page[3].

--- Inconsistency in a Desktop string and GDM translations ---

IgorSoares brought forward the problem about locating a string that is 
displayed in the Fedora Gnome menu[1]. This string - About This Computer 
- was earlier translated and submitted via fedoraproject.org wiki 
page[2]. Additionally, he also raises the the issue about the 
inconsistency in the translations of GDM strings. This matter is also 
being currently discussed in a bug[3].

-- Artwork --

In this section, we cover the Fedora Artwork Project.


Contributing Writer: Nicu Buculei

--- A Lot of Folder Icons for Echo ---

MArtin Sourada contributed[1] a large number of folder icons for the 
Echo Perspective[2] set, small variations of the base folder icon "I've 
began remaking the the whole folder set to have perspective projection". 
He also wrote a blog post[3] about those icons but also about the 
evolution of the Echo theme "we like Echo and would like to see it being 
default in Fedora sometime in the future, but we also need to keep up 
with others – and that means perspective projection" and *his* own 
evolution on working on them "And how far have I gone? In short very 
far. In longer – from an occasional contributor to main contributor and 
practically the Echo Icon Theme project leader... Also as you can see 
from the images above, my inkscape skills have improved a lot ;-)"

--- Closer to Fedora 11 ---

With a bit of worry[1] ("Okay I am a bit worried at this point. I had no 
time at all this weekend to work on it, and I need to travel next 
weekend"), Máirí­n Duffy frontally attacked[2] with a number of new 
mock-ups[3] the development of the artwork for Fedora 11. Brian Hurren 
and Paolo Leoni came with useful ideas[4] [5] for the night version of 
the image.


-- Security Week --

In this section, we highlight the security stories from the week in Fedora.

Contributing Writer: JoshBressers

--- Open Source Security ---

One of the dead horses that various security folks like to beat is 
claiming that Open Source software is less secure because anyone can 
look at it and analyse its security weaknesses. So what happens when a 
system should be closed, but is suddenly broken open? Marine One Data 

It seems that Iran (the country), may have acquired sensitive 
information about the helicopter the President of the United States 
uses. When you're an organization with virtually limitless resources, 
the easy solution here is probably to just get a different helicopter, 
but suppose something similar happens to a piece of closed source 
software. Now you're at an elevated level of risk because people haven't 
been analysing your source code for weakness. Any good security system 
should still hold up even if complete details are made public. By 
purposely putting the source in public view, Open Source software has a 
very real advantage over a similar system that relies on obscurity as a

-- Virtualization --

In this section, we cover discussion on the @et-mgmnt-tools-list, 
@fedora-xen-list, @libvirt-list and @ovirt-devel-list of Fedora 
virtualization technologies.

Contributing Writer: Dale Bewley

--- Enterprise Management Tools List ---

This section contains the discussion happening on the et-mgmt-tools list

--- virt-manager Redesigned 'New VM' Wizard ---

Cole Robinson with the help of Tim Allen and Jeremy Perry started[1] 
work on a resdesign of the image:Echo-package-16px.pngvirt-manager guest 
creation wizard, because "The original design was largely based on xen 
specific assumptions and the state of libvirt/virtinst at the time: many 
of those assumptions don't apply today, or require a bit more thought 
since we now support both xen and qemu based VMs." See the post for full 
details on the long list of changes and screenshots[2].

    2.  http://fedorapeople.org/~crobinso/virt-manager/newvm2/

---- Hot Add USB Device to Guest ----

Cole Robinson answered[1] a question about hot adding a USB device to a 
running guest. The steps are "Use 'lsusb' to determine the bus and 
device", use this to create an XML snippet[2], and then feed that 
snippet to 'virsh attach-device.

--- Fedora Virtualization List ---

This section contains the discussion happening on the fedora-virt list.

---- Fedora Virt Status Update ----

Mark McLoughlin posted[1] another weekly status update including details 
on numerous virtualization developments and bugs.


--- Improved Guest Mouse Pointer Movement ---

Daniel P. Berrange announced[1] an improvement to mouse pointer movement 
in Fedora 10 and 11 KVM guests.

"The default mouse for KVM guests is a PS/2 mouse. This causes pain for 
users because it only works with relative coordinates, which means we 
are forced to grab the mouse pointer in the VNC client.

KVM can emulate a USB graphics tablet which works in absolute coordinate 
mode, and thus gives flawless mouse motion tracking without needing any 
grab in the client." [2]

USB tablet will now be used by default 
image:Echo-package-16px.pngpython-virtinst in F11.

--- Approved F11 Virtualization Features ---

Chris Lalancette relayed[1] the outcome of the FESCO meeting on February 
27[2] as it relates to virtualization.

Features approved for inclusion in Fedora 11 at this time are:

     * http://fedoraproject.org/wiki/Features/KVM_PCI_Device_Assignment
     * http://fedoraproject.org/wiki/Features/SVirt_Mandatory_Access_Control
     * http://fedoraproject.org/wiki/Features/VirtImprovedConsole
     * http://fedoraproject.org/wiki/Features/VirtVNCAuth

Deferred to Fedora 12 was:

     * http://fedoraproject.org/wiki/Features/Shared_Network_Interface
     * http://fedoraproject.org/wiki/Features/KVM_and_QEMU_merge

On the KVM and QEMU merge, Daniel P. Berrange explained[3] that "The 
QEMU upstream release will be so close to the feature freeze, that we 
don't want to risk causing KVM regressions by trying to then merge the 
two. Hopefully come F12, more of the KVM bits will be in QEMU mainline, 
so work we need todo to merge would be minimal."


--- Fedora Xen List ---

This section contains the discussion happening on the fedora-xen list.

---- dom0 Kernel Experimentation Continues ----

Michael Young made his work more accessible when he began[1] creating 
experimental dom0 kernel builds[2] within Koji. This latest kernel has 
gotten as far as booting in single user mode.

--- Libvirt List ---

This section contains the discussion happening on the libvir-list.

---- About Libvirt VirtIO and Xen ----

Patrick Archibal had a few questions[1] about virtualization and the 
relation of libvirt[2], VirtIO[3], KVM[4], and Xen[5]. Daniel P. 
Berrange took the time to provide a detailed response[6] to each of 
Patrick's questions. A selection follows.

     * What is the difference between libvirt and virtio? "libvirt 
provides a API for the host OS, allowing management of virtual machines, 
storage, networking, host devices, etc."

virtio is basically providing paravirtualized device drivers between 
guest and host, and has several aspects

     A generic infrastructure layer in guest kernel for writing device 
drivers that talk to the host
     A generic host<->guest data transport running as a PCI device
     A generic host<->guest data transport using a ring buffer
     Guest implementations for paravirt network, disk & memory balloon 
     QEMU host backends for network, disk & memory balloon drivers"

     * Why must hypervisor developers (Xen and KVM) develop drivers each 
time there are new devices? "The virtio infrastructure is intended to 
provide generic drivers that can be used on any hypervisor. Currently 
supports KVM and LGuest. Xen has its own device drivers because they 
were developed years ago outside the context of the Linux kernel 
community just for Xen's needs."

     * Can we use VirtIO with Xen?

"VirtIO is currently only supported for KVM and LGuest. It could in 
theory be implemented for Xen too, but its not clear if it is worth the

---- Encrypted VNC to Guests and TLS ----

Michael Kress wanted[1] to encrypt the session between a windows VNC 
client and a KVM guest. The thread was long with a lot of back and forth 
touching on windows clients, certificate setup, and 

Daniel P. Berrange pointed out libvirt's RemoteTLS[2] documentation and 
described[3] the Fedora 11 feature VirtVNCAuth[4] which dovetails with 
VeNCrypt[5]to "Define a mapping of SASL authentication into the VNC 
protocol, and implement it for QEMU and GTK-VNC, providing strongly 
authenticated, securely encrypted remote access of virtual guest consoles."

---- VirtualBox Support ----

Pritesh Kothari has been working[1] on adding Virtualbox[2] support to 
libvirt. Most of the functionality is complete, but Pritesh sought help 
with working out the domain XML format[3].

---- Run QEMU Guests Within a CGroup ----

Daniel P. Berrange posted[1] a proof of concept patch set with this 

"Recent Linux kernels have a new concept of 'CGroups'[2] which is a way 
to group tasks on the system and apply policy to them as a whole. We 
already use this in the LXC container driver(FWN#146[3]), to control 
total memory usage of things running within a container.

This patch series is a proof of concept to make use of CGroups in the 
QEMU driver. The idea is that we have a 3 level cgroup hierarchy

     * Top level; contains the libvirtd daemon itself
     * 2nd level: one per libvirt driver, but dos not contain any processes.
     * 3rd level: one per guest VM. Contains the QEMU process

The host admin can do control on the top level and 2nd level to set an 
overall system policy. libvirt will then provide APIs / capabilities to 
control individual VMs policy."
