- Fedora Weekly News Issue 182 -

Welcome to Fedora Weekly News Issue 182[1] for the week ending June 28, 
2009.

Here are a few highlights from this week's issue. By request, we've 
returned to including the contents at the top of the issue.  Please let 
us know what you think!  Announcements starts us off with updates on 
recent Fedora elections. Hot on the heels of the release of Fedora 11, 
the codename for Fedora 12 has already been chosen -- read inside for 
details. From the Fedora Planet, lots of great updates from the recent 
FUDCon in Berlin, as well as many updates from Fedora contributors. In 
Ambassador news, details from the recent Fedora 11 launch party from the 
NaLUG (Napoli GNU/Linux Users Group). In Quality Assurance news, many 
updates on Fedora 12 development, including discussion of improving 
debugging procedure pages, rawhide acceptance plan, bugzapper updates, 
and much more. Much interesting discussion in the Design beat this week 
on thinking around themes for Fedora 12 based on the release name. In 
Security Advisories, we're brought up to date with this week's software 
patches for Fedora 9, 10 and 11. This week's issue rounds out with 
updates from virtualization activities, with detail work on a libguestfs 
'Super-minimized Appliance', VMWare ESX driver status, and much more! Enjoy!

aggregation of blogs from Fedora contributors worldwide.

--- General ---

Joseph Smidt requested[1] that all Linux distributions report bugs 
upstream: "Now, assuming each major Linux distribution has hundreds of 
bugs where the bug triager knows it is an issue with upstream but fails 
to report it, if all these bugs would get reported I am sure an extra 
100 bugs will get fixed over the next six months because of simple 
things like this."

Mel Chua packaged[2] his first RPM, making notes along the way of where 
documentation was lacking: "I’m actually quite impressed by how simple 
the process is, and how helpful the resources are - however, my baseline 
for “easy process!” is “it’s better than several weeks of blindly trying 
to install Linux for the first time via stacks of floppies in 2001!” so 
just because it’s “good enough” doesn’t mean it’s as good as it could be.

How can we improve this experience?"

Jeff Sheltren was interviewed[3] for the FLOSS Weekly podcast.

Dan Williams showed off[4] how easy it is to connect to a mobile 
broadband connection using NetworkManager. In a later post, he 
described[5] the differences between NetworkManager and ConnMan.

John Palmier attended[6] the Open Video Conference[7]. "The web was 
built and exploded around the concept of open technology. Let’s continue 
to make sure this is the case going forward. The last thing we want is 
the web to become the domain of a few, with creativity being stifled by 
restrictions in the non-open parts of the stack."

Adam Jackson explained[8] how computers (try to) identify the 
capabilities (resolutions, refresh rates, etc...) of monitors by 
following the EDID standard. And a new partially-compatible standard, 
DisplayID that is set to replace EDID.

Jack Aboutboul announced[9] Project FooBar. While still in the early 
stages, there are 5 main goals: "Centralization of Content, well 
scheduled, recurring and prepared content, design which is consistent 
with the philosophy of the Design team, standardized "official" feeds 
for distribution of different forms of content, mechanisms for 
localization and sharing the media with press or on social news sites."

Matthew Garrett complained[10] about the lack of openness at Intel. 
While some parts of the company seem committed to Linux and Open Source, 
other parts (notably EFI and Poulsbo) don't always integrate as nicely 
with Linux as some might prefer.

Adrian Reber analyzed[11] the Fedora mirror server traffic, for the few 
days following the Leonidas release. Pretty graphs ensued.

Aaron S. Hawley compared[12] cars to software (though he is certainly 
not the first to do so) by quoting a post that described the ability to 
take apart, modify and maintain one's own car, despite the fact that 
when it comes to software, often that ability is missing.

Aaron also posted[13] a piece about "How the [IT] culture is hostile to 
women". See also: FUDCon Attendee Photo[14].

Dave Malcolm wondered[15] where the word "codebase" came from.

Joshua Wulf wrote[16] about the challenges involved with "Neologisms and 
Localization". Is "Parameterized" a word?

James Morris described[17] some of the upcoming changes to the security 
subsystem in kernel 2.6.30.

--- Release event in Naples ---

Gianluca Varisco reports on a Fedora 11 release event in Naples, Italy, 
recently. NaLUG (Napoli GNU/Linux Users Group) organized, in 
collaboration with UDU Parthenope (Unione degli Universitari), the 
Fedora 11 Release Party. The location was simply perfect: a building 
property of Parthenope’s University, located in the hearth of Naples.

For more on the event, visit 
http://www.techtemple.org/2009/06/26/fedora-11-release-party-in-naples-italy/

--- Get the word out about your F11 event ---

Fedora 11 was released on Tuesday, June 9, and with it a variety of 
activities around the release will be forthcoming. As such, with the 
upcoming release of Fedora 11, this is a reminder that posting your 
event on Fedora Weekly News can help get the word out. Contact FWN 
Ambassador correspondent Larry Cafiero at 
lcafiero-AT-fedoraproject-DOT-org with announcements of upcoming events 
-- and don't forget to e-mail reports after the events as well.

-- QualityAssurance --

In this section, we cover the activities of the QA team[1].

Contributing Writer: Adam Williamson

--- Test Days ---

There was no Test Day last week.

Currently, no Test Day is scheduled for next week - it is still very 
early in the Fedora 12 cycle. If you would like to propose a test day 
which could result in changes for post-release updates for Fedora 11, or 
an early test day for Fedora 12, please contact the QA team via email or 
IRC, or file a ticket in QA Trac[1].

    1. ↑ https://fedorahosted.org/fedora-qa/

--- Weekly meetings ---

The QA group weekly meeting[1] was held on 2009-06-24. The full log is 
available[2]. James Laska reported that he had not yet been able to 
update the QA Goals page[3], due to lack of time.

Will Woods provided an update on the Rawhide acceptance test plan. The 
plan is now available on the Wiki[4], with ten suggested test cases. 
Tickets have been filed to track the creation of each test case. He 
asked for anyone who was interested in this project to help write or 
review the test cases. Jóhann Guðmundsson suggested adding a test case 
for basic network functionality, and the others present agreed with this 
suggestion.

James Laska reviewed the new schedule for Fedora 12 QA events which has 
been submitted by John Poelstra[5]. He pointed out several changes he 
felt were positive. The group discussed whether Test Day dates should be 
added to the main QA schedule, but in the end decided they should not be.

Will Woods gave a quick further update on the status of AutoQA (which 
includes the rawhide acceptance testing discussed earlier). He explained 
that, once the test plans were written, it should be relatively easy to 
automate them via autotest, and automation of some tests should be 
complete in one or two weeks. James Laska noted that Jesse Keating had 
sent a link to a presentation he would be giving on AutoQA[6], and asked 
for feedback to be sent to the list.

Finally, Jóhann Guðmundsson proposed a project to improve the quality 
and quantity of information contained in bug reports[7]. Will Woods 
noted that abrt[8], the automated bug reporting tool, will allow the use 
of plugins to configure what files or other information should be 
attached to reports from particular components.

The Bugzappers group weekly meeting[9] was held on 2009-06-23. The full 
log is available[10].

The meeting was dominated by a discussion of the status of the project 
to integrate anaconda triage better into the BugZappers process, and to 
introduce kernel triage. Andy Lindeberg and Peter Jones provided 
valuable information on the anaconda process. After much discussion, it 
was broadly agreed that there was no broad incompatibility between the 
anaconda bug process and the BugZappers process, and with a small amount 
of work, the two could be integrated: a good list of required 
information for anaconda bug reports should be created, it should be 
made clear that anaconda reports must be assigned to a specific anaconda 
maintainer and this assignment confirmed in person via IRC or email 
before being made, and volunteers to triage anaconda should already be 
well versed in its workings, or receive some training before beginning 
to triage actively.

The next QA weekly meeting will be held on 2009-06-31 at 1600 UTC in 
#fedora-meeting, and the next Bugzappers weekly meeting on 2009-06-30 at 
1500 UTC in #fedora-meeting.

--- Test Day shepherding SOP draft ---

Adam Williamson announced[1] a draft SOP for the process of running a 
Test Day[2], with the intent of making it easier for more people to run 
Test Day events.

--- Improvement of debugging procedure pages ---

The recap mail for the QA meeting provoked a thread[1]about the best way 
to improve the quality of information contained in bug reports. 
Eventually, several members of the group decided to improve existing 
pages explaining how to accurately identify and categorize bugs, and 
what information to include when reporting them, for various components. 
Work started with the page on X.org[2]. François Cami made some initial 
improvements[3], Christopher Beland followed these up with some further 
tweaks and suggestions[4], and Adam Williamson contributed some further 
additions and addressed Christopher's suggestions.

-- Artwork --

In this section, we cover the Fedora Design Team[1].

Contributing Writer: Nicu Buculei

--- Theming Constantine ---

 From FUDCon, after the announcement of the release name for Fedora 12 
Nicu Buculei launchedref[1] the talks about the graphic theme of the 
next release "I am sure you are all already aware, the announcement is 
official since yesterday when Paul delivered in in front of the FUDCon 
audience, the release name for Fedora 12 was voted Constantine". He also 
proposed a possible approach: Byzantine mosaics "When I think about it, 
I had in my mind Byzantine culture (Roman emperor Constantine the Great) 
and I think a graphic in the style of a Byzantine mosaic can be an 
effective approach. The major trick is to leave out any religious 
implications and stay only with cultural references."

Joost Elfering invited[2] everyone to think at the big picture "I think 
we need to take a step back before coming up with results and examples. 
i suggest we first take a look at the associations with Constantine. 
these associations will be the bases for out new style. so no examples, 
just conceptual works" and showed concerns about the religious 
implications "this theme is really heavily based on religion on it's 
own. We will probably have some angry faces just because of the name. 
keeping out religion on this one will be really hard!", concerns 
shared[3] also by Konstantinos Antonakoglou "You can't expect any work 
of art without a religious reference" who proposed a simple take on that 
"So, to keep it simple I sense that we should say: 'Hey! Byzantine art 
used the mosaic art! Let's use it too.'"

Henrik Heigl chimed-in[4] with his own concerns about aggressiveness 
"The Lion has a bit of an aggressive meaning, Constantine is en emperor 
(also a bit aggressive) do we want the same way or make something 
smoother?" and added another couple of ideas to the brainstorming "I 
also had the Logo of my old University" and "Also I had the the "Lion" 
we had in Fedora11 in my head and now maybe another animal", with the 
animal idea ruled-out[5] quickly by Nicu "We can't go with another 
animal (no, not even a panda :D), that would be to close to the previous 
release."

-- Virtualization --

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

--- Enterprise Management Tools List ---

---- Remote virt-manager VM Wizard ----

Craig Miskell was[1] "running image:Echo-package-16px.pngvirt-manager 
0.7.0 on Ubuntu, connecting using SSH to [a remote] 
image:Echo-package-16px.pnglibvirt running on Debian Lenny Xen-3.2.1", 
and when attempting to create a new guest found "no install options are 
available because:"

     * "Network install" is not available unless the connection is 
local, and
     * Local install media and Network boot (PXE) are not available 
because of the following line in create.py (around line 340):

is_pv = (self.capsguest.os_type == "xen")

Cole Robinson pointed out the latter has been fixed upstream, and 
explained the former fails "Because a network install has to fetch a 
boot kernel and initrd from the URL, and we have no way to tell the 
remote machine to fetch these locations."

--- Fedora Virtualization List ---

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

---- F12 Feature: Host Information ----

Richard Jones posted[1] an RFC for a feature[2] he's working on for 
Fedora 12. The feature will "Allow a virtual machine to see information 
and statistics from the host operating system."

For example, it will "Allow a virtual machine to look at host 
information (such as number of physical, not just virtual CPUs), and 
statistics like the load on the host."

Daniel Berrange noted[3] that "a core goal of this hostinfo service is 
to avoid any use of networking. We don't want to presume that a guest 
has a NIC, nor that the host has a configured NIC on the same LAN as the 
guest." So this feature will make use of serial ports to pass queries 
and responses between the guest and the host.

---- libguestfs Super-minimized Appliance ----

Richard Jones created[1] a set of "very experimental" patches to 
image:Echo-package-16px.pnglibguestfs "which allow you to build a 
so-called 'supermin (super-minimized) appliance'."

Within libguestfs, "The normal appliance is a self-contained Linux 
operating system, based on the Fedora/RHEL/CentOS Linux distro. So it 
contains a complete copy of all the libraries and programs needed, like 
kernel, libc, bash, coreutils etc etc."

"The supermin appliance removes the kernel and all the executable 
libraries and programs from the appliance. That just leaves a skeleton 
of config files and some data files, which is obviously massively 
smaller than the normal appliance. At runtime we rebuild the appliance 
on-the-fly from the libraries and programs on the host (eg. pulling in 
the real /lib/libc.so, the real /bin/bash etc.)"

"The new appliance is a mere 500K, so libguestfs RPMs will be a lot 
smaller. Of course that just means they will have many more 
dependencies, so the amount pulled down will be the same or greater."

---- A guest fish in the pipes ----

Richard Jones patched[1] image:Echo-package-16px.pngguestfish. "This 
patch adds support for pipes to guestfish, so you can pipe output from a 
guestfish command through a command on the host. The canonical example is:

<fs> hexdump /bin/ls | less

Another example, looking for root backdoors in the password file:

<fs> cat /etc/passwd | awk -F: '$3 == 0 { print }' | grep -v ^root:

Anything right of the first pipe symbol gets passed to the local shell, 
thus expansion, redirection and so on work on that."

--- Libvirt List ---

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

---- Safe PCI Device Passthrough ----

Mirko Raasch asked[1] "How can i start my guest with three pci devices 
passed through and image:Echo-package-16px.pnglibvirt?" Starting qemu by 
hand appeared to work. But virsh start produced an error:

  libvirtd: 15:44:55.459: warning : pciTrySecondaryBusReset:483 : Other
devices on bus with 0000:05:01.0, not doing bus reset

Daniel Berrange recalled[2] "what libvirt is complaining about is that 
there are other devices in the PCI bus which are not associated with 
this guest, and thus there is no way to safely reset the device you are 
trying to assign, without endangering the host OS or other guest OS."

Adding "when you launch QEMU manually there is no checking for whether 
the PCI devices are in use by other guests, or by the host OS. So while 
it may launch QEMU, it is not running safely, and eg, if your guest OS 
does a PCI bus reset it could kill/harm your host OS."

PCI device passthrough is a new feature[3] in Fedora 11.

---- VMware ESX driver status update ----

Matthias Bolte continued[1] work (FWN #177[2]) to create a VMware ESX 
driver for libvirt.

Matthias is currently "working on the VMX config to domain XML mapping 
for dump/create XML" using the VMware Infrastructure API[3].
