QEMU boot of raw GPT partition
by Pedro Francisco
Hello!
I'm considering the hypothesis of booting a raw GPT partition on QEMU.
I was pondering basing my attempt on:
https://wiki.archlinux.org/index.php/QEMU#Simulate_virtual_disk_with_MBR_....
Basically, I would create a fake GPT partition table (actually, two, since
they are mirrored at the end of the disk), manually calculating the start
point of the partition I want to start.
I would like to avoid including on this disk the Linux partitions, hence
the need for such calculations.
Anyone here ever tried anything similar?

Strange problem -
by Bob Goodwin
Fedora 20 64 bit XFCE
When logging out from gui I get:
"Received error while trying to log out
Session manager must be in idle state when requesting a shutdown."
Each time I reboot a number of windows/tabs are loaded, I go through and
close them all.
However there is garbage running when I look at ctrl-alt-F1 and XFCE is
in ctrl-alt-F2.
There must be a command to kill everything but I haven't found it.
Need help please,
Bob

building a driver/mod for a wireless nic
by bruce
Hi.
I know this is a "centos" issue, but I've searched, can't find an
answer, and thought the answer might be helpful to others. Feel free
to flame away if I stepped on your toes!
I'm following the steps to build the driver/module as describe in the url
http://elrepo.org/tiki/wl-kmod
The step I'm confused on is the step 4)
4) Download the Broadcom driver matching your architecture (i.e.,
32-bit vs 64-bit):
from: http://www.broadcom.com/support/802.11/linux_sta.php
to: ~/rpmbuild/SOURCES/
The tar.gz file for the driver is listed on the page, but I'm not sure
if I'm supposed to place the entire tar.gz file in the "SOURCES" dir
(doubtful) or if i'm supposed to untar it, which will then have the
underlying dirs from the tar file in the SOURCES dir...
Or, if I'm supposed to follow the readme listed on the broadcom page,
and build the wl.ko.
Once I get this resolved, the rest should work ok...
Thanks for any pointers/feedback.

NTP slowing down system shutdown, how to disable?
by Eric Smith
I'm using a Dell T3500 running Fedora 20 x86_64. It's on a private network
not connected to the Internet, and with no NTP server. When I shut down the
machine, it pauses for more than a minute at
A stop job is running for NTP client/server.
I don't think I enabled NTP when I installed it, but I've done
systemctl disable ntpd.service
and the same for ntpdate and sntp, but it still pauses for that stop job.
Why is it doing that, and what can I do to make it skip that? I'm having a
hard time learning the ins and outs of systemd.
Thanks!

NM bridging releted problem
by Cristian Sava
My servers & desktops were working ok with F19 and F20 (new or
upgraded).
After the recent updates on F20 NM does not start br0 on boot.
I succeed to connect to the net after manually restarting NM.
Is it something wrong with my setup? Any advice? Is it a known bug? Do I
need to fill a bug report?
(I know I can restart NM in rc.local but ...)
I did not tested it on F19 with latest updates.

IPv6 breakage in NetworkManager
by Dan Irwin
Hi all,
Seeing significant issues with IPv6. After some time, IPv6 completely seems
to stop working. IPv4 is unaffected.
Re-connecting to wifi seems to restore IPv6 connectivity.
However, various things (ssh, firefox) stop working completely. Open ssh
sessions "freeze". Web page requests time out.
At the same time, I can access IPv6 resources from other machines which do
not run NetworkManager.
Next time this occurs, I hope to have some time to diagnose this problem
further. In the meantime, is anyone else seeing such breaking wrt IPv6?
Something to note, I run numerous servers with IPv6, both physical and
virtual. These servers run CentOS; None run NetworkManager, and all have
working IPv6 connectivity.
Cheers,
Dan

Fedora 19 Freezes
by linuxnutster@videotron.ca
I have been getting a lot of freezes in Fedora 19, usually once the
screensaver kicks in for a while, but also at the login prompt and when
using firefox. The most recent freeze involved the screensaver. It
simply locked up with the screensaver image frozen and still visible.
The mouse cursor was locked and there was no activity. I ran a memtest
and hard drive tests and everything came back fine.
I do remember seeing several ABRT messages regarding the nvidia driver
I'm using being a proprietary driver ...etc... some open source
programmers hate proprietary drives... something along that end. I
recently had surgery and was having trouble paying attention. ABRT also
no longer seems to function, and I have updated to the latest kernel and
video drivers.
Where do I look for log entries to enable troubleshooting, and has
anybody else experienced this? Any help would be appreciated.
