[CentOS-virt] Difference between qemu-kvm-ev and qemu-kvm-ma?

[Lance Albertson]

I see with the introduction of CentOS 7.5 there's a new qemu-kvm-ma package
on ppc64le (which is actually newer than qemu-kvm-ev currently). Does
anyone know what the difference is between these two packages? We currently
use qemu-kvm-ev and we've run into this bug [1] which got me wondering if
we should be switching to that package on ppc64le.

Thanks!

On the one hand, it's certainly not too late - we're trying to figure out
what to do *before* it happens, so we don't run around like chickens with
their head cut off when it does.

On the other hand... static, and unchanging, right, and how many minutes
of Amazon S3 will it take to break the encryption?

Probably not going to have them seeded today.  Debuginfo in progress
right now and there are a bunch of things that need to be added to the
extras repositories for docker/cloud/atomic that are priority for right now.

I’ve checked about a dozen of the mirrors, and see no *.torrent files yet.  Any 
idea how long they’ll take to appear?  I ask because we’re building a system 
today, so if it’s going to be more than a few hours, I’ll grab the ISO file 
directly, but otherwise, I’d prefer to spread the load.

Probably too late for consideration at this point, but there are Enterprise
Class SSDs available with DoD/NSA certified/approved self encryption
capability.  The concept is that encryption is a hardware feature of the
drive, when you want to dispose of it, you throw away the key.  This allows
vendors to receive broken drives back from GOV/MIL clients securely so that
failure methods can be researched.

Dell and EMC have been presenting this to us at storage briefs for a couple
of years now.

[CentOS] CentOS-announce Digest, Vol 159, Issue 2

[centos-announce-request]

 to version 2018.03 to support more boards
- we have now variants other than "minimal" (so GNOME and KDE)
- selinux is working in enforcing mode and not in permissive mode by
default so there is no need anymore to relabel filesystem and reboot)

We have also changed the way we built the armhfp images, so please
consider reading the dedicated wiki page to understand which steps are
now mandatory to ensure that your armhfp will boot correctly (basically
setting up uboot)

More informations/details on the dedicated wiki page :
https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp

== Getting help
If you are searching for help, or would like to help the CentOS
altarch/armhfp ecosystem, feel free to subscribe to the CentOS arm-dev
list (https://lists.centos.org/mailman/listinfo/arm-dev) or chat with us
in #centos-arm on irc.freenode.net

== Special thank you message
I'd like to say thank you to Pablo Greco, who helped a lot for this
release, with all the hard work he did during the CentOS 7.4.1708 days
to catch up with all the packages that weren't able to build, work that
permits now to have a armhfp release set as close as possible with the
upstream x86_64 one. Kudos !

I am pleased to announce the general availability of CentOS Linux 7
(1804) for across all architectures. Effectively immediately, this
is the current release for CentOS Linux 7 and is tagged as 1804, derived
from Red Hat Enterprise Linux 7.5

As always, read through the Release Notes at :
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 - these notes
contain important information about the release and details about some
of the content inside the release from the CentOS QA team. These notes
are updated constantly to include issues and incorporate feedback from
the users.

Updates, Sources, and DebugInfos

Updates released since the upstream release are all posted, across all
architectures. We strongly recommend every user apply all updates,
including the content released today, on your existing CentOS Linux 7
machine by just running 'yum update'.

As with all CentOS Linux 7 components, this release was built from
sources hosted at git.centos.org. In addition, SRPMs that are a
byproduct of the build (and also considered critical in the code and
buildsys process) are being published to match every binary RPM we
release. Sources will be available from vault.centos.org in their own
dedicated directories to match the corresponding binary RPMs. Since
there is far less traffic to the CentOS source RPMs compared with the
binary RPMs, we are not putting this content on the main mirror
network. If users wish to mirror this content they can do so using the
reposync command available in the yum-utils package. All CentOS source
RPMs are signed with the same key used to sign their binary
counterparts. Developers and end users looking at inspecting and
contributing patches to the CentOS Linux distro will find the code
hosted at git.centos.org far simpler to work against. Details on how
to best consume those are documented along with a quick start at :
http://wiki.centos.org/Sources

Debuginfo packages are also being signed and pushed. Yum configs
shipped in the new release file will have all the context required for
debuginfo to be available on every CentOS Linux install.

This release supersedes all previously released content for CentOS
Linux 7, and therefore we highly encourage all users to upgrade their
machines. Information on different upgrade strategies and how to
handle stale content is included in the Release Notes.

Note that older content, obsoleted by newer versions of the same
applications are trim'd off from repos like Extras/ and Plus/ However
this time we have also extended this to the sIG content hosted at
mirror.centos.org, and some older End of Life content has been dropped.
Everything we ever release, is always available on the vault service for
people still looking for and have a real need for it.

In order to conserve donor bandwidth, and to make it possible to get
the mirror content sync'd out as soon as possible, we recommend using

[CentOS] Video troubles after 7.5 upgrade using CR repo

[Nicolas Kovacs]

Hi,

Our desktop clients are running CentOS 7 with the Xfce desktop from
EPEL. The CR repository is enabled. A few days ago I launched an update,
which brought in close to 1 GB of packages.

I had some weird problems on two clients. One is an old Dell Optiplex
330 with a legacy video card.

[root@cybermule:/] # lspci | grep -i vga

01:05.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] RC410 [Radeon Xpress 200/1100]

After the update, X wouldn't start anymore, and there was no way to make
it behave. I had to reinstall everything and disable the CR repo (or
more precisely not enable it in the first place). After this, things
went back to normal.

On another desktop client, a more recent Dell Optiplex 780, this is what
the video card looks like.

[root@littlesister:/] # lspci | grep -i vga

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset
Integrated Graphics Controller (rev 03)

On this machine I have some weird screen artefacts. When opening a
window - any window - there is a sort of a black flash. Meaning the
window is a black square, and then the content appears.

Plus, on LibreOffice, when doing things like modifying tabs in a
document, the tab lines are persistent all over the screen. Very ugly,
and the secretary complains about not being able to work correctly.

Any idea what's happening here? Until now, CentOS 7 never gave me this
sort of headaches.

Cheers,

Niki

[CentOS-announce] Release for CentOS Linux 7 (1804) on armhfp

[Fabian Arrotin]

I am pleased to announce the general availability of CentOS Linux 7
(1804) for armhfp compatible machines.

This is the current release for CentOS Linux
7 and is tagged as 1804, derived from Red Hat Enterprise Linux 7.5

== Download
You can download new images for armhfp boards on

== What's new (specific to armhfp)
As before, CentOS 7 userland for armhfp is still built from the CentOS 7
distribution, with some modified, added (or removed) packages.

Here are some highlights for the 7.5.1804 release :
- Kernel (for both rpi2/3 and generic boards) was bumped to 4.14.x (LTS
version) to also follow the i386 AltArch kernel.
- uboot images were updated to version 2018.03 to support more boards
- we have now variants other than "minimal" (so GNOME and KDE)
- selinux is working in enforcing mode and not in permissive mode by
default so there is no need anymore to relabel filesystem and reboot)

We have also changed the way we built the armhfp images, so please
consider reading the dedicated wiki page to understand which steps are
now mandatory to ensure that your armhfp will boot correctly (basically
setting up uboot)

== Special thank you message
I'd like to say thank you to Pablo Greco, who helped a lot for this
release, with all the hard work he did during the CentOS 7.4.1708 days
to catch up with all the packages that weren't able to build, work that
permits now to have a armhfp release set as close as possible with the
upstream x86_64 one. Kudos !
