Quack,
On behalf of the oVirt infra team, I'd like to announce the current
Mailing-Lists system is going to be upgraded to a brand new Mailman 3
installation on Monday during the slot 11:00-12:00 JST.
It should not take a full hour to migrate as we already made incremental
synchronization with the current system but better keep some margin. The
system will then take over delivery of the mails but might be a bit slow
at first as it needs to reindex all the archived mails (which might take
a few hours).
To manage your subscriptions and delivery settings you can do this
easily on the much nicer web interface (https://lists.ovirt.org). There
is a notion of account so you don't need to login separately for each ML.=
You can Sign In using Fedora, GitHub or Google or create a local account
if you prefer. Please keep in mind signing in with a different method
would create separate accounts (which cannot be merged at the moment).
But you can easily link your account to other authentication methods in
your settings (click on you name in the up-right corner -> Account ->
Account Connections).
As for the original mail archives, because the previous system did not
have stable URLs, we cannot create mappings to the new pages. We decided
to keep the old archives around on the same URL (/pipermail), so the
Internet links would still work fine.
Hope you'd be happy with the new system.

The idea was for updating XML based on policy, which is something you
want for new machines. You should then keep the XML per domain and only
do changes to if requested by the user or when libvirt fills in new
values in a guest ABI compatible fashion.

Sure, this was just meant to be a question as to whether it's worth
pursuing or not. You make a good point on why it is not (at least for
existing apps).
However, since this was optional, the way this would look without the
XML abstraction is that both input and output would be valid domain
definitions, ultimately resulting in something similar to virt-xml with
the added benefit of applying a policy from a file/string either
supplied by the application itself. Whether that policy was taken from
a common repository of such knowledge is orthogonal to this idea. Since
you would work with the same data, the upgrade could be incremental as
you'd only let virtuned fill in values for new options and could slowly
move on to using it for some pre-existing ones. None of the previous
approaches did this, if I'm not mistaken. Of course it gets more
difficult when you need to expose all the bits libvirt does and keep
them in sync (as you write below).

Oh, definitely not every, but I see two groups of projects that have a
lot in common between themselves and between the groups as well. On the
other hand just templating and defaults is something that's easy enough
to do that it's not worth outsourcing that into another one's codebase.

This is good point, but I was mostly thinking about identifying devices
=66rom the host POV between two different XMLs (pre- and post- some
XML-modifying action, like hotplug).

It definitely is, but do you think it's so difficult it's worthless to
pursuit? I did a tiny PoC based on the code from virt-manager, which
was trivial mainly thanks to the XMLBuilder for the domain objects.
Maybe exposing an easy way to work with the XML would be enough for some
projects.
Little birdie from oVirt told me that they would like some of sort of
thing that does what you can achieve with virt-xml if we, for example,
made it work on pure XML definitions without connecting to libvirt.

The initial idea (which I forgot to mention) was that all the decisions
libvirt currently does (so that it keeps the guest ABI stable) would be
moved into data (let's say some DSL) and it could then be switched or
adjusted if that's not what the mgmt app wants (on a per-definition
basis, of course). I didn't feel very optimistic about the upstream
acceptance for that idea, so I figured that there could be something
that lives beside libvirt, helps with some policies if requested and
then the resulting XML could be fed into libvirt for determining the
rest.

By native you mean actual binary libraries or native to the OpenStack
code as in python module? Because what I had in mind for this project
was a python module with optional wrapper for REST API.

I'm glad for the knowledge you provided. So maybe instead of focusing
on de-duplication of existing codebases we could _at least_ aim at
future mgmt apps. OTOH improving documentation on how to properly build
higher level concepts on top of libvirt would benefit them as well.

oVirt log analyzer
by Milan Zamazal
Hi, during last year Outreachy internship a tool for analyzing oVirt
logs was created. When it is provided with oVirt logs (such as SOS
reports, logs gathered by Lago, single or multiple log files) it tries
to identify and classify important lines from the logs and present them
in a structured form. Its primary purpose is to get a quick and easy
overview of actions and errors.
The tool analyses given logs and produces text files with the extracted
information. There is an Emacs user interface that presents the output
in a nice way with added functionality such as filtering. Emacs haters
can use the plain text files or write another user interface. :-)
You can get ovirt-log-analyzer from
https://github.com/mz-pdm/ovirt-log-analyzer
README.md explains how to use it.
Note that ovirt-log-analyzer has been created within the limited
resources of an Outreachy internship with some additional work and not
everything is perfect. Feel free to make improvements.
Regards,
Milan

[VDSM] Network test failing randomly - needs un-ordered compare?
by Nir Soffer
We have this failure in unrelated patch:
http://jenkins.ovirt.org/job/vdsm_master_check-patch-el7-x86_64/22723/con...
The issue seems to comparing strings instead of sets.
The next run was successful. I did not check if it run on the same slave.

new time-based test randomly failing

I suppose this test should be reworked, or at least, have its constants tweaked.

OST Failure - Weekly update [24/03/2018-29/03/2018]
by Dafna Ron
Hello,
I would like to update on this week's failures and OST current status.
This week I am sending the report a bit earlier due to the holidays.
We had a few failures this week but I am glad to report that the issues
were fixed quickly.
on 23-03-2018 we started getting a random failure which seems to be an
issue with the ost test hotplug_cpu
This fix was submitted by Milan to fix the issue:
https://gerrit.ovirt.org/89589
On the 27-03-2018 we had a failure on basic_sanity.disk_operations
This seems to be related to locking race and was fixed by Benny on 3
different fixes:
https://gerrit.ovirt.org/#/c/89534/
https://gerrit.ovirt.org/#/c/89537/
https://gerrit.ovirt.org/#/c/89577/
There was an issue with build-artifacts on the vdsm project which was an
infra failure as well as a code issue (2 different builds). this was also
resolved quickly.
Infra issues:
The ci team discovered and fixed a failure in container cleanup on the the
hosts. Daniel submitted this patch: https://gerrit.ovirt.org/#/c/89402/ and
it seemed to have resolved the issue.
Gal has been investigating an issue which causes failure due to lack of
memory on the host. for now, Gal submitted a fix:
https://gerrit.ovirt.org/#/c/89588/
Lastly we had a packaging issue on 4.2 which was resolved as well.
*Below you can see the chart for this week's resolved issues but cause of
failure:Code* = regression of working components/functionalities
*Infra* = infrastructure/OST Infrastructure/Lago related issues/Power
outages
*OST* Tests - package related issues, failed build artifacts
*Below is a chart of resolved failures based on ovirt version*
*Below is a chart showing failures by suite type: *
*Thanks, *
*Dafna*
