Entering freeze for libvirt-9.1.0
by Jiri Denemark
I have just tagged v9.1.0-rc1 in the repository and pushed signed
tarballs and source RPMs to https://libvirt.org/sources/
Please give the release candidate some testing and in case you find a
serious issue which should have a fix in the upcoming release, feel
free to reply to this thread to make sure the issue is more visible.
If you have not done so yet, please update NEWS.rst to document any
significant change you made since the last release.
Thanks,
Jirka

[PATCH 0/1] CI: Add scheduled job for container update and regenerate with new lcitool
by Peter Krempa
As it was intended and discussed before I've added a scheduled job named
'Weekly CI container rebuild' which will run the pipeline with
RUN_CONTAINER_BUILDS variable set to 1 to update the containers
regularly rather than doing it manually and very infrequently.
The job will run every Monday at 5AM UTC.
I'll trigger it manually tomorrow if there are no objections.
Note that gitlabs scheduled job permissions are weird so I'm not sure
who will be able to edit or delete the job in the future. I can't do
that for the daily build with coverity.
The patch also regenerates the CI files with latest lcitool

[GSOC 2023] Contribution Request
by dihia bendjenahi
Hello,
I am Dihia Bendjenahi, a 4th year computer science student at The Higher
National School of Computer Science of Algiers, Algeria. I am specialized
in computer systems. I came across Libvirt's projects list for GSOC and I
was really interested by the "Metadata Support For All Object Schemas"
project. I have worked on multiple projects throughout my studies and I
used different data structures, datatypes, programming languages and data
formats to deal with data. I have been working with C language since I was
in high school (for around 6 years now) and I wrote tens of projects
ranging from simple small projects to complex programs.
I would love to know whether I can start working on my proposal for this
particular project, and I would also love to get your thoughts about what
to do next and how to get started with Libvirt.
I would really appreciate your help.
I'm sorry to disturb you and thank you for your time.
Looking forward to hearing from you soon.
Cordially

[PATCH v2] Deprecate the "-no-acpi" command line switch
by Thomas Huth
Similar to "-no-hpet", the "-no-acpi" switch is a legacy command

[libvirt PATCH v5 00/32] Use nbdkit for http/ftp/ssh network drives in libvirt
by Jonathon Jongsma
This is the fifth version of this patch series. See
https://bugzilla.redhat.com/show_bug.cgi?id=2016527 for more information about
the goal, but the summary is that RHEL does not want to ship the qemu storage
plugins for curl and ssh. Handling them outside of the qemu process provides
several advantages such as reduced attack surface and stability.
See previous series for more info:
https://listman.redhat.com/archives/libvir-list/2022-October/235052.html
Note that gitlab CI will not work for this series without changes to the ci
definitions due to the addition of libnbd dependency. It also will require
changes to selinux policy to enable nbdkit to execute in the proper context.
Changes in v5:
- securely erase secrets, including in virCommand send buffers
- don't kill a running guest when restarting libvirt if we can't properly
initialize nbdkit state
- make sure to restart nbdkit when libvirt restarts if nbdkit has died in the
meantime
- simplify ownership of event data used for monitoring and restart of nbdkit
process
- other smaller changes suggested by Peter in v4
Jonathon Jongsma (32):
schema: allow 'ssh' as a protocol for network disks
qemu: Add functions for determining nbdkit availability
qemu: expand nbdkit capabilities
util: Allow virFileCache data to be any GObject
qemu: implement basic virFileCache for nbdkit caps
qemu: implement persistent file cache for nbdkit caps
qemu: use file cache for nbdkit caps
qemu: Add qemuNbdkitProcess

qemu: add functions to start and stop nbdkit
qemu: remove unused 'mode' param from qemuDomainLogContextNew()
Generalize qemuDomainLogContextNew()
qemu: Extract qemuDomainLogContext into a new file
qemu: move qemuProcessReadLog() to qemuLogContext
qemu: log error output from nbdkit

util: make virCommandSetSendBuffer testable
tests: add tests for nbdkit invocation
qemu: add test for authenticating a https network disk
qemu: Monitor nbdkit process for exit

schema: add password configuration for ssh disk
qemu: implement password auth for ssh disks with nbdkit
schema: add configuration for host verification of ssh disks
qemu: implement knownHosts for ssh disks with nbdkit
schema: add keyfile configuration for ssh disks
qemu: implement keyfile auth for ssh disk with nbdkit

[PATCH 0/1] RFC for allowing updating some disk driver
by jshen28
QEMU has provided QMP blockdev-reopen to allow reconfigure some
driver properties while virtual machine is running. Such properties
are including cachmode, detect-zeroes and discard. This PS modifies
update-device a little bit to allow updating those properties.
