[PATCH] spec: Do not disable some systemd units of newly split package
by Martin Kletzander 14 Jul '23

14 Jul '23

Since virtproxyd was split into libvirt-daemon-proxy package it can happen that, in case a distribution has such systemd preset, when installing this package, already pre-enabled and configured units like -tls.socket and -tcp.socket will get disabled. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2210058 Fixes: 5358618b1cd0afc126aed313249bf2134731665f Signed-off-by: Martin Kletzander <mkletzan(a)redhat.com> --- This is more like an RFC as I would really like to know what to really do in this case. What happens, basically, is that if you have libvirt-daemon-9.0.0 and set up virtproxyd-tls.socket for example and then upgrade to anything newer, then the package libvirt-daemon-proxy will get installed. The %post action calls "%libvirt_daemon_systemd_post_inet virtproxyd" which calls "%systemd_post with all virtproxyd units. What %systemd_post is supposed to do is reset units to a preset state in the case of package installation, but not during upgrade. However the libvirt-daemon-proxy package did not exist on the system before, so this action is not an update, but an installation. If no preset is mentioned for a unit then `systemctl preset` does not change anything. However some distros might have a catch-all preset "disable *" for some reason, I guess based on an example in the documentation, and there is no way to override an already configured preset, you can only enable or disable a unit in a preset. That all means than it can happen that you enable virtproxyd-tcp.socket, for example, then update your system and find that it is disabled. There are various ways to deal with this, but I don't see any one that would 100% satisfy me with regards to all the issues and at the same time could be implemented "soon enough" given libvirt already had three releases with the libvirt-daemon-proxy split. libvirt.spec.in | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 1f77cd90b772..50f521b7ce88 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1592,7 +1592,13 @@ fi %post daemon-proxy %if %{with_modular_daemons} -%libvirt_daemon_systemd_post_inet virtproxyd +# Since this was split into a different package, a transparent update for the +# virtproxyd units could actually disable an already configured ones +# (e.g. virtproxyd-tls.socket) as %systemd_post runs `systemctl preset` if this +# is an installation (and is skipped on update).

[libvirt PATCH 00/10] A set of minor doc updates for new contributors
by Tim Small 14 Jul '23

14 Jul '23

As a prospective contributor, whilst the documentation is generally very helpful, I found a few minor gaps and inconsistencies. I thought I would strike while the iron was hot, and attempt to make some improvements. The changes are mostly minor clarifications, and additional internal references between articles. The only new material is a guide to using clangd with the libvirt code base (since clangd has become a common programming tool, and is particularly useful for navigating unfamiliar code bases). On build hosts where gcc is the default compiler, some manual steps are necessary before clangd will work with the libvirt code, and I thought these were worth documenting. Tim Small (10): docs: Link to main docs directory from Quick Links docs: Missing "full-stop"/"period" on some bullet items docs: Link main "contributing" from programming-specific guide docs: Point to compiling guide from code contribution guide docs: Add config instructions for clangd with libvirt docs: Reword "Preparing Patches" to clarify docs: Advise running CI tests prior to submission docs: Point to mailing list archives from submitting-patches docs: Fix deprecated use of implicit meson "setup" command docs: Reword ninja invocation note to clarify build directory docs/clangd.rst | 51 +++++++++++++++++++++++++++++++++++++ docs/compiling.rst | 14 +++++----- docs/contribute.rst | 6 ++--- docs/hacking.rst | 29 ++++++++++++++++++--- docs/index.rst | 2 ++ docs/meson.build | 1 + docs/submitting-patches.rst | 5 ++++ 7 files changed, 96 insertions(+), 12 deletions(-) create mode 100644 docs/clangd.rst -- 2.39.2

[PATCH] qemu_domain: Deduplicate targetNode check in qemuDomainDefValidateMemoryHotplugDevice()
by Michal Privoznik 13 Jul '23

13 Jul '23

If a domain has NUMA configured, then all <memory/> devices (except for 'virtio-pmem') need to have targetNode set. There are two checks inside of qemuDomainDefValidateMemoryHotplugDevice() for this: one inside of big switch() statement, which only checks 'dimm' and 'nvdimm' cases, and the other at the end of the function that checks all models (except for 'virtio-pmem'). Let's keep the latter and remove the former as the latter covers the former too.

[libvirt PATCH] docs: index: Add a quick link to Submitting patches
by Erik Skultety 13 Jul '23

We still get MRs in Gitlab from individual contributors on a regular basis which in some ways just makes maintainer's or reviewer's life just a bit more complicated. This ultimately means our guidelines are probably not visible enough on the main page (or some people wouldn't read them anyway). While this patch can't make the problem go away, it can at least attempt to mitigate it by creating a quick link to the 'hacking' page, skipping a lot of TL;DR contents in contributing.rst which we link from the main page.

[PATCH] libxl: Defer starting job until migration perform phase
by Jim Fehlig 13 Jul '23

13 Jul '23

Currently the libxl driver calls virDomainObjBeginJob in the begin phase of migration on the source host, expecting to call virDomainObjEndJob in the confirm phase. But the confirm phase is never executed if the prepare or perform phases fail. The job was already being terminated in the perform phase in case of failure, but there is no way to do that if the prepare phase fails since it runs on the destination host. Move the call to virDomainObjBeginJob to the perform phase. It can be terminated there in the event of failure. On success, the confirm phase will be executed, ensuring the job is terminated.

[PATCH] node_device: Enclose Linux specific code in ifdef __linux__
by Michal Privoznik 12 Jul '23

12 Jul '23

Our CI started to enable udev backend on FreeBSD. And while there is udev on FreeBSD some parts of our code are highly Linux specific, e.g. translating SCSI device type to string (from an integer obtained from the sysfs). Obviously, this doesn't work anywhere else. This is the reason why we need to include scsi/scsi.h header file (which actually comes from the Linux kernel source tree but for some reason glibc started to distribute it, followed by musl).

[PATCH v2 0/5] Migration deprecated parts
by Juan Quintela 07 Jul '23

07 Jul '23

On this v2: - dropped -incoming <uri> deprecation Paolo came with a better solution using keyvalues. - skipped field is already ready for next pull request, so dropped. - dropped the RFC bits, nermal PATCH. - Assessed all the review comments. - Added indentation of migration.json. - Used the documentation pointer to substitute block migration. Please review. [v1] Hi this series describe the migration parts that have to be deprecated. - It is an rfc because I doubt that I did the deprecation process right. Hello Markus O:-) - skipped field: It is older than me, I have never know what it stands for. As far as I know it has always been zero. - inc/blk migrate command options. They are only used by block migration (that I deprecate on the following patch). And they are really bad. grep must_remove_block_options. - block migration. block jobs, whatever they are called this week are way more flexible. Current code works, but we broke it here and there, and really nobody has stand up to maintain it. It is quite contained and can be left there. Is anyone really using it? - old compression method. It don't work. See last try from Lukas to make a test that works reliabely. I failed with the same task years ago. It is really slow, and if compression is good for you, multifd + zlib is going to perform/compress way more. I don't know what to do with this code, really. * Remove it for this release? It don't work, and haven't work reliabely in quite a few time. * Deprecate it and remove in another couple of releases, i.e. normal deprecation. * Ideas? - -incoming <uri> if you need to set parameters (multifd cames to mind, and preempt has the same problem), you really needs to use defer. So what should we do here? This part is not urget, because management apps have a working option that are already using "defer", and the code simplifacation if we remove it is not so big. So we can leave it until 9.0 or whatever we think fit. What do you think? Later, Juan.

Release of libvirt-9.5.0
by Jiri Denemark 03 Jul '23

03 Jul '23

The 9.5.0 release of both libvirt and libvirt-python is tagged and signed tarballs and source RPMs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * New features * qemu: Allow configuring the ``discard-no-unref`` feature of ``qcow2`` driver The new ``discard_no_unref`` attribute of the ``disk`` ``driver`` element controls whether the ``qcow2`` driver in qemu unrefs clusters inside the image on discard requests. Disabling cluster unrefing decreases fragmentation of the image. * Improvements * qemu: Include maximum physical address size in baseline CPU When computing a baseline CPU definition for a set of hosts, we need to include maximum physical address size in the result to make sure it is compatible with all hosts even if their supported physical address sizes differ. * conf: Properly handle slots for non-DIMM ``<memory>`` devices Memory devices such as ``virtio-mem`` don't need a memory slot as they are PCI devices. ``libvirt`` now properly accounts the memory slots for such devices as well as specifying the ``slots`` attribute of the ``<maxMemory>`` element is no longer needed unless DIMM-like devices are to be used. * ``passt`` log and port forwarding improvements Libvirt now ensures that the ``passt`` helper process can access the configured log file even when it's placed in a directory without permissions. The ``<portForward>`` element of a passt-backed interface can now omit the ``address`` attribute as it's enough to specify a ``dev``. * Bug fixes * lxc: Allow seeking in ``/proc/meminfo`` to resove failure with new ``procps`` package New version of the ``free`` command from ``procps`` package seeks into the ``/proc/meminfo`` file, which was not supported by the instance of the file exposed via LXC causing a failure. * qemu: Fix rare race-condition when detaching a device The device removal handler callback function didn't re-check the state of the unplug operation after a timeout, which could rarely cause that the device was removed from the VM but not the definition. * qemu: Fix NUMA memory allocation logic QEMU allocates memory via the emulator thread thus that has to be allowed to access all configured NUMA nodes of the VM rather than just the one where it's supposed to be pinned. * qemu: Fix setup of ``hostdev`` backed ``<interface>`` The proper steps to initialize the host device were skipped for interfaces due to a logic bug preventing start of VM which used them. Enjoy. Jirka
