[PATCH v3 0/3] Disable Deprecated Features by Default on s390 CPU Models
by Collin Walling 26 May '25

26 May '25

Changelog v3 - added qemu caps check to avoid breaking s390 guests trying to default deprecated_features='off' on QEMU versions that do not support reporting these features v2 - changed behavior from disabling features on the host model to instead flagging the guest CPU to disable deprecated features - removed disabling deprecated features on host model in virQEMUCapsInitCPUModelS390 - added flagging deprecated_feats in qemuProcessUpdateGuestCPU - added tests for deprecated_features='on' - split virQEMUCapsUpdateCPUDeprecatedFeatures update and qemuProcessUpdateGuestCPU changes The intention of reporting deprecated features and modifying the guest CPU model was to alleviate the user from the burden of preparing a guest with the necessary amendments to assure migration to newer hardware. While that goal was met by way of the "deprecated_features='on|off'" attribute, it still adds an extra step that the user must be aware to prepare a guest for migration and the errors that stem from an unsuccessful migration (due to feature incompatibility) is not always clear how to resolve. These patches make s390 CPU host models migration ready from the get-go by disabling deprecated features by default. They may still be disabled for other model types via the respective attribute, or reenabled if desired.

[RFC PATCH 0/2] schemas: path types refactor
by Kirill Shchetiniuk 26 May '25

26 May '25

This series of patches aims to introduce unification for path attributes in schema definitions. Previously defined types used for schema definitions are now unified into two main types: absolutePath and relativePath. This change addresses previous inconsistencies where types were sometimes used incorrectly (e.g., filePath for directory attributes). Due to prior inconsistencies, some locations now accept relative paths even if they were not explicitly intended to. To avoid such inconsistencies in the future, better names for the path types have been selected. Moreover, I suggest deprecating (with future patches) the use of relative paths in places where they are not explicitly meant to be used. This will make the schemas more consistent and, as a result, encourage users to write more deterministic XML definitions. For now the relativePath is used in such places to remain backward compatibility.

[PATCH 0/2] CH: Add support for a configuration file and log level configuration
by Stefan Kober 26 May '25

26 May '25

Similar to the qemu.conf file that allows QEMU specific configurations we add the possibility to specify a ch.conf file for Cloud Hypervisor configuration. The initial single config option is the log level, which sets the verbosity of the Cloud Hypervisor process. This allows for simpler debugging when using Cloud Hypervisor via libvirt.

[PATCH v2 0/4] domain_capabilities: add console capabilities
by Roman Bogorodskiy 26 May '25

26 May '25

Main change since v1 is adding console capabilities reporting for the libxl driver. There's also a minor cosmetic change in the qemu part to alphabetically sort VIR_DOMAIN_CHR_TYPE_* arguments for VIR_DOMAIN_CAPS_ENUM_SET(). Apparently, the only other driver reporting domain capabilities is the test driver, so it looks like all drivers are covered by this series.

[PATCH v3 0/2] Fix virtio console port assignment issue
by Aaron M. Brown 22 May '25

22 May '25

Changelog: --- v3: - Added Reviewed-By - Included CI Results Link --- v2: - Split patch into two commits - Added fixes tag --- This libvirt patch does the following: 1. fixes an issue with virtio console device port assignment on vioserial buses 2. updates console port reservation comment and changes the allowZero variable to allowPortZero for clarity Currently in libvirt, a virtio console device cannot be assigned a port number greater than zero on a vioserial bus. This leads to port collision errors when adding more than 1 virtio console device on a single vioserial bus. After applying this patch, one can add multiple console ports under a single vioserial bus. Here is a link to CI results for this series: https://gitlab.com/aaronbmalik/libvirt/-/pipelines/1831901334 Aaron M.

[PATCH v5 0/5] Adding POWER11 CPU Support
by Narayana Murty N 22 May '25

22 May '25

This patch series introduces the necessary changes to support the POWER11 CPU and POWER11 host in libvirt. Additionally, it updates the QEMU capabilities with the latest QEMU version v10.0.0 to include power11 in the capabilities tests.During testing of v2 patches found a bug in qemu which sets wrong default cpu for pre-9.0 machines, that was fixed in qemu v10.0.0. Patch Summary: Patch 0001: tests: Pin pseries-2.7 tests to the version 7.0. Patch 0002: Fix: qemuhotplugtest Set the cpu version at source as POWER9. Patch 0003: Add capabilities test support for QEMU 10.0.0 on PPC64. Patch 0004: Add POWER11 CPU model support. Patch 0005: Add POWER11 host model support. The corresponding patches for the Linux kernel and QEMU are already upstream. Relevant links are provided below: Linux kernel patches: 1. Linux P11 support: commit c2ed087ed35c ("powerpc: Add Power11 architected and raw mode") 2. Linux P11 KVM support: commit 96e266e3bcd6 ("KVM: PPC: Book3S HV: Add Power11 capability support for Nested PAPR guests") Qemu patches: 3. Qemu P11 support: commit 273db89bcaf4 ("ppc/pseries: Add Power11 cpu type") 4. Qemu P11 DD02.0 support: commit c0d964076c3e ("target/ppc: Add Power11 DD2.0 processor") 5. Qemu pre-9.0 pseries michines changing default cpu with Qemu commit 1490d0bcdfcb ("ppc/spapr: fix default cpu for pre-9.0 machines."). Note on CPU model naming: From the discussion in the community thread (https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/ICUS…) we will continue using the uppercase only for POWER11 for the CPU model name. This is consistent with the naming convention used for existing POWER models (e.g., POWER9, POWER10) in libvirt's CPU map and avoids compatibility issues with existing tooling and test expectations.

[PATCH] docs: domain: Explain supported options of 'error_policy'
by Peter Krempa 22 May '25

22 May '25

From: Peter Krempa <pkrempa(a)redhat.com> Explain what the individual settings actually result in. The changes are based on the paraprhase of qemu documentation which in 'qemu-options.hx' states: ``werror=action,rerror=action`` Specify which action to take on write and read errors. Valid actions are: "ignore" (ignore the error and try to continue), "stop" (pause QEMU), "report" (report the error to the guest), "enospc" (pause QEMU only if the host disk is full; report the error to the guest otherwise). The default setting is ``werror=enospc`` and ``rerror=report``.
