[PATCH 0/9] qemu: Move config validation out of qemu_process.c

Some more cleanups for misplaced validation of config that I've noticed when I was looking for the code validating floppies in my previous series.

[PATCH v2 0/3] CH: Add support for a configuration file and log level configuration
by Stefan Kober 27 May '25

27 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 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 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.
