[PATCH 00/17] qemu: Fix regresion when loading internal snapshots and few cleanups
by Peter Krempa 16 May '25

16 May '25

This series: 1) Fixes the regression in loading internal snapshots: https://gitlab.com/libvirt/libvirt/-/issues/771 2) Fixes bugs in cleanup paths of snapshot reversion where we'd keep an inactive transient VM definition in the domain list (Noticed when debugging the former issue) 3) Cleans up qemu commandline generator of unneeded arguments for snapshot reversion after recent removal of old code 4) Renames the argument used to revert internal snapshots to something more obvious. 5) Cleans some unneeded passing of the qemu driver struct Peter Krempa (17): qemuProcessStartWithMemoryState: Don't setup qemu for incoming migration when reverting internal snapshot NEWS: Mention fix for internal snapshot reversion regression qemuSnapshotRevertActive: Remove transient domain on failure qemuSnapshotRevertInactive: Ensure all error paths handle transient domains properly qemuBuildCommandLine: Drop 'snapshot' argument qemuProcessLaunch: Rename 'snapshot' to 'internalSnapshotRevert' qemuProcessStart: Rename 'snapshot' to 'internalSnapshotRevert' qemuProcessStartWithMemoryState: Rename 'snapshot' to 'internalSnapshotRevert' qemuExtDevicesCleanupHost: Use 'virQEMUDriverConfig' instead of 'virQEMUDriver' qemuCheckpointDiscardAllMetadata: Remove 'driver' argument qemuSnapshotDiscardAllMetadata: Remove 'driver' argument qemuDomainRemoveInactiveCommon: Remove 'driver' argument qemuProcessStop: Drop 'driver' argument qemuDomainRemoveInactiveLocked: Remove 'driver' argument qemuProcessReconnect: Modernize local variable setup qemuProcessReconnectData: Drop 'driver' struct and clean up qemuDomainRemoveInactive: Remove 'driver' argument NEWS.rst | 10 ++++ src/qemu/qemu_checkpoint.c | 5 +- src/qemu/qemu_checkpoint.h | 3 +- src/qemu/qemu_command.c | 5 +- src/qemu/qemu_command.h | 1 - src/qemu/qemu_domain.c | 25 +++++----- src/qemu/qemu_domain.h | 6 +-- src/qemu/qemu_driver.c | 46 ++++++++---------- src/qemu/qemu_extdevice.c | 18 +++---- src/qemu/qemu_extdevice.h | 4 +- src/qemu/qemu_migration.c | 20 ++++---- src/qemu/qemu_process.c | 98 +++++++++++++++++++------------------- src/qemu/qemu_process.h | 7 ++- src/qemu/qemu_saveimage.c | 2 +- src/qemu/qemu_snapshot.c | 75 ++++++++++++++--------------- src/qemu/qemu_snapshot.h | 3 +- src/qemu/qemu_tpm.c | 14 ++---- src/qemu/qemu_tpm.h | 4 +- 18 files changed, 167 insertions(+), 179 deletions(-) -- 2.49.0

[PATCH v3 0/6] qemu: acpi-generic-initiator support
by Andrea Righi 16 May '25

16 May '25

= Overview = This patch set introduces support for acpi-generic-initiator devices, supported by QEMU [1]. The acpi-generic-initiator object is required to support Multi-Instance GPU (MIG) configurations on NVIDIA GPUs [2]. MIG enables partitioning of GPU resources into multiple isolated instances, each requiring a dedicated NUMA node definition. = Implementation = This patch set implements the libvirt counterpart to the QEMU feature, enabling users to configure acpi-generic-initiator objects within libvirt domain XML. This includes: - adding XML syntax to define acpi-generic-initiator objects, - resolving the acpi-generic-initiator definitions into the proper QEMU command-line arguments, - ensuring compatibility with existing NUMA configuration. = Example = - Domain XML: ``` ... <cpu mode='host-passthrough' check='none'> <numa> <cell id='0' cpus='0-15' memory='8388608' unit='KiB'/> <cell id='1' memory='0' unit='KiB'/> <cell id='2' memory='0' unit='KiB'/> <cell id='3' memory='0' unit='KiB'/> <cell id='4' memory='0' unit='KiB'/> <cell id='5' memory='0' unit='KiB'/> <cell id='6' memory='0' unit='KiB'/> <cell id='7' memory='0' unit='KiB'/> <cell id='8' memory='0' unit='KiB'/> </numa> </cpu> ... <devices> ... <hostdev mode='subsystem' type='pci' managed='no'> <source> <address domain='0x0009' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x03' slot='0x00' function='0x0'/> </hostdev> <acpi-generic-initiator> <alias name="gi1"/> <pci-dev>hostdev0</pci-dev> <numa-node>1</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <alias name="gi2"/> <pci-dev>hostdev0</pci-dev> <numa-node>2</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <alias name="gi3"/> <pci-dev>hostdev0</pci-dev> <numa-node>3</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <alias name="gi4"/> <pci-dev>hostdev0</pci-dev> <numa-node>4</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <alias name="gi5"/> <pci-dev>hostdev0</pci-dev> <numa-node>5</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <alias name="gi6"/> <pci-dev>hostdev0</pci-dev> <numa-node>6</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <alias name="gi7"/> <pci-dev>hostdev0</pci-dev> <numa-node>7</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <alias name="gi8"/> <pci-dev>hostdev0</pci-dev> <numa-node>8</numa-node> </acpi-generic-initiator> </devices> ``` -

[PATCH v2 0/3] Add virt machine support for configuring PCI high memory MMIO size
by Matthew R. Ochs 15 May '25

15 May '25

This patch series adds support for configuring the PCI high memory MMIO window size for aarch64 virt machine types using the highmem-mmio-size feature introduced in QEMU v10.0.0 [1]. It allows users to configure the size of the high memory MMIO window above 4GB, which can be required to support PCI passthrough with devices that have a large BARs. The feature is exposed through the existing pcihole64 element associated with the PCIe root controller: <controller type='pci' index='0' model='pcie-root'> <pcihole64 unit='GiB'>512</pcihole64> </controller> This existing schema supports the same semantics for the QEMU PC machine pci-hole64-size parameter and is a natural fit for supporting the highmem-mmio-size feature on the aarch64 virt machine. This series is applied over master and depends on the recently merged patch [2] that added support for QEMU v10.0.0 aarch64 capabilities. For your convenience, this series is also available on Github [3].

[PATCH 0/7] Fix return type of some functions
by Michal Privoznik 15 May '25

15 May '25

Inspired by Peter's patch: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/TRQ3… (since it wasn't merged yet, one hunk in patch 7/7 is the same as Peter's; I'll update it after Peter merges his patches) There are some function which are declared to return an int, but in fact return a boolean: int foo(...) { ... return true; } Worse, some mix ints and bools. With a help of coccinelle I was able to identify some offenders. And either redeclare them to return a bool, or fix those (misleading) return statements.
