[PATCH v3 0/8] Enable mshv support for Qemu domains
by Praveen K Paladugu 17 Oct '25

17 Oct '25

"[PATCH v3 00/26] Implementing a MSHV (Microsoft Hypervisor) accelerator" patchset in qemu-devel mailing list introduces MSHV support within Qemu. With above patchset, Qemu guests can be started with `-accel mshv` option to use Microsoft Hypervisor (/dev/mshv) as the hypervisor. Retaining Libvirt's naming convention, this translates to `hyperv` domains. Below is an excerpt of the xml to use with this patchset: ``` <domain type='hyperv'> <name>qemu_msh_testv</name> <cpu mode='host-model'/> <os> <type machine='q35'>hvm</type> </os> ... ``` This patch set introduces the necessary changes within libvirt to support Qemu guest with hyperv (mshv) hypervisor. Chages in v3: - Addressed review comments on v2. - fixed qemucapabilitiestest case - Added a case to qemuxmlconftest Changes in v2: - Addressed review comments on v1. - Added a test to verify mshv capabilities. Praveen K Paladugu (8): qemu: introduce mshv capabilities qemu: use mshv accel for hyperv domains qemu: add /dev/mshv to default cgroup acl qemu: probe mshv capabilities conf: update capability schema tests: Add mshv variant for qemucapabilitiestest tests: Add domaincaps and qemucaps case for mshv tests: add mshv test to qemuxmlconftest src/conf/schemas/capability.rng | 1 + src/qemu/qemu.conf.in | 2 +- src/qemu/qemu_capabilities.c | 61 +- src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 2 +- src/qemu/qemu_command.c | 4 +- src/qemu/qemu_monitor.c | 12 + src/qemu/qemu_monitor.h | 12 +- src/qemu/qemu_monitor_json.c | 32 +- src/qemu/qemu_monitor_json.h | 13 +- src/qemu/test_libvirtd_qemu.aug.in | 3 +- .../qemu_10.1.0-q35.x86_64+mshv.xml | 222 + .../qemu_10.1.0-tcg.x86_64+mshv.xml | 1810 + .../qemu_10.1.0.x86_64+mshv.xml | 222 + tests/qemucapabilitiesdata/README.rst | 5 + .../caps_10.1.0_x86_64+mshv.replies | 46912 ++++++++++++++++ .../caps_10.1.0_x86_64+mshv.xml | 4996 ++ .../qemucaps2xmloutdata/caps.x86_64+mshv.xml | 29 + ...86_64-q35-headless.x86_64-latest+mshv.args | 48 + ...x86_64-q35-headless.x86_64-latest+mshv.xml | 87 + ...mshv-x86_64-q35-headless.x86_64-latest.err | 1 + .../mshv-x86_64-q35-headless.xml | 35 + tests/qemuxmlconftest.c | 5 + 23 files changed, 54495 insertions(+), 20 deletions(-) create mode 100644 tests/domaincapsdata/qemu_10.1.0-q35.x86_64+mshv.xml create mode 100644 tests/domaincapsdata/qemu_10.1.0-tcg.x86_64+mshv.xml create mode 100644 tests/domaincapsdata/qemu_10.1.0.x86_64+mshv.xml create mode 100644 tests/qemucapabilitiesdata/caps_10.1.0_x86_64+mshv.replies create mode 100644 tests/qemucapabilitiesdata/caps_10.1.0_x86_64+mshv.xml create mode 100644 tests/qemucaps2xmloutdata/caps.x86_64+mshv.xml create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.x86_64-latest+mshv.args create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.x86_64-latest+mshv.xml create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.x86_64-latest.err create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.xml -- 2.50.1

[PATCH v3 0/7] USB hostdev: allow addressing by port
by Maximilian Martin 16 Oct '25

16 Oct '25

Currently, only vendor/product and bus/device matching are supported for USB host devices. Neither of these provide a stable and persistent way of assigning a guest a specific host device. Vendor/product can be ambiguous. Device numbers change on every enumeration. This patch adds a bus/port matching, which allows a specific port on the host to be specified using the dotted notation found in Linux's "devpath" sysfs attribute. The path series is based on the previous work of Thomas Hebb: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/message/7U3… This resubmission includes Daniel's patch which extends the USB hostdev test logic. Maximilian Martin (7): tests: validate an XML config with USB vendor/product set virusb test data: add devpath files for port addressing domain_conf, virhostdev, virusb, virusb test: add bus/port matching schema: add USB port attribute tests: validate an XML config with USB bus/port set nodedev: add USB port to nodedev XML docs: add description for USB port matching docs/formatdomain.rst | 29 ++-- src/conf/domain_conf.c | 58 ++++++- src/conf/domain_conf.h | 1 + src/conf/node_device_conf.c | 5 + src/conf/node_device_conf.h | 1 + src/conf/schemas/basictypes.rng | 31 ++++ src/conf/schemas/domaincommon.rng | 41 +---- src/conf/schemas/nodedev.rng | 3 + src/hypervisor/virhostdev.c | 131 ++++++++------ src/libvirt_private.syms | 2 - src/node_device/node_device_udev.c | 4 + src/util/virusb.c | 160 ++++++------------ src/util/virusb.h | 22 +-- .../usb_device_1d6b_1_0000_00_1d_0.xml | 1 + ...ostdev-usb-address-port.x86_64-latest.args | 36 ++++ ...hostdev-usb-address-port.x86_64-latest.xml | 45 +++++ .../hostdev-usb-address-port.xml | 28 +++ ...tdev-usb-vendor-product.x86_64-latest.args | 35 ++++ ...stdev-usb-vendor-product.x86_64-latest.xml | 44 +++++ .../hostdev-usb-vendor-product.xml | 36 ++++ tests/qemuxmlconftest.c | 25 +++ tests/virusbtest.c | 149 +++++++++++----- .../sys_bus_usb/devices/1-1.5.3.1/devpath | 1 + .../sys_bus_usb/devices/1-1.5.3.3/devpath | 1 + .../sys_bus_usb/devices/1-1.5.3/devpath | 1 + .../sys_bus_usb/devices/1-1.5.4/devpath | 1 + .../sys_bus_usb/devices/1-1.5.5/devpath | 1 + .../sys_bus_usb/devices/1-1.5.6/devpath | 1 + .../sys_bus_usb/devices/1-1.5/devpath | 1 + .../sys_bus_usb/devices/1-1.6/devpath | 1 + .../sys_bus_usb/devices/1-1/devpath | 1 + .../sys_bus_usb/devices/2-1.2/devpath | 1 + .../sys_bus_usb/devices/2-1/devpath | 1 + .../sys_bus_usb/devices/usb1/devpath | 1 + .../sys_bus_usb/devices/usb2/devpath | 1 + .../sys_bus_usb/devices/usb3/devpath | 1 + .../sys_bus_usb/devices/usb4/devpath | 1 + 37 files changed, 631 insertions(+), 271 deletions(-) create mode 100644 tests/qemuxmlconfdata/hostdev-usb-address-port.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/hostdev-usb-address-port.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/hostdev-usb-address-port.xml create mode 100644 tests/qemuxmlconfdata/hostdev-usb-vendor-product.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/hostdev-usb-vendor-product.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/hostdev-usb-vendor-product.xml create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.3.1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.3.3/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.3/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.4/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.5/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.6/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.6/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/2-1.2/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/2-1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb2/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb3/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb4/devpath -- 2.39.5

[RFC PATCH v4 0/5] Added virtio-net RSS with eBPF support.
by Andrew Melnychenko 14 Oct '25

14 Oct '25

This series of rfc patches adds support for loading the RSS eBPF program and passing it to the QEMU. Comments and suggestions would be useful. QEMU with vhost may work with RSS through eBPF. To load eBPF, the capabilities required that Libvirt may provide. eBPF program and maps may be unique for particular QEMU and Libvirt retrieves eBPF through qapi. For now, there is only "RSS" eBPF object in QEMU, in the future, there may be another one(g.e. network filters). That's why in Libvirt added logic to load and store any eBPF object that QEMU provides using qapi schema. One of the reasons why this series of patches is in RFC are tests. To this series of patches, the tests were added. For now, the tests are synthetic, the proper "reply" file should be generated with a new "caps" file. Currently, there are changes in caps-9.0.0* and caps-9.1.0 files. There was added support for ebpf_rss_fds feature, and request-ebpf command. So, overall, the tests are required for review, comment, and discussion how we want them to be implemented in the future. For virtio-net RSS, the document has not changed. ``` <interface type="network"> <model type="virtio"/> <driver queues="4" rss="on" rss_hash_report="off"/> <interface type="network"> ``` Simplified routine for RSS: * Libvirt retrieves eBPF "RSS" and load it. * Libvirt passes file descriptors to virtio-net with property "ebpf_rss_fds" ("rss" property should be "on" too). * if fds was provided - QEMU using eBPF RSS implementation. * if fds was not provided - QEMU tries to load eBPF RSS in own context and use it. * if eBPF RSS was not loaded - QEMU uses "in-qemu" RSS(vhost not supported). Changes since RFC v3: * changed tests a bit * refactored and rebased * removed "allowEBPF" from qemu config(now env is used for tests) Changes since RFC v2: * refactored and rebased. * applied changes according to the Qemu. * added basic test. Changes since RFC v1: * changed eBPF format saved in the XML cache. * refactored and checked with syntax test. * refactored patch hunks. Andrew Melnychenko (5): qemu_monitor: Added QEMU's "request-ebpf" support. qemu_capabilities: Added logic for retrieving eBPF objects from QEMU. qemu_interface: Added routine for loading the eBPF objects. qemu_command: Added "ebpf_rss_fds" support for virtio-net. tests: Added tests for eBPF blob loading. libvirt.spec.in | 3 + meson.build | 7 + meson_options.txt | 1 + src/qemu/meson.build | 1 + src/qemu/qemu_capabilities.c | 132 ++++++++++++ src/qemu/qemu_capabilities.h | 5 + src/qemu/qemu_command.c | 60 ++++++ src/qemu/qemu_domain.c | 4 + src/qemu/qemu_domain.h | 3 + src/qemu/qemu_interface.c | 87 ++++++++ src/qemu/qemu_interface.h | 7 + src/qemu/qemu_monitor.c | 9 + src/qemu/qemu_monitor.h | 4 + src/qemu/qemu_monitor_json.c | 27 +++ src/qemu/qemu_monitor_json.h | 4 + .../caps_9.0.0_sparc.replies | 95 +++++---- .../qemucapabilitiesdata/caps_9.0.0_sparc.xml | 3 + .../caps_9.0.0_x86_64.replies | 199 ++++++++++-------- .../caps_9.0.0_x86_64.xml | 4 + .../caps_9.1.0_x86_64.replies | 199 ++++++++++-------- .../caps_9.1.0_x86_64.xml | 4 + tests/qemuxml2argvmock.c | 24 +++ .../net-virtio-rss-bpf.x86_64-latest.args | 37 ++++ .../net-virtio-rss-bpf.x86_64-latest.xml | 46 ++++ tests/qemuxmlconfdata/net-virtio-rss-bpf.xml | 46 ++++ tests/qemuxmlconftest.c | 5 + 26 files changed, 792 insertions(+), 224 deletions(-) create mode 100644 tests/qemuxmlconfdata/net-virtio-rss-bpf.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/net-virtio-rss-bpf.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/net-virtio-rss-bpf.xml -- 2.45.2

[PATCH 00/31] qemu: Improve handling of architecture-specific defaults (USB and PCI)
by Andrea Bolognani 19 Sep '25

19 Sep '25

Just like the series dealing with [SCSI] from last month, this is an effort to complete work that I had started in early 2024 ([v2], [v1]) and then promptly forgot about. Dealing with USB controllers is a lot easier compared to a year and a half ago because Peter has already brought some much-needed sanity to their handling in the meantime, including finally removing all uses of -usb, but there's still room for improvement. Looking at USB controllers made me realize that we were doing things incorrectly or suboptimally on the PCI side as well, so there are a number of changes in that part of libvirt too. Since USB controllers are PCI devices, some of the changes in one area directly affect the other one and it would have been challening to separate these patches into two smaller series in a way that would make sense, so unfortunately you get a single big one instead. Sorry.

[PATCH v2 00/10] qemu: Fixes to firmware selection
by Andrea Bolognani 10 Sep '25

[PATCH 0/3] A couple improvements when auto-adding PCI controllers
by Laine Stump 08 Sep '25

08 Sep '25

The 1st patch fixes a tiny omission from a feature added several years ago, which slightly improves the error message when you attempt to add a pcie-to-pci-bridge controller to a domain that has no PCIe bus. The 2nd improves that error message a bit more, along with improving some comments in the code. The 3rd eliminates said error message completely when you're adding a pcie-to-pci-bridge controller to a domain that *does* support PCIe, but doesn't currently have an open pcie-root-port to plug in the pcie-to-pci-bridge (by auto-adding another pcie-root-port). The impetus for these was https://issues.redhat.com/browse/RHEL-62032 Laine Stump (3): conf: add forgotten clause to virDomainPCIControllerConectTypeToModel() conf: improve error message when a PCI controller can't be auto-added conf: auto-add a pcie-root-port when needed while plugging in pcie-to-pci-bridge src/conf/domain_addr.c | 43 +++++++++++++++---- .../pcie-root-port-too-many.x86_64-latest.err | 2 +- 2 files changed, 35 insertions(+), 10 deletions(-) -- 2.51.0

[PATCH v5 0/6] qemu: acpi-generic-initiator support
by Andrea Righi 06 Sep '25

06 Sep '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> <pci-dev>hostdev0</pci-dev> <numa-node>1</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <pci-dev>hostdev0</pci-dev> <numa-node>2</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <pci-dev>hostdev0</pci-dev> <numa-node>3</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <pci-dev>hostdev0</pci-dev> <numa-node>4</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <pci-dev>hostdev0</pci-dev> <numa-node>5</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <pci-dev>hostdev0</pci-dev> <numa-node>6</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <pci-dev>hostdev0</pci-dev> <numa-node>7</numa-node> </acpi-generic-initiator> <acpi-generic-initiator> <pci-dev>hostdev0</pci-dev> <numa-node>8</numa-node> </acpi-generic-initiator> </devices> ``` -
