[PATCH v4 00/23] LIBVIRT: X86: TDX support
by Zhenzhong Duan 07 Jan '26

07 Jan '26

Hi, This series brings libvirt the x86 TDX support. * What's TDX? TDX stands for Trust Domain Extensions which isolates VMs from the virtual-machine manager (VMM)/hypervisor and any other software on the platform. This patchset extends libvirt to support TDX, with which one can start a TDX guest from high level rather than running qemu directly. * Misc As QEMU use a software emulated way to reset guest which isn't supported by TDX guest for security reason. We simulate reboot for TDX guest by kill and create a new one in FakeReboot framework. Complete code can be found at [1]. * Test Tested with upstream qemu v10.0.0-1724-gf9a3def17b shutdown/reboot/reset with virsh shutdown/reboot trigger in guest shutdown with on_poweroff=destroy/restart reboot with on_reboot=destroy/restart GUEST_PANICKED event processing auto firmware matching * Patch organization -

[ PATCH vf-token 0/8] Introduce vf-token when using userspace PF
by Vivek Kashyap 23 Dec '25

23 Dec '25

The VFIO PCI ABI has been extended to require userspace PF driver to set a VF token to a known value. The VF drivers are then required to provide this token to access the VF device. The vf-token is set by the PF driver before VF drivers can access the device. The kernel provides no means to retrieve the token in use; but there is no specification describing the distribution or level of confidentiality of the token. Qemu has been extended to require the vf-token when vf device is used. An important point to note is that the vf-token is required only when both the PF and VF are used in userspace. This patch series adds support to provide the vf-token (uuid format) in the domain XML and to generate the qemu commandline including the vf-token. To support vf-token the new element will be used as follows: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x0' slot='0x00' function='0x1'> <vf-token uuid='00112233-4455-6677-8899-aabbccddeeff'/> </address> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/> </hostdev> The generated commandline will include the following: -device {"driver":"vfio-pci","host":"0000:00:0.1", "vf-token":"00112233-4455-6677-8899-aabbccddeeff", "id":"hostdev0","bus":"pci.0","addr":"0x1"} Changes since initial RFC based on review comments received: 1. Added documentation 2. Added test cases and ran successful test suite after each patch commit 3. fixed spaces, coding sytle, and uuid string format 4. Used S:vftoken in virJSONValueObjectAdd instead of a conditional Vivek Kashyap (8): Define the vf-token extension for PCI device Introduce the vf-token qemu capability This patch introduces the PCI address extension flag for vf-token This patch introduces new XML parser/formatter functions for parsing the vf-token Introduce a validation function for vf-token support in qemu and generate vf-token device attribute in qemu command line Provide information about the vf-token flag Add tests for the vf-token flag to the qemuxml2argv and qemuxml2xml test suites Update news about vf-token NEWS.rst | 8 +++ docs/formatdomain.rst | 3 ++ src/conf/device_conf.c | 49 ++++++++++++++++--- src/conf/domain_addr.h | 1 + src/conf/domain_conf.c | 8 +++ src/conf/schemas/basictypes.rng | 7 +++ src/libvirt_private.syms | 1 + src/qemu/qemu_capabilities.c | 3 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 8 +++ src/qemu/qemu_domain_address.c | 3 ++ src/qemu/qemu_validate.c | 20 ++++++++ src/util/virpci.c | 7 +++ src/util/virpci.h | 10 ++++ .../qemucapabilitiesdata/caps_8.1.0_s390x.xml | 1 + .../caps_8.1.0_x86_64.xml | 1 + .../caps_8.2.0_x86_64.xml | 1 + .../hostdev-vfio-vf-token.x86_64-latest.args | 34 +++++++++++++ .../hostdev-vfio-vf-token.xml | 22 +++++++++ tests/qemuxml2argvtest.c | 1 + .../hostdev-vfio-vf-token.x86_64-latest.xml | 40 +++++++++++++++ tests/qemuxml2xmltest.c | 1 + 22 files changed, 223 insertions(+), 7 deletions(-) create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-vf-token.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/hostdev-vfio-vf-token.xml create mode 100644 tests/qemuxml2xmloutdata/hostdev-vfio-vf-token.x86_64-latest.xml -- 2.33.8

[PATCH v3 0/7] USB hostdev: allow addressing by port
by Maximilian Martin 20 Nov '25

20 Nov '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.

[PATCH 0/1] cpu_map: fix vmx-* features wrong bitmaps
by Hector Cao 12 Nov '25

12 Nov '25

Hello, I'm unable to make virsh capabilities to detect the right CPU model on an Intel Granite Rapids platform. I would expect the get the CPU model defined in one of the src/cpu_map/x86_GraniteRapids*.xml files. The cause of the wrong detection is the fact that some vmx-* are not correctly detected and considered missing on this platform. When I take a look at the src/cpu_map/x86_features.xml file, I think that some of the vmx-* are wrongly defined. Taking as an example the vmx-apicv-xapic feature, it is defined as the first bit in the EAX register when we read the MSR 0x0000048b . But in Intel specification, this feature is represented as the first bit in the EDX register (32 higher bits). You can find in this submission the patch that fixes this issue, and this for all the affected MSRs. I tested this fix on my Granite Rapids platform and the CPU model is now correctly detected.

[PATCH v3 0/8] Enable mshv support for Qemu domains
by Praveen K Paladugu 18 Oct '25

18 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.

[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 20 Sep '25

20 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
