[ 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 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.

[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

[PATCHv2] passt: Define backend hostname and fqdn
by Enrique Llorente 03 Sep '25

03 Sep '25

This commit introduces a feature enhancement for configuring hostnames in virtual machines (VMs) using DHCP. It adds new options to the "passt" tool to set the hostname and fully qualified domain name (FQDN) for VMs. These map to DHCP option 12 for the hostname and options 81 (IPv4) and 39 (IPv6) for the FQDN. The update enables passt to dynamically assign hostnames to DHCP-aware VMs. To achieve this, the commit adds two fields to the passt domain XML backend. These fields allow passt to configure the hostname and FQDN for the virtual machine, ensuring smooth integration with the DHCP protocol. This improvement is particularly valuable in environments where VMs need dynamic hostname configuration, enhancing flexibility and automation in virtualized network setups. libvirt: Integrate passt --hostname --fqdn options Resolves: https://issues.redhat.com/browse/RHEL-79806 Signed-off-by: Enrique Llorente <ellorent(a)redhat.com> --- Compared to v1 this fix the mapping between backend fqdn and hostname docs/formatdomain.rst | 8 +++++--- src/conf/domain_conf.c | 10 +++++++++- src/conf/domain_conf.h | 2 ++ src/conf/schemas/domaincommon.rng | 6 ++++++ src/qemu/qemu_passt.c | 6 ++++++ tests/qemuxmlconfdata/net-user-passt.x86_64-7.2.0.xml | 2 +- tests/qemuxmlconfdata/net-user-passt.x86_64-latest.xml | 2 +- tests/qemuxmlconfdata/net-user-passt.xml | 2 +- .../net-vhostuser-passt.x86_64-latest.xml | 2 +- tests/qemuxmlconfdata/net-vhostuser-passt.xml | 2 +- 10 files changed, 33 insertions(+), 9 deletions(-) diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index 8753ee9c23..9c80aa9270 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -5372,10 +5372,12 @@ came from the host's IP.

[PATCH v2 00/11] Enabling logging for ch guests
by Praveen K Paladugu 18 Aug '25

18 Aug '25

LogContext management is now moved from Qemu driver to hypervisor. After migrating Qemu to use domain_logcontext, I extended ch driver to use also use domain_logcontext to capture early boot failures within domain specific log files. Changes in V2: * refactored the patches to ensure all of them build. * ch driver will use virtlogd to consolidate logs from hypervisor and its domains.

[PATCH v2 0/4] bhyve: implement domain{Block,Interface,Memory}Stats
by Roman Bogorodskiy 18 Aug '25

18 Aug '25

Changes since v1: - Added "bhyve: implement domainInterfaceStats" patch PS It was temping to factor out obtaining struct kinfo_proc using sysctlnametomib() + sysctl(), but I have to make it visible to use outside of virprocess, e.g. in bhyve_driver.c, so it doesn't look like it's worth the effort for now. Probably it'll make sense to implement a FreeBSD version of virProcessGetStat() once there are more users of this code.
