[ 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

[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

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.

[PATCH rfcv4 00/13] LIBVIRT: X86: TDX support
by Zhenzhong Duan 02 Apr '25

02 Apr '25

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. To support TDX, multiple software components, not only KVM but also QEMU, guest Linux and virtual bios, need to be updated. For more details, please check link[1]. This patchset is another software component to extend 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 [2], matching qemu code can be found at [3]. There is a 'debug' property for tdx-guest object which isn't in matching qemu[3] yet. I keep them intentionally as they will be implemented in qemu as extention series of [3]. * Test start/stop/reboot with virsh stop/reboot trigger in guest stop with on_poweroff=destroy/restart reboot with on_reboot=destroy/restart * Patch organization - patch 1-4: Support query of TDX capabilities. - patch 5-8: Add TDX type to launchsecurity framework. - patch 9-11: Add reboot support to TDX guest - patch 12-13: Add test and docs TODO: - update QEMU capabilities data in tests, depending on qemu TDX merged beforehand - add reconnect logic in virsh command [1] https://lore.kernel.org/kvm/cover.1708933498.git.isaku.yamahata@intel.com [2] https://github.com/intel/libvirt-tdx/commits/tdx_for_upstream_rfcv4 [3] https://github.com/intel/qemu-tdx/tree/tdx-qemu-upstream-v5 Thanks Zhenzhong Changelog: rfcv4: - add a check to tools/virt-host-validate-qemu.c (Daniel) - remove check of q35 (Daniel) - model 'SocktetAddress' QAPI in xml schema (Daniel) - s/Quote-Generation-Service/quoteGenerationService/ (Daniel) - define bits in tdx->policy and add validating logic (Daniel) - presume QEMU choose split kernel irqchip for TDX guest by default (Daniel) - utilize existing FakeReboot framework to do reboot for TDX guest (Daniel) - drop patch11 'conf: Add support to keep same domid for hard reboot' (Daniel) - add test in tests/ to validate parsing and formatting logic (Daniel) - add doc in docs/formatdomain.rst (Daniel) - add R-B rfcv3: - Change to generate qemu cmdline with -bios - drop firmware auto match as -bios is used - add a hard reboot method to reboot TDX guest rfcv3: https://www.mail-archive.com/devel@lists.libvirt.org/msg00385.html rfcv2: - give up using qmp cmd and check TDX directly on host for TDX capabilities. - use launchsecurity framework to support TDX - use <os>.<loader> for general loader - add auto firmware match feature for TDX A example TDVF fimware description file 70-edk2-x86_64-tdx.json: { "description": "UEFI firmware for x86_64, supporting Intel TDX", "interface-types": [ "uefi" ], "mapping": { "device": "generic", "filename": "/usr/share/OVMF/OVMF_CODE-tdx.fd" }, "targets": [ { "architecture": "x86_64", "machines": [ "pc-q35-*" ] } ], "features": [ "intel-tdx", "verbose-dynamic" ], "tags": [ ] } rfcv2: https://www.mail-archive.com/libvir-list@redhat.com/msg219378.html Zhenzhong Duan (13): tools: Secure guest check for Intel in virt-host-validate qemu: Check if INTEL Trust Domain Extention support is enabled qemu: Add TDX capability conf: expose TDX feature in domain capabilities conf: add tdx as launch security type qemu: Add command line and validation for TDX type qemu: force special parameters enabled for TDX guest Add Intel TDX Quote Generation Service(QGS) support qemu: add FakeReboot support for TDX guest qemu: Support reboot command in guest qemu: Avoid duplicate FakeReboot for secure guest Add test cases for Intel TDX docs: domain: Add documentation for Intel TDX guest docs/formatdomain.rst | 68 ++++ docs/formatdomaincaps.rst | 1 + src/conf/domain_capabilities.c | 1 + src/conf/domain_capabilities.h | 1 + src/conf/domain_conf.c | 312 ++++++++++++++++++ src/conf/domain_conf.h | 75 +++++ src/conf/schemas/domaincaps.rng | 9 + src/conf/schemas/domaincommon.rng | 135 ++++++++ src/conf/virconftypes.h | 2 + src/qemu/qemu_capabilities.c | 36 +- src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 139 ++++++++ src/qemu/qemu_firmware.c | 1 + src/qemu/qemu_monitor.c | 28 +- src/qemu/qemu_monitor.h | 2 +- src/qemu/qemu_monitor_json.c | 6 +- src/qemu/qemu_namespace.c | 1 + src/qemu/qemu_process.c | 75 +++++ src/qemu/qemu_validate.c | 44 +++ ...unch-security-tdx-qgs-fd.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-fd.xml | 30 ++ ...ch-security-tdx-qgs-inet.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-inet.xml | 30 ++ ...ch-security-tdx-qgs-unix.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-unix.xml | 30 ++ ...h-security-tdx-qgs-vsock.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-vsock.xml | 30 ++ tests/qemuxmlconftest.c | 24 ++ tools/virt-host-validate-common.c | 22 +- tools/virt-host-validate-common.h | 1 + 30 files changed, 1407 insertions(+), 5 deletions(-) create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-fd.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-fd.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-inet.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-inet.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-unix.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-unix.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-vsock.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-vsock.xml -- 2.34.1

[PATCH 00/26] integrate auto-shutdown of VMs with daemons
by Daniel P. Berrangé 11 Mar '25

11 Mar '25

This series starts the work needed to obsolete the libvirt-guests.sh script which has grown a surprisingly large amount of functionality. Currently the virt daemons will acquire inhibitors to delay OS shutdown when VMs are running. The libvirt-guests.service unit can be used to call libvirt-guests.sh to shutdown running VMs on system shutdown. This split is a bad architecture because libvirt-guests.service will only run once the system has decided to initiate the shutdown sequence. When the user requests as shutdown while inhibitors are present, logind will emit a "PrepareForShutdown" signal over dbus. Applications are supposed to respond to this by preserving state & releasing their inhibitors, which in turns allows shutdown to be initiated. The remote daemon already has support for listening for the "PrepareForShutdown" signal, but only does this for session instances, not system instances. This series essentially takes that logic and expands it to run in the system instances too, thus conceptually making libvirt-guests.service obsolete. It is slightly more complicated than that though for many reasons... Saving running VMs can take a very long time. The inhibitor delay can be as low as 5 seconds, and when killing a service, systemd may not wait very long for it to terminate. libvirt-guests.service deals with this by setting TimeoutStopSecs=0 to make systemd wait forever. This is undesirable to set in libvirtd.service though, as we would like systemd to kill the daemon aggressively if it hangs. The series thus uses the notification protocol to request systemd give it more time to shutdown, as long as we're in the phase of saving running VMs. A bug in this code will still result in systemd waiting forever, which is no different from libvirt-guests.service, but a bug in any other part of the libvirt daemon shutdown code will result in systemd killing us. The existing logic for saving VMs in the session daemons had many feature gaps compared to libvirt-guests.sh. Thus there is code to add support * Requesting graceful OS shutdown if managed save failed * Force poweroff of VMs if no other action worked * Optionally enabling/disabling use of managed save, graceful shutdown and force poweroff, which is more flexible than ON_SHUTDOWN=nnn, as we can try the whole sequence of options * Ability to bypass cache in managed save * Support for one-time autostart of VMs as an official API To aid in testing this logic, virt-admin gains a new command 'virt-admin daemon-shutdown --preserve' All this new functionality is wired up into the QEMU driver, and is made easily accessible to other hypervisor drivers, so would easily be extendable to Xen, CH, LXC drivers, but this is not done in this series. IOW, libvirt-guests.service is not yet fully obsolete. The new functionality is also not enabled by default for the system daemon, it requires explicit admin changes to /etc/libvirt/qemu.conf to enable it. This is because it would clash with execution of the libvirt-guests.service if both were enabled. It is highly desirable that we enable this by default though, so we need to figure out a upgrade story wrt libvirt-guests.service. The only libvirt-guests.sh features not implemented are: * PARALLEL_SHUTDOWN=nn. When doing a graceful shutdown we initiate it on every single VM at once, and then monitor progress of all of them in parallel. * SYNC_TIME=nn When make not attempt to sync guest time when restoring from managed save. This ought to be fixed Daniel P. Berrangé (26): util: add APIs for more systemd notifications remote: notify systemd when reloading config hypervisor: introduce helper for autostart src: convert drivers over to use new autostart helper hypervisor: add support for delay interval during autostart qemu: add 'auto_start_delay' configuration parameter hypervisor: move support for auto-shutdown out of QEMU driver remote: always invoke virStateStop for all daemons hypervisor: expand available shutdown actions hypervisor: custom shutdown actions for transient vs persistent VMs qemu: support automatic VM managed save in system daemon qemu: improve shutdown defaults for session daemon qemu: configurable delay for shutdown before poweroff hypervisor: support bypassing cache for managed save qemu: add config parameter to control auto-save bypass cache src: add new APIs for marking a domain to autostart once conf: implement support for autostart once feature hypervisor: wire up support for auto restore of running domains qemu: wire up support for once only autostart qemu: add config to control if auto-shutdown VMs are restored rpc: move state stop into virNetDaemon class rpc: don't unconditionally quit after preserving state rpc: fix shutdown sequence when preserving state admin: add 'daemon-shutdown' command rpc: don't let systemd shutdown daemon while saving VMs hypervisor: send systemd status messages while saving include/libvirt/libvirt-admin.h | 13 ++ include/libvirt/libvirt-domain.h | 4 + src/admin/admin_protocol.x | 11 +- src/admin/admin_server_dispatch.c | 13 ++ src/admin/libvirt-admin.c | 33 ++++ src/admin/libvirt_admin_public.syms | 5 + src/bhyve/bhyve_driver.c | 53 ++---- src/conf/domain_conf.c | 6 +- src/conf/domain_conf.h | 1 + src/conf/virdomainobjlist.c | 7 +- src/driver-hypervisor.h | 10 ++ src/hypervisor/domain_driver.c | 250 ++++++++++++++++++++++++++++ src/hypervisor/domain_driver.h | 42 +++++ src/libvirt-domain.c | 87 ++++++++++ src/libvirt_private.syms | 10 +- src/libvirt_public.syms | 6 + src/libvirt_remote.syms | 2 +- src/libxl/libxl_driver.c | 36 ++-- src/lxc/lxc_driver.c | 13 +- src/lxc/lxc_process.c | 18 +- src/lxc/lxc_process.h | 2 + src/qemu/libvirtd_qemu.aug | 7 + src/qemu/qemu.conf.in | 59 +++++++ src/qemu/qemu_conf.c | 63 +++++++ src/qemu/qemu_conf.h | 7 + src/qemu/qemu_driver.c | 203 +++++++++++++--------- src/qemu/test_libvirtd_qemu.aug.in | 7 + src/remote/libvirtd.service.in | 2 +- src/remote/remote_daemon.c | 78 +++------ src/remote/remote_driver.c | 2 + src/remote/remote_protocol.x | 30 +++- src/remote_protocol-structs | 12 ++ src/rpc/gendispatch.pl | 4 +- src/rpc/virnetdaemon.c | 212 +++++++++++++++++++---- src/rpc/virnetdaemon.h | 20 ++- src/util/virsystemd.c | 41 ++++- src/util/virsystemd.h | 6 +- src/virtd.service.in | 2 +- tools/virsh-domain-monitor.c | 5 + tools/virsh-domain.c | 39 ++++- tools/virt-admin.c | 41 +++++ 41 files changed, 1181 insertions(+), 281 deletions(-) -- 2.47.1

[PATCH 0/4] hw/s390x: Alias @dump-skeys -> @dump-s390-skey and deprecate
by Philippe Mathieu-Daudé 10 Mar '25

10 Mar '25

We are trying to unify all qemu-system-FOO to a single binary. In order to do that we need to remove QAPI target specific code. @dump-skeys is only available on qemu-system-s390x. This series rename it as @dump-s390-skey, making it available on other binaries. We take care of backward compatibility via deprecation.
