Plans for 12.0.0 release (freeze on 2026-01-09)
by Jiri Denemark 05 Jan '26

05 Jan '26

We are getting close to 12.0.0 release of libvirt. To aim for the release on Thursday 15 Jan I suggest entering the freeze on Friday 09 Jan and tagging RC2 on Tuesday 13 Jan. I hope this works for everyone. Jirka

[PATCH] bhyve: rework capabilities probing
by Roman Bogorodskiy 02 Jan '26

02 Jan '26

Currently, to probe PCI devices, for each device libvirt calls "bhyve -s 0,<device_type>" and parses the error message to check if this specific device is supported. For quite some time, bhyve reports the list of devices using: bhyve -s help where it prints all supported devices, one device per line. Update the code to use this command: * It is more accurate as we don't need to rely on the error message parsing. * It's faster as we get all the devices in one run instead of running bhyve for every device type. * The code is simpler.

[PATCH] tests: Remove temporary TZ parsing workaround
by Martin Kletzander 02 Jan '26

02 Jan '26

From: Martin Kletzander <mkletzan(a)redhat.com> This partially reverts commit 3caa28dc50df which changed the DST times to start at Jan 2 due to an issue that is already solved in GLib that we require for almost a year now. This also fixes the test failures that would go away on Jan 2 11:00 UTC (less than two hours from writing this commit message) due to the timezone definitions (the last failing test case has a timezone which is UTC+11:00), but because of the change from '0/' to '1/' it did occur on a day which is not caught by isNearYearEnd() which exists solely for this purpose.

[ 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 v5 00/28] hw/i386/pc: Remove deprecated 2.6 and 2.7 PC machines
by Zhao Liu 19 Dec '25

19 Dec '25

Hi, A brief introduction from Philippe's v4: The versioned 'pc' and 'q35' machines up to 2.12 been marked as deprecated three releases ago, and are older than 6 years, so according to our support policy we can remove them. This series only includes the 2.6 and 2.7 machines removal, as it is a big enough number of LoC removed. Rest will follow. This v5 is based on the master branch at the commit 66ec38b6fa59 ("Merge tag 'pull-target-arm-20251201' of https://gitlab.com/pm215/qemu into staging"). (Main) changes since v4: * Completely remove the legacy CPU hotplug approach. - New patch 2-8. - Test CPU hot-plug & hot-unplug via qmp. * Keep "dma_enabled" property in fw_cfg_io_properties[] since Sun4u & Sun4v are still using it. - About more details, please see commit message of patch 15. * Temporarily keep these properties: "cpuid-0xb" (of X86CPU), "fill-mtrr-mask" (of X86CPU), "version" (of IOAPICCommonState). - These properties will be deprecated first before removal, in another series. * Keep "l3-cache" (of X86CPU) and "page-per-vq" (of VirtIOPCIProxy), since they are still in use (e.g., libvirt). Thank you everyone for the reviews and patience, and also thank you Philippe for the guidance and Igor for the patch.
