[PATCH v2 0/2] Fix sanlock without qemu (dejavu)
by Daniel P. Berrangé 06 Oct '25

06 Oct '25

My previous RPM fix was wrong, as sanlock can actually be used with libxl too. It is the meson rules that were wrong. Daniel P.

[PATCH v2 00/38] qemu: Improve handling of architecture-specific defaults (USB and PCI)
by Andrea Bolognani 06 Oct '25

06 Oct '25

Changes from [v1]: * overhaul/fix validation of USB controllers. Previously the check was based around whether the controller had a PCI address assigned to it, but that was incorrect and insufficient. The new check is based on the controller model instead; * split functional changes in the last stretch of the series into smaller chunks and justify each one separately; * avoid use of nec-xhci for RISC-V and LoongArch; * add test suite coverage and special handling for microvm; * address other review comments. [v1] https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/D7VF… Andrea Bolognani (38): tests: Fix typo in usb-controller-nec-xhci-autoassign tests: Drop coverage for versatilepb on aarch64 tests: Don't use memballoon=none for minimal tests tests: Don't set PCI address in usb-controller-default tests tests: Minimize usb-controller tests tests: Rename usb-controller-implicit-* tests: Expand coverage for automatic/default USB controllers tests: Fix some usb-controller-*-unavailable cases qemu: Check for pci-ohci availability tests: Use realview-eb instead of realview-pbx-a9 qemu: Fix PCI/USB handling for Arm realview boards tests: Add coverage for PCI use with isapc and microvm qemu: Don't add memballoon to isapc qemu: Don't add PCI, USB or memballoon to microvm qemu: Introduce qemuDomainNetIsPCI() qemu: Prevent use of PCI devices when PCI is not supported qemu: Validate presence of PCI support qemu: Update qemuDomainSupportsPCI() qemu: Add sanity checks for auto-added PCI and USB controllers qemu: Always default to no USB controller on s390x qemu: Don't generate alias for model=none USB controllers qemu: Drop skip for USB controllers on s390x qemu: Fold check into qemuBuildSkipController() qemu: Rename function argument qemu: Validate PCI support for USB controllers qemu: Skip USB controller validation when model=none qemu: Validate USB controllers earlier qemu: Add qemuDomainDefaultUSBControllerModel() qemu: Add qemuDomainDefaultUSBControllerModelAutoAdded() qemu: Clean up qemuDomainDefaultUSBControllerModel() qemu: Clean up qemuDomainDefaultUSBControllerModelAutoAdded() qemu: Use qemu-xhci with no fallback on loongarch64 qemu: Use qemu-xhci with no fallback on RISC-V qemu: Unify USB controllers across Arm architectures qemu: Don't special-case realview/versatilebp for USB qemu: Remove fallback to piix3-uhci for Arm virt guests qemu: Remove use of piix3-uhci for non-x86 news: Update for USB controller model selection

[PATCH] src: report error from failing to add timer/FD watches
by Daniel P. Berrangé 03 Oct '25

03 Oct '25

From: Daniel P. Berrangé <berrange(a)redhat.com> The virEventAddHandle/Timeout APIs are unusual in that they do not report errors on failure, because they call through to function callbacks which might be provided externally to libvirt and thus won't be using libvirt's error reporting APIs. This is a rather unfortunate design characteristic as we can see most callers forgot about this special behaviour and so we are lacking error reporting in many cases. Signed-off-by: Daniel P.

[RFC PATCH v5 0/7] qemu: Implement support for iommufd and multiple HW-accel vSMMUs
by Nathan Chen 02 Oct '25

02 Oct '25

Hi, This is a follow up to the fourth RFC patchset [0] for supporting multiple vSMMU instances and using iommufd to propagate DMA mappings to kernel for VM-assigned host devices in a qemu VM. This patchset implements support for specifying multiple <iommu> devices within the VM definition when smmuv3Dev IOMMU model is specified, and is tested with Shameer's v4 qemu RFC for HW-accelerated vSMMU devices [1] Moreover, it adds a new 'iommufd' attribute for hostdev devices to be associated with the iommufd object. For instance, specifying the iommufd object and associated hostdev in a VM definition with multiple IOMMUs, configured to be routed to pcie-expander-bus controllers in a way where VFIO device to SMMUv3 associations are matched with the host: <devices> ... <controller type='pci' index='1' model='pcie-expander-bus'> <model name='pxb-pcie'/> <target busNr='252'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/> </controller> <controller type='pci' index='2' model='pcie-expander-bus'> <model name='pxb-pcie'/> <target busNr='248'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </controller> ... <controller type='pci' index='21' model='pcie-root-port'> <model name='pcie-root-port'/> <target chassis='21' port='0x0'/> <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </controller> <controller type='pci' index='22' model='pcie-root-port'> <model name='pcie-root-port'/> <target chassis='22' port='0xa8'/> <address type='pci' domain='0x0000' bus='0x02' slot='0x00' function='0x0'/> </controller> ... <hostdev mode='subsystem' type='pci' managed='no'> <driver iommufd='yes'/> <source> <address domain='0x0009' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x15' slot='0x00' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='no'> <driver iommufd='yes'/> <source> <address domain='0x0019' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x16' slot='0x00' function='0x0'/> </hostdev> <iommu model='smmuv3Dev'> <driver parentIdx='1' accel='on' ats='on' ril='on' pasid='on' oas='44'/> </iommu> <iommu model='smmuv3Dev'> <driver parentIdx='2' accel='on' ats='on' ril='on' pasid='on' oas='44'/> </iommu> </devices> This would get translated to a qemu command line with the arguments below. Note that libvirt will open the /dev/iommu and VFIO cdev, passing the associated fd number to qemu: -device '{"driver":"pxb-pcie","bus_nr":252,"id":"pci.1","bus":"pcie.0","addr":"0x1"}' \ -device '{"driver":"pxb-pcie","bus_nr":248,"id":"pci.2","bus":"pcie.0","addr":"0x2"}' \ -device '{"driver":"pcie-root-port","port":0,"chassis":21,"id":"pci.21","bus":"pci.1","addr":"0x0"}' \ -device '{"driver":"pcie-root-port","port":168,"chassis":22,"id":"pci.22","bus":"pci.2","addr":"0x0"}' \ -object '{"qom-type":"iommufd","id":"iommufd0","fd":"24"}' \ -device '{"driver":"arm-smmuv3","primary-bus":"pci.1","id":"smmuv3.0","accel":true,"ats":true,"ril":true,"pasid":true,"oas":44}' \ -device '{"driver":"arm-smmuv3","primary-bus":"pci.2","id":"smmuv3.1","accel":true,"ats":true,"ril":true,"pasid":true,"oas":44}' \ -device '{"driver":"vfio-pci","host":"0009:01:00.0","id":"hostdev0","iommufd":"iommufd0","fd":"22","bus":"pci.21","addr":"0x0"}' \ -device '{"driver":"vfio-pci","host":"0019:01:00.0","id":"hostdev1","iommufd":"iommufd0","fd":"25","bus":"pci.22","addr":"0x0"}' \ Changes from RFCv3: - Move smmuv3Dev-specific attributes under <driver> - Include new smmuv3Dev-specific attributes based on Shameer's v4 qemu series This series is on Github: https://github.com/NathanChenNVIDIA/libvirt/tree/smmuv3Dev-iommufd-10-01-25 Thanks, Nathan [0] https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/T66F… [1] https://lore.kernel.org/all/20250929133643.38961-1-skolothumtho@nvidia.com/… Signed-off-by: Nathan Chen <nathanc(a)nvidia.com> Nathan Chen (7): qemu: add IOMMU model smmuv3Dev conf: Support multiple smmuv3Dev IOMMU devices tests: qemuxmlconfdata: provide smmuv3Dev sample XML and CLI args qemu: Implement support for associating iommufd to hostdev qemu: open iommufd FDs from libvirt backend qemu: Update Cgroup, namespace, and seclabel for qemu to access iommufd paths tests: qemuxmlconfdata: provide iommufd sample XML and CLI args docs/formatdomain.rst | 44 ++- src/conf/device_conf.c | 9 + src/conf/device_conf.h | 1 + src/conf/domain_conf.c | 177 +++++++++-- src/conf/domain_conf.h | 16 +- src/conf/domain_validate.c | 73 ++++- src/conf/schemas/basictypes.rng | 5 + src/conf/schemas/domaincommon.rng | 35 ++- src/libvirt_private.syms | 2 + src/qemu/qemu_alias.c | 15 +- src/qemu/qemu_cgroup.c | 61 ++++ src/qemu/qemu_cgroup.h | 1 + src/qemu/qemu_command.c | 275 +++++++++++++----- src/qemu/qemu_command.h | 3 +- src/qemu/qemu_domain.c | 8 + src/qemu/qemu_domain.h | 7 + src/qemu/qemu_domain_address.c | 33 ++- src/qemu/qemu_driver.c | 8 +- src/qemu/qemu_hotplug.c | 2 +- src/qemu/qemu_namespace.c | 44 +++ src/qemu/qemu_postparse.c | 11 +- src/qemu/qemu_process.c | 232 +++++++++++++++ src/qemu/qemu_validate.c | 18 +- src/security/security_apparmor.c | 15 + src/security/security_dac.c | 34 +++ src/security/security_selinux.c | 30 ++ src/util/virpci.c | 68 +++++ src/util/virpci.h | 1 + .../iommu-smmuv3Dev.aarch64-latest.args | 39 +++ .../iommu-smmuv3Dev.aarch64-latest.xml | 66 +++++ tests/qemuxmlconfdata/iommu-smmuv3Dev.xml | 53 ++++ .../iommufd-q35.x86_64-latest.args | 41 +++ .../iommufd-q35.x86_64-latest.xml | 60 ++++ tests/qemuxmlconfdata/iommufd-q35.xml | 38 +++ .../iommufd-virt.aarch64-latest.args | 33 +++ .../iommufd-virt.aarch64-latest.xml | 34 +++ tests/qemuxmlconfdata/iommufd-virt.xml | 22 ++ .../iommufd.x86_64-latest.args | 35 +++ .../qemuxmlconfdata/iommufd.x86_64-latest.xml | 38 +++ tests/qemuxmlconfdata/iommufd.xml | 30 ++ tests/qemuxmlconftest.c | 5 + 41 files changed, 1584 insertions(+), 138 deletions(-) create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3Dev.aarch64-latest.args create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3Dev.aarch64-latest.xml create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3Dev.xml create mode 100644 tests/qemuxmlconfdata/iommufd-q35.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/iommufd-q35.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/iommufd-q35.xml create mode 100644 tests/qemuxmlconfdata/iommufd-virt.aarch64-latest.args create mode 100644 tests/qemuxmlconfdata/iommufd-virt.aarch64-latest.xml create mode 100644 tests/qemuxmlconfdata/iommufd-virt.xml create mode 100644 tests/qemuxmlconfdata/iommufd.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/iommufd.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/iommufd.xml -- 2.43.0

[PATCH] virt-login-shell: check for NULL from virGetLastError()
by gerben＠altlinux.org 01 Oct '25

01 Oct '25

From: Denis Rastyogin <gerben(a)altlinux.org> virGetLastError() may return NULL in case of OOM. Without a check this could lead to a NULL pointer dereference when accessing its fields. The result of virGetLastError() is usually checked in other places, so add the missing check here as well. Found by Linux Verification Center (linuxtesting.org) with SVACE.
