Or we need separate `blockcommit` step. Yes it is intended, because deleting a snapshot is effectively meaning "I don't want to return to this point any more" so the extra overlay makes no sense. > - Should the snapshot file be deleted automatically, or is manual cleanup required?

The semantics of external and internal snapshots are supposed to be indentical. I don't think we document to a deep extent the actual behaviour WRT to the disk files.

[PATCH v2] virhostcpu: Fix potential use of unallocated memory
by Felix Huettner 26 Mar '26

26 Mar '26

In case of a host that has a large number of cpus offline the count of host cpus and the last bit set in the virHostCPUGetOnlineBitmap might diverge significantly. This can e.g. be the case when disabling smt via /sys/devices/system/cpu/smt/control. On the host this looks like: ``` $ cat /sys/devices/system/cpu/present 0-255 $ cat /sys/devices/system/cpu/online 0-127 ``` However in this case virBitmapToData previously only allocated 16 bytes for the output bitmap. This is becase the last set bit is on the 15th byte. Users of virHostCPUGetMap however rely on the "cpumap" containing enough space for all existing cpus (so they would expect 32 bytes in this case). E.g. cmdNodeCpuMap relies on this for its output. It will then actually read 32 bytes from the start of the "cpumap" address where in this case the last 16 of these bytes are uninitialized. This manifests itself in flapping outputs of "virsh nodecpumap --pretty" like: ``` $ virsh nodecpumap --pretty CPUs present: 256 CPUs online: 128 CPU map: 0-127,192,194,202 $ virsh nodecpumap --pretty CPUs present: 256 CPUs online: 128 CPU map: 0-127,192,194,197 $ virsh nodecpumap --pretty CPUs present: 256 CPUs online: 128 CPU map: 0-127,192,194,196-197 ``` This in turn potentially causes users of this data to report wrong cpu counts. Note that this only seems to happen with at least 256 physical cpus where at least 128 are offline. We fix this by preallocating the expected bitmap size.

[PATCH v2 0/2] allow migrations with the ext transport
by Sergey Dyasli 19 Feb '26

19 Feb '26

Hello, I have a use case for live-migration where the socket of the destination libvirtd is proxied by an mTLS WebSocket proxy. Since there is no WebSocket support in Libvirt, I've decided to use the existing ext transport and point it to a proxy binary on the source host of live-migration. While doing that, I've discovered a couple of roadblocks: 1. There is no way of passing cmdline arguments to the ext program 2. Live-migrations using ext transport fail localhost checks This short series addresses those limitations.

[PATCH v3 0/7] USB hostdev: allow addressing by port
by Maximilian Martin 11 Feb '26

11 Feb '26

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. Maximilian Martin (7): tests: validate an XML config with USB vendor/product set virusb test data: add devpath files for port addressing domain_conf, virhostdev, virusb, virusb test: add bus/port matching schema: add USB port attribute tests: validate an XML config with USB bus/port set nodedev: add USB port to nodedev XML docs: add description for USB port matching docs/formatdomain.rst | 29 ++-- src/conf/domain_conf.c | 58 ++++++- src/conf/domain_conf.h | 1 + src/conf/node_device_conf.c | 5 + src/conf/node_device_conf.h | 1 + src/conf/schemas/basictypes.rng | 31 ++++ src/conf/schemas/domaincommon.rng | 41 +---- src/conf/schemas/nodedev.rng | 3 + src/hypervisor/virhostdev.c | 131 ++++++++------ src/libvirt_private.syms | 2 - src/node_device/node_device_udev.c | 4 + src/util/virusb.c | 160 ++++++------------ src/util/virusb.h | 22 +-- .../usb_device_1d6b_1_0000_00_1d_0.xml | 1 + ...ostdev-usb-address-port.x86_64-latest.args | 36 ++++ ...hostdev-usb-address-port.x86_64-latest.xml | 45 +++++ .../hostdev-usb-address-port.xml | 28 +++ ...tdev-usb-vendor-product.x86_64-latest.args | 35 ++++ ...stdev-usb-vendor-product.x86_64-latest.xml | 44 +++++ .../hostdev-usb-vendor-product.xml | 36 ++++ tests/qemuxmlconftest.c | 25 +++ tests/virusbtest.c | 149 +++++++++++----- .../sys_bus_usb/devices/1-1.5.3.1/devpath | 1 + .../sys_bus_usb/devices/1-1.5.3.3/devpath | 1 + .../sys_bus_usb/devices/1-1.5.3/devpath | 1 + .../sys_bus_usb/devices/1-1.5.4/devpath | 1 + .../sys_bus_usb/devices/1-1.5.5/devpath | 1 + .../sys_bus_usb/devices/1-1.5.6/devpath | 1 + .../sys_bus_usb/devices/1-1.5/devpath | 1 + .../sys_bus_usb/devices/1-1.6/devpath | 1 + .../sys_bus_usb/devices/1-1/devpath | 1 + .../sys_bus_usb/devices/2-1.2/devpath | 1 + .../sys_bus_usb/devices/2-1/devpath | 1 + .../sys_bus_usb/devices/usb1/devpath | 1 + .../sys_bus_usb/devices/usb2/devpath | 1 + .../sys_bus_usb/devices/usb3/devpath | 1 + .../sys_bus_usb/devices/usb4/devpath | 1 + 37 files changed, 631 insertions(+), 271 deletions(-) create mode 100644 tests/qemuxmlconfdata/hostdev-usb-address-port.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/hostdev-usb-address-port.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/hostdev-usb-address-port.xml create mode 100644 tests/qemuxmlconfdata/hostdev-usb-vendor-product.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/hostdev-usb-vendor-product.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/hostdev-usb-vendor-product.xml create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.3.1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.3.3/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.3/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.4/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.5/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5.6/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.5/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1.6/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/1-1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/2-1.2/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/2-1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb1/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb2/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb3/devpath create mode 100644 tests/virusbtestdata/sys_bus_usb/devices/usb4/devpath -- 2.39.5

Qemu pause-before-switchover and libvirt live migration
by Rogério Vinhal Nunes 02 Feb '26

02 Feb '26

Hello, I’m looking into the libvirt hooks that are available to make use of during a live migration, but there's only hooks on migration begin and migration end. On qemu directly I’m able to use pause-before-switchover migration capability to run a custom operation just before it moves to the destination, but within libvirt it seems that while this is leveraged internally, it’s not currently exposed to the client in a way I can use. Does anyone have any suggestions on how I could expose this to the client in a generic and sensible way? Thanks, Rogerio

[PATCH v2 0/1] x86: install modules-load.d file to load msr module
by Hector Cao 12 Jan '26

12 Jan '26

This submission is a follow-up (v2) of the discussion (RFC) that was happening at: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/ADJ4A... On x86, libvirt makes use of the API exposed by the msr kernel module to read the MSR (Model Specific Registers) values. On some Linux distros, this module is not loaded by default so libvirt might fail to read the MSR values and falls back to /dev/kvm to obtain these values. KVM might be behind in term of exposing all the values of the MSRs so using /dev/kvm is not ideal. This submission tries to make libvirt deploy the modules-load.d configuration so that linux loads the msr module at next boot. One caveat, libvirt installs only the file and does not trigger the load that is only done at next reboot, it is up to each distro to trigger immediately the load of the module without a reboot. v2: - only install the file when qemu driver is enabled Hector Cao (1): x86: install modules-load.d file to load msr module meson_options.txt | 1 + src/util/meson.build | 19 +++++++++++++++++++ src/util/modules-load.d/msr.conf | 1 + tools/virt-host-validate-qemu.c | 7 +++++++ 4 files changed, 28 insertions(+) create mode 100644 src/util/modules-load.d/msr.conf -- 2.45.2

[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 -
