Qemu pause-before-switchover and libvirt live migration
by Rogério Vinhal Nunes 03 Feb '26

03 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 v6] qapi: net: deprecate vhostforce option
by Vladimir Sementsov-Ogievskiy 30 Jan '26

30 Jan '26

This option for tap and vhost-user netdevs doesn't make sense since long ago (10 years!), starting from commits: 1e7398a140f7a6 ("vhost: enable vhost without without MSI-X") 24f938a682d934 ("vhost user:support vhost user nic for non msi guests") Prior these commits, to enable kernel vhost-net, or vhost-user-net for some specific kind of guests (that don't have MSI-X support), you should have set vhostforce=on. Now guest type doesn't matter, all guests are equal for these options logic. For tap the current logic is: vhost=on / vhost=off : vhostforce ignored, doesn't make sense vhost unset : vhostforce counts, enabling vhost So you may enable vhost for tap several ways: - vhost=on - vhostforce=on - vhost=on + vhostforce=on - and even vhost=on + vhostforce=off - they are all equal. For vhost-user we simply ignore the vhostforce option at all in the code. Let's finally deprecate the extra options. Also, fix @vhostforce documentation everywhere to show the real picture, and update vhost-user test to not use deprecated option. While updating command line options, drop "experimental" word from "experimental in kernel accelerator". vhost-net is in production for years.

[PATCH v2 0/5] nwfilter: add nwfilter nftables driver
by Dion Bosschieter 17 Jan '26

17 Jan '26

This series aims to implement nftables as a backend driver for the nwfilter feature. The idea is that eventually it will replace the ebiptables driver and provide an easy way for users to switch from one driver to another. The first 2 patches are moving of functions and renames, meant to decouple nwfilter from the currently only existing ebiptables driver. The 3rd patch introduces the new nwfilter driver. After which nwfilter allows users to choose it in the 4th patch. The last patch introduces unit testing of the new nftables driver. - Implemented very basic nwfilter.conf reading and choosing a nwfilter driver based on the name of the drivers (nftables/ebiptables). Defaults to the nftables driver, based on the firewall_backend_priority meson option, following the bridge driver logic. - Resolves issue https://gitlab.com/libvirt/libvirt/-/issues/603 benchmarks showed that the amount of iifname jumps for each interface with is the cause for this. Switched the nftables driver towards a vmap (verdict map) so we can have 1 rule that jumps to the correct root input/output chain per interface. Which improves throughput as when the number of interface check and jump rules increases the throughput decreases. The issue describes the interface matching works using the interface name and the majority of the effort is the strncpy, this commit also switches nftables to an interface_index compare instead. However, just using the interface_index is not enough, the amount of oif and iif jump rules causes quite a performance issue, the vmap instead solves this. - Split rules into separate tables: "libvirt-nwfilter-ethernet" and "libvirt-nwfilter-other" to preserve existing firewall behavior. - Reworked chain logic for clarity with root -input/-output chains per interface. input in the VM interface is filtered in the -input chain(s), output out of the VM inteface is filtered in the -output chain(s). - Stuck with prerouting and postrouting as hooks for input / output on the -ethernet and -other table. This makes it easier to merge the tables in the future. Saving management of two tables and decreasing the amount of tables a packet sees. Currently ebtables filtering happens via PREROUTING and POSTROUTING hooks, while ip/ip6tables filtering happens in the output/forward hooks. - Stuck with 2 tables for compatibility reasons with eb iptables, unifying into 1 table will break users firewall definitions, which depend on being able to do accepts on ethernet rules (which currently get defined via ebtables) and additional filtering via the ip rules (which currently get defined via ip(6)tables). The nwfilter_nftables_driver keeps splitting the ethernet and non ethernet (other) rules in seperate tables "libvirt-nwfilter-ethernet" and "libvirt-nwfilter-other". - Rewrote chain logic, so it is easier to understand, input in the VM interface is filtered in the -input chain(s), output out of the VM inteface is filtered in the -output chain(s). -ethernet and -other table follow the same style and hook in the same way. - Simplified conntrack handling: rules with accept+conntrack are duplicated to the opposite chain for symmetric behavior, to support the existing ebiptables logic. - Firewall updates continue use tmp names for atomic replacement. Unsupported nwfilter features (for now): - STP filtering - Gratuitous ARP filtering - IPSets (potential future support via nft sets) - Reject due to filtering in pre/postrouting, using drop instead of reject, copying logic from existing ebiptables ebtables actions Future improvements: - Use `nft -f` for atomic rule application. - Optional single-table mode via nwfilter.conf. - Optimize boot phase with chain hash comparison. --- Changes in v2: - Rename {ebip,nf}tables specific test files in 1 directory instead of seperating them in different directories. - Added default nwfilter.conf file in git, documented including augeas files - Replaced hardcoding of default driver based on existing firewall_backend_priority meson option. - Added nwfilter_driver_conf.{h,c} for configuration handling, to match the common pattern used in other drivers.

[PATCH 00/29] qemu: Implement support for uefi-vars device and firmwares
by Andrea Bolognani 16 Jan '26

16 Jan '26

This series makes it possible to use Secure Boot with aarch64 VMs. https://issues.redhat.com/browse/RHEL-82645 It needs a prerequisite series[1] to be applied first. Note that, while I consider the entire series to be ready for review, there are two patches that are marked as DONOTMERGE: that's because they respectively implement support for a JSON firmware descriptor syntax extension that has not yet been approved, and import into the tree firmware descriptor that are not yet part of the Fedora edk2 package. The latter depends on the former, of course, for which patches have been posted[2] to the QEMU mailing list.

[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 -

[PATCH] qemu: Add stop hook support for domain shutdown
by Mitchel Humpherys 07 Jan '26

07 Jan '26

Introduce a new QEMU hook operation "stop" that is called before a domain is terminated (via virsh shutdown or virsh destroy). This allows external scripts to perform cleanup or veto the stop process by returning a non-zero exit code. The hook is called as: /etc/libvirt/hooks/qemu <guest_name> stop begin - The full domain XML is provided on stdin. Example qemu hook that protects domains from being stopped (to be dropped in /etc/libfirt/hooks/qemu.d/10-vm-protection or similar): ```bash #!/bin/bash # Protection hook - vetos domain stops for domains listed in # /etc/libvirt/protected-domains set -euo pipefail readonly PROTECT_DIR="/etc/libvirt" readonly DOMAIN_NAME="${1:-}" readonly OPERATION="${2:-}" # Only act on stop operation if [[ "$OPERATION" != "stop" ]]; then exit 0 fi readonly PROTECT_LIST="${PROTECT_DIR}/protected-domains" if [[ -f "$PROTECT_LIST" ]]; then # Read file, strip comments and empty lines, check for exact domain match if grep -Fxq -- "$DOMAIN_NAME" <(sed -e 's/#.*$//' -e '/^[[:space:]]*$/d' "$PROTECT_LIST"); then logger -t libvirt-hook-test "20-protection: BLOCKING stop for protected domain '$DOMAIN_NAME'" echo "$(date '+%Y-%m-%d %H:%M:%S'): BLOCKED stop for '$DOMAIN_NAME'" \ >> /tmp/libvirt-test-logs/protection.log printf 'vm-protection: stop blocked for %s\n' "$DOMAIN_NAME" >&2 exit 1 fi fi exit 0 ``` With a list of domains to protect in /etc/libvirt/protected-domains. With the above hook in place, attempting to destroy a domain listed in /etc/libvirt/protected-domains will fail: ``` > virsh list --all Id Name State ------------------------------- 2 protected-vm running - test-vm shut off > virsh destroy protected-vm error: Failed to destroy domain 'protected-vm' error: Hook script execution failed: internal error: Child process (LC_ALL=C LD_LIBRARY_PATH=/opt/libvirt-test/lib/x86_64-linux-gnu:/opt/libvirt-test/lib PATH=/usr/local/sbin:/usr/local/bin:/usr/bin HOME=/root USER=root LOGNAME=root /opt/libvirt-test/etc/libvirt/hooks/qemu.d/20-protection protected-vm stop begin -) unexpected exit status 1: vm-protection: stop blocked for protected-vm > virsh list --all Id Name State ------------------------------- 2 protected-vm running - test-vm shut off ``` Signed-off-by: Mitchel Humpherys <mitch.special(a)gmail.com> --- docs/hooks.rst | 14 +++++++++++--- src/qemu/qemu_process.c | 17 +++++++++++++++++ src/util/virhook.c | 1 + src/util/virhook.h | 1 + 4 files changed, 30 insertions(+), 3 deletions(-) diff --git a/docs/hooks.rst b/docs/hooks.rst index e1745b8cc7..5ae03a36cd 100644 --- a/docs/hooks.rst +++ b/docs/hooks.rst @@ -202,9 +202,17 @@ operation.

[PATCH v4 0/9] Enable mshv support for Qemu domains
by Praveen K Paladugu 07 Jan '26

07 Jan '26

This patch set introduces changes within libvirt to lauch Qemu guests with Microsoft Hypervisor(mshv). Qemu exposes this capability as 'mshv' accelerator type. Below is an excerpt of domain XML with mshv accelerator.: ``` <domain type='hyperv'> <name>qemu_mshv_test</name> <os> <type machine='q35'>hvm</type> </os> ... ``` 'mshv' accelerator within Qemu translates to 'hyperv' domains in Libvirt. Changs in v4: - Adopted `query-accelerators` API to get mshv capabilities. - Fixed virtytpe parsing in schemas. Chages in v3: - Addressed review comments on v2. - fixed qemucapabilitiestest case - Added a case to qemuxmlconftest Changes in v2: - Addressed review comments on v1. - Added a test to verify mshv capabilities. Eugene Fedorenko (1): qemu: Append mshv to hwaccel list. Praveen K Paladugu (8): qemu: Introduce mshv capabilities qemu: Query and use mshv capabilities qemu: use mshv accel for hyperv domains qemu: conditionally add /dev/mshv to acl conf: Fix virttype handling in schemas tests: Add domaincaps case for mshv tests: qemucapabilities: Introduce MSHV capability tests:qemuxmlconftest: Add case for hyperv domains src/conf/schemas/basictypes.rng | 22 + src/conf/schemas/capability.rng | 14 +- src/conf/schemas/domaincommon.rng | 23 +- src/qemu/qemu_capabilities.c | 39 +- src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 6 + src/qemu/qemu_command.c | 4 +- src/qemu/qemu_namespace.c | 2 + src/qemu/qemu_process.c | 2 +- .../qemu_10.2.0-q35.x86_64+mshv.xml | 222 + .../qemu_10.2.0-tcg.x86_64+mshv.xml | 2334 + .../qemu_10.2.0.x86_64+mshv.xml | 222 + .../caps_10.2.0_x86_64+mshv.replies | 45176 ++++++++++++++++ .../caps_10.2.0_x86_64+mshv.xml | 3212 ++ .../qemucaps2xmloutdata/caps.x86_64+mshv.xml | 29 + ...86_64-q35-headless.x86_64-latest+mshv.args | 48 + ...x86_64-q35-headless.x86_64-latest+mshv.xml | 87 + ...mshv-x86_64-q35-headless.x86_64-latest.err | 1 + .../mshv-x86_64-q35-headless.xml | 35 + tests/qemuxmlconftest.c | 5 + 20 files changed, 51446 insertions(+), 38 deletions(-) create mode 100644 tests/domaincapsdata/qemu_10.2.0-q35.x86_64+mshv.xml create mode 100644 tests/domaincapsdata/qemu_10.2.0-tcg.x86_64+mshv.xml create mode 100644 tests/domaincapsdata/qemu_10.2.0.x86_64+mshv.xml create mode 100644 tests/qemucapabilitiesdata/caps_10.2.0_x86_64+mshv.replies create mode 100644 tests/qemucapabilitiesdata/caps_10.2.0_x86_64+mshv.xml create mode 100644 tests/qemucaps2xmloutdata/caps.x86_64+mshv.xml create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.x86_64-latest+mshv.args create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.x86_64-latest+mshv.xml create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.x86_64-latest.err create mode 100644 tests/qemuxmlconfdata/mshv-x86_64-q35-headless.xml -- 2.51.0

[PATCH] libvirt-guests.service: use Type=exec
by Antonio Terceiro 07 Jan '26

07 Jan '26

Type=oneshot means that the service is only considered started after the main process exits. In setups where libvirt-guests is configured to be used and imposes a delay on the startup of guests, this will cause systemd to report a quite high boot time as it will wait until all guests have booted, plus all the delay between them. High boot times are often reported as issues in monitoring systems, and require operator attention, while in this case there is not really an issue with the system, it's just doing what it was configured to do. With Type=exec, the service is considered started right after the main process is *started*, but the boot process will not wait for it. Having other units depend on libvirt-guests.service finishing was already not reliable because one cannot know how long the OS inside each guest takes to boot, and libvirt-guests already does not wait for them to be in any particular state.

[PATCH 00/36] qemu: Improvements and fixes to firmware selection
by Andrea Bolognani 06 Jan '26

06 Jan '26

This series improves validation so that more nonsensical configurations are rejected, fixes a number of scenarios in which user-provided attributes were getting overwritten by the firmware selection process, and overall makes things more predictable and reliable. Notably, it addresses the inability of starting confidential VMs on aarch64, which was reported[1] some time ago. It is also a prerequisite of another series that I will post shortly, which introduces support for the uefi-vars QEMU device and thus makes it possible to use Secure Boot for aarch64 VMs. Since all these fixes and improvements make sense on their own, and there is a little bit of work still needed on the QEMU/edk2 side before the other series can be merged, I decided to post this one separately instead of lumping them together. It's not like it's not meaty enough on its own anyway :) [1] https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/D5UD… Andrea Bolognani (36): qemu_firmware: Drop support for kernel

[PATCH v2 0/5] cover: RFE libvirt secret encryption on disk
by Arun Menon 06 Jan '26

06 Jan '26

Libvirt secrets are stored unencrypted on the disk. With this series we want to start encrypting the secrets. 1. Introduce the GnuTLS decryption wrapper functions that work exact opposite to the encryption wrappers. 2. Add a new service called virt-secrets-init-encryption, that is linked to the virtsecretd and libvirtd service. virtsecretd and libvirtd services only starts after the new service generates a random encryption key. 3. Add a new secret.conf configuration file that helps user to set a. secrets_encryption_key - allows the user to specify the encryption key file path, in case the default key is not to be used. b. encrypt_data - set to 0 or 1. If set to 1, then the newly added secrets will be encrypted. 4. Rename the file name attribute in virSecretObj structure to secretValueFile. 5. Once we have the encryption key, and a reliable way to tell the daemon what encryption scheme the secret object is using, we can encrypt the secrets on disk and store them in <uuid>.<encryption_scheme> format. It is important to note that if the encryption key is changed between restarts, then the respective secret will not be loaded by the driver. This is a sincere attempt to improve upon the already submitted patch https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/KE6G… Resolves: https://issues.redhat.com/browse/RHEL-7125 --- Changes in v2: - Fixed a regression in the decryption logic. ciphertext length was incorrectly calculated. - Removed virSecretEncryptionScheme enum. It is no longer required. All the changes will be done at one place i.e. schemeInfo array. In future we can append to the array, when we want to add new cipher modes. - Add Requires= and After= directives in libvirtd service. Remove unnecessary configuration settings from src/secret meson.build. - Other minor refactoring and header include fix. Arun Menon (5): util: Add support for GnuTLS decryption secret: Set up default encryption secret key for the virtsecretd service secret: Add secret.conf configuration file and parse it secret: Rename virSecretObj structure attribute from base64File to secretValueFile secret: Add functionality to load and save secrets in encrypted format include/libvirt/virterror.h | 1 + libvirt.spec.in | 7 + po/POTFILES | 1 + src/conf/virsecretobj.c | 183 ++++++++++++++---- src/conf/virsecretobj.h | 18 +- src/libvirt_private.syms | 1 + src/meson.build | 1 + src/remote/libvirtd.service.in | 4 + src/secret/libvirt_secrets.aug | 40 ++++ src/secret/meson.build | 31 +++ src/secret/secret.conf.in | 14 ++ src/secret/secret_config.c | 179 +++++++++++++++++ src/secret/secret_config.h | 40 ++++ src/secret/secret_driver.c | 34 +++- src/secret/test_libvirt_secrets.aug.in | 6 + .../virt-secret-init-encryption.service.in | 8 + src/secret/virtsecretd.service.extra.in | 8 + src/util/vircrypto.c | 126 +++++++++++- src/util/vircrypto.h | 8 + src/util/virerror.c | 3 + tests/vircryptotest.c | 65 +++++++ 21 files changed, 728 insertions(+), 50 deletions(-) create mode 100644 src/secret/libvirt_secrets.aug create mode 100644 src/secret/secret.conf.in create mode 100644 src/secret/secret_config.c create mode 100644 src/secret/secret_config.h create mode 100644 src/secret/test_libvirt_secrets.aug.in create mode 100644 src/secret/virt-secret-init-encryption.service.in -- 2.51.1

[RFC 00/10] qom: Support marking object properties as deprecated
by Zhao Liu 06 Jan '26

06 Jan '26

Hi, This RFC is the follow-up work of v2.6 & v2.7 machines' removal [*], and tries to introduce a general way to provide deprecation hint for external user. Its core idea is to detect external property settings (as well as specific internal property settings, such as the compat property). I think deprecated properties and internal-only properties are quite similar, as both require consideration of external property usage. But the former only triggers a warning, while the latter stops all external access attempts. For simplicity, this RFC series only considers deprecated properties. Brief Introduction ================== Now the common (but a bit fragmented) way to mark a property deprecated is to add the warning in its accssors, or just document the deprecation in docs/about/deprecated.rst without any hint when someone touches that property. Ideally, it's better to provide some hints to external user when he tries to set the property via command line or HMP. But this is pretty inconvenient (even impossible) for such qdev properties, which are defined via DEFINE_PROP_* macros in the Property array. For qdev properties, their accessors are provided by pre-defined PropertyInfo, so that it's possible to modify PropertyInfo for a single "deprecated" property. Then it's necessary to introduce property flags to mark some properties as deprecated, and to check the property flags when set the property, thereby to print a deprecation warning. This not only benefits traditional qdev properties but also helps the deprecation of generic objects. Note, internal attempt (except the compat case) should not trigger the deprecation warning but external user should see the deprecation information. I think the most complex part is identifying the paths for property settings (both external command-line options and internal specific configurations). This series currently covers the following scenarios (which I consider to be particularly important): External cases: 1) External global properties: * -global command line option. * -cpu command line features. * suger properties from object_compat_props[2] 2) External ("TYPE_USER_CREATABLE") object: * -object command line used for external ("TYPE_USER_CREATABLE") object. 3) External device: * -device command line - parsed based on keyval or json. 4) External machine options: * -machine command line - parsed based on keyval. 5) External accelerator options: * -accel command line. 6) HMP command: * "qom-set" command. Internal cases: 1) internal global properties: * compat properties from object_compat_props[0,1]. 2) Internal machine options: * Builtin default machine options string: MachineClass::default_machine_opts - parsed based on keyval, too. In fact, there are still some special device command lines that haven't been considered yet. But I believe the remaining cases can be gradually expanded? If this approach is feasible, it's possible to further introduce an "internal" flag to prevent external access to compat property.

[PATCH v3 0/7] qemu: Implement support for iommufd
by Nathan Chen 06 Jan '26

06 Jan '26

From: Nathan Chen <nathanc(a)nvidia.com> Hi, This is a follow up to the second patch series [0] for using iommufd to propagate DMA mappings to the kernel for VM-assigned host devices in a qemu VM. We add 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: <devices> ... <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> ... </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: -object '{"qom-type":"iommufd","id":"iommufd0","fd":"24"}' \ -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 v2: - Set per-process memory accounting mode for iommufd - Separated out formatting of iommufd object from qemuBuildHostdevCommandLine - Placed hostdev private data implementation in a separate commit - Allocate hostdev private data unconditionally - Compare FDs against -1 - Integrated callback function in virQEMUDriverPrivateDataCallbacks for qemuDomainHostdevPrivateNew - Dropped qemuProcessCloseVfioFds - Addressed other feedback from v2 (formatting, includes, etc.) - Revised seclabel logic to be device-specific for AppArmor and to allow paths for SELinux/DAC Thanks to Ján Tomko for sharing some of the above changes in a personal repo. I have included changes directly from that repo and added Suggested-by or Signed-off-by tags on various commits containing the changes.

[PATCH 0/9] bhyve: arm64 guest support
by Roman Bogorodskiy 06 Jan '26

06 Jan '26

This series includes a minimal number of changes to allow running bhyve arm64 guests. Bhyve on amd64 and arm64 has slightly different sets of supported devices, and a different syntax for some devices. Specifically, bootrom and consoles are configured without the LPC controller, used for amd64, but using the "-o" argument, i.e. "-o bootrom=<bootrom>" and "-o console=<console>". This series moves quite a significant amount of test data files. I tried to isolate that into separate commit with a minimal set of related changes. While this series enables running arm64, there are more items to work on: - On arm64, bhyve normally uses /usr/local/share/u-boot/u-boot-bhyve-arm64/u-boot.bin bootrom. Autofill code should be updated to automatically use that if no path was specified. - Bhyve capabilities probing uses `bhyve -s 0,<device>` and parsing error message to see if a device is supported. Using `bhyve -s help` that lists supported devices should be more accurate and robust. - UTC clock is not supported on bhyve/arm64. I wasn't able to figure out yet how to make libvirt not using it by default, so currently arm64 guests require <clock offset='localtime'/> I plan to address these issues in a separate series.

[PATCH 0/3] Add 'scalable_mode' and 'first_stage' attributes to intel IOMMU
by Zhenzhong Duan 26 Dec '25

Hi, This adds 'scalable_mode' and 'first_stage' attributes to intel IOMMU so that emulated device can run with first stage translation. This is based on Nathan Chen's iommufd series v2[1], so for passthrough device, nested tranlation is enabled automatically with below config: <iommu model='intel'> <driver caching_mode='on' iotlb='on' scalable_mode='on' first_stage='on'/> </iommu> Tests: Basic net card passthrough libvirt selftest Thanks Zhenzhong [1] https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/KFYU… Zhenzhong Duan (3): qemu: Introduce scalable_mode and first_stage capabilities conf: add support for 'scalable_mode' and 'first_stage' attributes to intel IOMMU qemu: Add command line support for scalable mode and first stage of virtual vtd docs/formatdomain.rst | 8 +++++ src/conf/domain_conf.c | 35 ++++++++++++++++++- src/conf/domain_conf.h | 2 ++ src/conf/domain_validate.c | 6 ++++ src/conf/schemas/domaincommon.rng | 10 ++++++ src/qemu/qemu_capabilities.c | 4 +++ src/qemu/qemu_capabilities.h | 2 ++ src/qemu/qemu_command.c | 2 ++ src/qemu/qemu_validate.c | 12 +++++++ .../caps_10.0.0_x86_64+amdsev.xml | 2 ++ .../caps_10.0.0_x86_64.xml | 2 ++ .../caps_10.1.0_x86_64+inteltdx.xml | 2 ++ .../caps_10.1.0_x86_64.xml | 2 ++ .../caps_10.2.0_x86_64.xml | 2 ++ .../caps_6.2.0_x86_64.xml | 1 + .../caps_7.0.0_x86_64.xml | 1 + .../caps_7.1.0_x86_64.xml | 1 + .../caps_7.2.0_x86_64+hvf.xml | 1 + .../caps_7.2.0_x86_64.xml | 1 + .../caps_8.0.0_x86_64.xml | 1 + .../caps_8.1.0_x86_64.xml | 1 + .../caps_8.2.0_x86_64.xml | 1 + .../caps_9.0.0_x86_64.xml | 1 + .../caps_9.1.0_x86_64.xml | 1 + .../caps_9.2.0_x86_64+amdsev.xml | 1 + .../caps_9.2.0_x86_64.xml | 1 + 26 files changed, 102 insertions(+), 1 deletion(-) -- 2.47.3

[ 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.
