[PATCH v1 1/1] qemu: add support for zero-page-detection migration parameter
by Tejus GK 21 Oct '26

21 Oct '26

QEMU supports a migration parameter to determine whether zero-page checking should be performed and if yes, where it should be performed (i.e., in the main migration thread or multifd threads). Add support for this parameter in libvirt.

[libvirt PATCH] qemu: re-introduce debug-threads capability

20 Oct '26

From: Ján Tomko <jtomko(a)redhat.com> The option is being removed from QEMU. Since QEMU 11.2 it has been a no-op and always enabled. Stop assuming it's always present so that running VMs won't break with the new QEMU versions.

[PATCH V2] qemu: emit UNDEFINED event when undefining source after migration
by Jim Fehlig 20 Oct '26

20 Oct '26

From: Jim Fehlig <jfehlig(a)suse.com> When migrating with VIR_MIGRATE_UNDEFINE_SOURCE, qemuMigrationSrcConfirm() and qemuMigrationSrcPerformJob() delete the domain's persistent config on the source host but never emit a VIR_DOMAIN_EVENT_UNDEFINED lifecycle event. Applications relying solely on domain events never learn the domain was undefined on the source. Add a new UNDEFINED event detail named 'VIR_DOMAIN_EVENT_UNDEFINED_MIGRATED", and include it when emitting an UNDEFINED event after a successful migration with VIR_MIGRATE_UNDEFINE_SOURCE flag.

From: sayaoailun <guojianwei007(a)126.com> When comparing symlink targets in qemuNamespaceMknodOne(), the code directly compares the raw symlink target (which may be a relative path) with data->target (which was normalized to an absolute path in qemuNamespaceMknodItemInit()). This causes false mismatches when the symlink uses a relative path. Fix this by normalizing the symlink target to an absolute path before comparison, using the same logic as qemuNamespaceMknodItemInit(). This fixes VM startup failure with LVM volumes that use relative symlinks, which reported 'Unable to remove symlink: Device or resource busy'.

[PATCH libvirt v2 0/4] s390x CPU model compatibility check for incoming migration
by Rorie Reyes 20 Oct '26

20 Oct '26

Changelog: V2 - - patch 1 (new patch, split from v1 patch 1): - fix result string to enum mapping; move into monitor layer - update unit test for all four result strings - report unknown result strings as errors - patch 2: - squash v1 patch 2 (propagate responsibleProps through monitor layer) into this patch - drop GenericError interception block - fix virReportError overwriting error from virJSONValueArrayToStringList - update qemu_driver.c caller to pass NULL - patch 3 (split from v1 patch 1): - add block scopes per subtest - use STRNEQ_NULLABLE - drop "superset + type" test case - fix bullet list to only include cases added by this patch - patch 4: - replace qemuCPUModelCompatResult enum with virCPUCompareResult - move "type" property filtering into qemuProcessCheckS390CPU() - wire check into qemuProcessUpdateGuestCPU() instead of qemu_migration.c - simplify qemuConnectCPUModelComparison() to delegate to new helper - report unknown results as errors ------------------- This series extends the qemu-cpu-model-comparison QMP interface in libvirt to surface the "responsible-properties" array returned by QEMU, and uses that information to perform a pre-flight CPU compatibility check on s390x before an incoming migration is accepted. Background ---------- On x86, QEMU rejects an incompatible CPU model at domain start time and produces a meaningful error. On s390x the guest starts successfully but may fail later in an opaque way if the destination host lacks required CPU features. This series brings s390x in line with x86 by catching the incompatibility early, aborting the migration cleanly, and reporting exactly which CPU properties are responsible. Functional Test Instructions ----------------------------- Prerequisites: - Two s390x hosts (source and destination) with different CPU feature levels from the same generation lineage (e.g. z16 and z17). - libvirt and QEMU built from this series on both hosts. - QEMU must support the query-cpu-model-comparison QMP command (QEMU >= 5.1). Test case 1 — Incompatible CPU model is rejected cleanly: 1. Define a guest on the source host using a custom s390x CPU model that includes features not present on the destination host. 2. Initiate a live migration to the destination host: virsh migrate --live <domain> qemu+ssh://dest-host/system 3. Expected result: migration fails immediately with a clear libvirt error before QEMU starts on the destination, e.g.: error: operation failed: guest CPU model is a newer generation than the destination host CPU model or, for a feature-level mismatch within the same generation: error: operation failed: destination host CPU model is missing features required by the guest CPU model: <prop1>, <prop2> 4. Verify the guest is still running cleanly on the source host: virsh domstate <domain> # should report: running Test case 2 — Compatible CPU model migrates successfully: 1. Define a guest using a CPU model fully supported by the destination (e.g. gen16a-base guest migrating to a gen17 host). 2. Initiate the same live migration. 3. Expected result: migration completes successfully with no errors.
