This series implements a new VIR_MIGRATE_POSTCOPY_RESUME flag (virsh
migrate --resume) for recovering from a failed post-copy migration.
You can also fetch the series from my gitlab fork (the last RFC patch is
missing there):
git fetch https://gitlab.com/jirkade/libvirt.git post-copy-recovery
Version 2:
- rebased and changed Since tags to 8.5.0
- even patches marked as "no change" can be a bit different as required
by rebasing to the current master or changes in other patches
- replaced a few patches with the "qemu: Drop QEMU_CAPS_MIGRATION_EVENT"
series:
- [03/80] qemu: Return state from qemuMonitorGetMigrationCapabilities
- [04/80] qemu: Enable migration events only when disabled
- [20/80] qemu: Use switch in qemuDomainGetJobInfoMigrationStats
- see individual patches for additional details
- most of the patches were acked in v1, the following patches did not earn
a Reviewed-by tag, were changed and lost the tag, or were added since the
previous version of this series:
- [03] Introduce VIR_DOMAIN_RUNNING_POSTCOPY_FAILED
- [04] qemu: Keep domain running on dst on failed post-copy migration
- [15] qemu: Restore async job start timestamp on reconnect
- [19] qemu: Use switch in qemuProcessHandleMigrationStatus
- [20] qemu: Handle 'postcopy-paused' migration state
- [21] qemu: Add support for postcopy-recover QEMU migration state
- [33] qemu: Introduce qemuMigrationDstFinishActive
- [34] qemu: Handle migration job in qemuMigrationDstFinish
- [45] qemu: Make qemuMigrationCheckPhase failure fatal
- [48] qemu: Use QEMU_MIGRATION_PHASE_POSTCOPY_FAILED
- [52] qemu: Implement VIR_MIGRATE_POSTCOPY_RESUME for Begin phase
- [60] qemu: Use autoptr for mig in qemuMigrationDstPrepareFresh
- [76] qemu: Implement VIR_DOMAIN_ABORT_JOB_POSTCOPY flag
- [79] Introduce VIR_JOB_MIGRATION_SAFE job type
- [80] qemu: Fix VSERPORT_CHANGE event in post-copy migration
- [81] RFC: qemu: Keep vCPUs paused while migration is in postcopy-paused
