[PATCH v3 00/10] qemu: Rework internal active snapshots to use QMP commands

Changes to v2: - added few cleanups - added qemumonitorjson test cases for new commands - dropped duplicate capability flags - fixed bugs pointed out in v2 - rewritten logic for selecting snapshot images (both for creation/deletion) - fixed the logic to be fault tolerant same way as 'delvm' - allowed internal snapshots of VMs with UEFI - added explanation to all code with non-obvious implications Nikolai Barybin via Devel (4): qemu: monitor: Add plumbing for 'snaphot-save'/'snapshot-delete' QMP commands qemu: blockjob: Add job types for 'snapshot-save/delete' qemu: capabilities: Introduce QEMU_CAPS_SNAPSHOT_INTERNAL_QMP capability qemu snapshot: use QMP snapshot-save for internal snapshots creation Peter Krempa (6): qemuDomainObjWait: Annotate with G_GNUC_WARN_UNUSED_RESULT qemu: monitor: Store internal snapshot names from 'query-named-block-nodes' qemu snapshot: use QMP snapshot-delete for internal snapshots deletion qemuSnapshotActiveInternalDeleteGetDevices: Add warning when deleting inconsistent snapshot qemu: snapshot: Allow internal snapshots with PFLASH nvram news: mention internal snapshot changes NEWS.rst | 16 + src/qemu/qemu_block.c | 2 + src/qemu/qemu_blockjob.c | 7 + src/qemu/qemu_blockjob.h | 2 + src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 3 + src/qemu/qemu_domain.c | 10 + src/qemu/qemu_domain.h | 3 +- src/qemu/qemu_monitor.c | 30 ++ src/qemu/qemu_monitor.h | 17 + src/qemu/qemu_monitor_json.c | 79 ++++ src/qemu/qemu_monitor_json.h | 13 + src/qemu/qemu_snapshot.c | 358 +++++++++++++++++- tests/qemublocktest.c | 11 + .../bitmap/snapshots-internal.json | 298 +++++++++++++++ .../bitmap/snapshots-internal.out | 2 + .../caps_6.0.0_aarch64.xml | 1 + .../qemucapabilitiesdata/caps_6.0.0_s390x.xml | 1 + .../caps_6.0.0_x86_64.xml | 1 + .../caps_6.1.0_x86_64.xml | 1 + .../caps_6.2.0_aarch64.xml | 1 + .../qemucapabilitiesdata/caps_6.2.0_ppc64.xml | 1 + .../caps_6.2.0_x86_64.xml | 1 + .../caps_7.0.0_aarch64+hvf.xml | 1 + .../caps_7.0.0_aarch64.xml | 1 + .../qemucapabilitiesdata/caps_7.0.0_ppc64.xml | 1 + .../caps_7.0.0_x86_64.xml | 1 + .../qemucapabilitiesdata/caps_7.1.0_ppc64.xml | 1 + .../caps_7.1.0_x86_64.xml | 1 + tests/qemucapabilitiesdata/caps_7.2.0_ppc.xml | 1 + .../caps_7.2.0_x86_64+hvf.xml | 1 + .../caps_7.2.0_x86_64.xml | 1 + .../caps_8.0.0_riscv64.xml | 1 + .../caps_8.0.0_x86_64.xml | 1 + .../qemucapabilitiesdata/caps_8.1.0_s390x.xml | 1 + .../caps_8.1.0_x86_64.xml | 1 + .../caps_8.2.0_aarch64.xml | 1 + .../caps_8.2.0_armv7l.xml | 1 + .../caps_8.2.0_loongarch64.xml | 1 + .../qemucapabilitiesdata/caps_8.2.0_s390x.xml | 1 + .../caps_8.2.0_x86_64.xml | 1 + .../qemucapabilitiesdata/caps_9.0.0_sparc.xml | 1 + .../caps_9.0.0_x86_64.xml | 1 + .../caps_9.1.0_riscv64.xml | 1 + .../caps_9.1.0_x86_64.xml | 1 + tests/qemumonitorjsontest.c | 33 ++ 46 files changed, 895 insertions(+), 22 deletions(-) create mode 100644 tests/qemublocktestdata/bitmap/snapshots-internal.json create mode 100644 tests/qemublocktestdata/bitmap/snapshots-internal.out -- 2.46.0
