[libvirt] [PATCH 0/4] incremental backup: QMP interactions

I'm trying to break my incremental backup work into smaller pieces so I can make progress and actually get some code committed, while I continue to hammer away at preparing a v9 series that addresses even more review comments and things learned during testing. These few patches represent the bulk of 14-15/21 from v8, except that the operation to update Checkpoint size must come later in the series when checkpoint_conf.h is ready. Another reason to commit this now, even without the incremental backup clients of the new capabilities, is that capability additions tend to be a conflict magnet, so I'd rather stabilize this and reduce the amount of rebase work I have been doing. Changes from v8: - improve testing of nbd-server-start - split up QMP changes into more manageable pieces - address formatting review comments Eric Blake (4): backup: Prepare for Unix sockets in QMP nbd-server-start backup: Add two new qemu capabilities backup: Add new qemu monitor bitmap backup: Add new parameters to qemu monitor nbd-server-add src/qemu/qemu_capabilities.h | 4 + src/qemu/qemu_monitor.h | 29 +++- src/qemu/qemu_monitor_json.h | 24 ++- src/qemu/qemu_capabilities.c | 6 + src/qemu/qemu_migration.c | 9 +- src/qemu/qemu_monitor.c | 74 ++++++++- src/qemu/qemu_monitor_json.c | 149 +++++++++++++++++- .../caps_4.0.0.aarch64.xml | 2 + .../qemucapabilitiesdata/caps_4.0.0.ppc64.xml | 2 + .../caps_4.0.0.riscv32.xml | 2 + .../caps_4.0.0.riscv64.xml | 2 + .../qemucapabilitiesdata/caps_4.0.0.s390x.xml | 2 + .../caps_4.0.0.x86_64.xml | 2 + tests/qemumonitorjsontest.c | 60 ++++++- 14 files changed, 341 insertions(+), 26 deletions(-) -- 2.20.1
