The series builds on the zero detection features which I sent out before Christmas. I suggest grabbing my git tree to try it out without merging this dependency: https://github.com/stefanha/qemu/tree/image-streaming-api The image streaming HMP/QMP commands are documented in the patch and also described here: http://wiki.qemu.org/Features/LiveBlockMigration/ImageStreamingAPI The basic idea is to execute 'block_stream virtio0' while the guest is running. Progress can be monitored using 'info block-jobs'. When the streaming operation completes it raises a QMP event. Note: The last patch includes includes a Python test script called test-stream.py, I do not propose to merge it. When run in a QEMU source tree it performs basic image streaming QMP tests. v4: * Drop SQMP/EQMP docs from qmp-commands.hx [Luiz] * Follow QAPI doc conventions [Luiz] * Document QMP events in QMP/qmp-events.txt [Luiz] * Protect against hotplug, resize, eject, etc [Kevin] * Move block job functions from header to block.c [Kevin] * Return error from bdrg_change_backing_file() [Kevin] * Merge Marcelo's block_stream base partial streaming series [Marcelo] Marcelo Tosatti (4): block: add bdrv_find_backing_image add QERR_BASE_ID_NOT_FOUND block stream: add support for partial streaming add doc to describe live block operations Stefan Hajnoczi (11): coroutine: add co_sleep_ns() coroutine sleep function block: check bdrv_in_use() before blockdev operations block: add BlockJob interface for long-running operations block: add image streaming block job block: rate-limit streaming operations qmp: add block_stream command qmp: add block_job_set_speed command qmp: add block_job_cancel command qmp: add query-block-jobs blockdev: make image streaming safe across hotplug test: add image streaming test cases Makefile.objs | 2 + QMP/qmp-events.txt | 53 ++++++++++++ block.c | 133 ++++++++++++++++++++++++++++++ block.h | 5 + block/stream.c | 192 +++++++++++++++++++++++++++++++++++++++++++ block_int.h | 44 ++++++++++ blockdev.c | 199 ++++++++++++++++++++++++++++++++++++++++++++- docs/live-block-ops.txt | 58 +++++++++++++ hmp-commands.hx | 41 +++++++++ hmp.c | 68 +++++++++++++++ hmp.h | 4 + monitor.c | 13 +++ monitor.h | 2 + qapi-schema.json | 115 ++++++++++++++++++++++++++ qemu-coroutine-sleep.c | 38 +++++++++ qemu-coroutine.h | 6 ++ qerror.c | 8 ++ qerror.h | 6 ++ qmp-commands.hx | 24 ++++++ test-stream.py | 208 +++++++++++++++++++++++++++++++++++++++++++++++ trace-events | 9 ++ 21 files changed, 1227 insertions(+), 1 deletions(-) create mode 100644 block/stream.c create mode 100644 docs/live-block-ops.txt create mode 100644 qemu-coroutine-sleep.c create mode 100644 test-stream.py -- 1.7.7.3
