[PATCH v2 00/31] block/export: Add infrastructure and QAPI for block exports |
Date: |

We are planning to add more block export types than just NBD in the near
future (e.g. vhost-user-blk and FUSE). This series lays the ground for
this with some generic block export infrastructure and QAPI interfaces
that will allow managing all of them (for now add/remove/query).
As a side effect, qemu-storage-daemon can now map --export directly to
the block-export-add QMP command, similar to other command line options.
The built-in NBD servers also gains new options that bring it at least a
little closer to feature parity with qemu-nbd.
v2:
- Rebased on current master
- Fixed assumption of &blk_exp_nbd instead of drv in generic code [Max]
- Documented blk_exp_request_shutdown() better [Max]
- iotests 140: Fixed race between QMP return value and event [Max]
- Improved the commit message for patch 26
- Removed copy&paste error in deprecated.rst [Max]
- iotests: Take Sequence instead of positional arguments in
qemu_tool_pipe_and_status() [Max]
- iotests: Separate patch for qemu_nbd_list_log [Max]
- iotests 307: [Max]
* Allow more image formats
* Use sock_dir for the socket
* Use f-strings instead of % operator
* Log events after deleting an export
* Test force removing an export
