Hi all! There is a new feature: reconnect on open. It is useful when start of vm and start of nbd server are not simple to sync.
v2: rebase on master. Also, I've discovered that I've sent downstream version of test which doesn't work here. So, the test is rewritten (with appropriate improvements of iotests.py) Vladimir Sementsov-Ogievskiy (8): block/nbd: move initial connect to coroutine nbd: allow reconnect on open, with corresponding new options iotests.py: fix qemu_tool_pipe_and_status() iotests.py: qemu_io(): reuse qemu_tool_pipe_and_status() iotests.py: add qemu_tool_popen() iotests.py: add and use qemu_io_wrap_args() iotests.py: add qemu_io_popen() iotests: add 306 to test reconnect on nbd open block/nbd.c | 173 +++++++++++++++++++++++++--------- tests/qemu-iotests/306 | 71 ++++++++++++++ tests/qemu-iotests/306.out | 11 +++ tests/qemu-iotests/group | 1 + tests/qemu-iotests/iotests.py | 56 +++++++---- 5 files changed, 246 insertions(+), 66 deletions(-) create mode 100755 tests/qemu-iotests/306 create mode 100644 tests/qemu-iotests/306.out -- 2.21.3
