[Qemu-devel] [PATCH v3 0/5] qemu-iotests: Test case for IO throttling |

This series adds iotest case for IO throttling.
There is a change in qemu-io sub-commands "aio_read" and "aio_write", which
makes the aio requests accounted and the statistics reflected in blockstats.
Note that IO throttling implementation allows overcommiting of requests, so the
actual IO happened in a time unit may be a bit larger than given limits. In the
test case, the stats numbers are compared against 110%, to make room for such
flexibility in order to improve determinism.
v3: Address comments from Benoît. (Thanks for the review!)
[02/05] qtest: Add scripts/qtest/qtest.py
Fix comments.
Fix socket close order.
Removed unused lines.
[03/05] qemu-iotests: Add VM method qtest() to iotests.py
Remove duplicated VM.qtest definition.
[05/05] qemu-iotests: Add 080 for IO throttling
Check for lower bound (0.9 * limit * seconds).
Remove unused lines.
Fix checking of total bps and iops by adding up read and write.
Fam Zheng (5):
qemu-io: Account IO by aio_read and aio_write
qtest: Add scripts/qtest/qtest.py
qemu-iotests: Add VM method qtest() to iotests.py
qemu-iotests: Allow caller to disable underscore convertion for qmp
qemu-iotests: Add 080 for IO throttling
