[Qemu-devel] [PATCH 0/4] qemu-iotests: Test case for IO throttling

[Fam Zheng <famz@redhat.com>]

This series adds iotest case for IO throttling.

There is a new option "-a" for 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 11%, to make room for such
flexibility in order to improve determinism.


Fam Zheng (4):
  qemu-io: New option "-a" to aio_read and aio_write
  qemu-iotests: Add VM method qtest_cmd() to iotests.py
  qemu-iotests: Allow caller to disable underscore convertion for qmp
  qemu-iotests: Add 080 for IO throttling
