There is a change in qemu-io sub-commands "aio_read" and "aio_write", whi= ch makes the aio requests accounted and the statistics reflected in blocksta= ts. 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 Beno=C3=AEt. (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 writ= e.
