Paolo Bonzini ab68cdfaa9 qemu-iotests: fill streaming test image with data 
The TestStreamStop test case is racy; if the job completes before we can
cancel it, it fails.  If we remove the sleep the job will be canceled
before it has even started, and the test succeeds but it is also not
testing anything interesting.

But if the image is left sparse, then the job has really nothing to do.
For qcow2 it will read one L2-table, for raw it will issue a bunch of
ioctls.  This also falls under "not testing anything interesting", and
this may be happening right now (depending on the filesystem) since the
file protocol got an is_allocated method.

Filling the test image with data ensures that the test covers the
intended case.  It also slows down the test, which will be particularly
important after the next patch.

README 

=== This is the QEMU I/O test suite ===

* Intro

This package contains a simple test suite for the I/O layer of qemu.
It does not require a guest, but only the qemu, qemu-img and qemu-io
binaries.  This does limit it to exercise the low-level I/O path only
but no actual block drivers like ide, scsi or virtio.

* Usage

Just run ./check to run all tests for the raw image format, or ./check
-qcow2 to test the qcow2 image format.  The output of ./check -h explains
additional options to test further image formats or I/O methods.

* Feedback and patches

Please send improvements to the test suite, general feedback or just
reports of failing tests cases to qemu-devel@savannah.nongnu.org.
