Cleber Rosa d98205c586 iotests: make 083 specific to raw
While testing the Python 3 changes which touch the 083 test, I noticed
that it would fail with qcow2.  Expanding the testing, I noticed it
had nothing to do with the Python 3 changes, and in fact, it would not
pass on anything but raw:

 raw: pass
 bochs: not generic
 cloop: not generic
 parallels: fail
 qcow: fail
 qcow2: fail
 qed: fail
 vdi: fail
 vhdx: fail
 vmdk: fail
 vpc: fail
 luks: fail

The errors are a mixture I/O and "image not in xxx format", such as:

  === Check disconnect before data ===

  Unexpected end-of-file before all bytes were read
 -read failed: Input/output error
 +can't open device nbd+tcp://127.0.0.1:PORT/foo: Could not open 'nbd://127.0.0.1:PORT/foo': Input/output error

  === Check disconnect after data ===

 -read 512/512 bytes at offset 0
 -512 bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
 +can't open device nbd+tcp://127.0.0.1:PORT/foo: Image not in qcow format

I'm not aware if there's a quick fix, so, for the time being, it looks
like the honest approach is to make the test known to work on raw
only.

=== 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@nongnu.org with a CC:
to qemu-block@nongnu.org.
