[Qemu-devel] [PATCH v2 0/3] qemu-iotests: add image streaming tests

[Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>]

This series adds the image streaming test suite to qemu-iotests.  It covers the
'block_stream', 'block_job_cancel', 'block_job_set_speed', and
'query-block-jobs' QMP interfaces.

Since these tests involve QMP it is no longer convenient to write them in bash.
Instead these tests are written in Python and make use of the existing
QMP/qmp.py module.  In order to achieve this, it adds an iotests Python module
that handles interaction with the qemu-iotests framework.

If you want to review using a top-down approach, I suggest reading this series
backwards, starting from Patch 3 which introduces 030, the image streaming test
suite.

Or if you like the bottom-up approach:

* Patch 1 exports TEST_DIR from qemu-iotests so test executables can learn the
  temporary directory path.

* Patch 2 adds the iotests.py module, which brings together qemu-iotests,
  unittest, and QEMU in a way that is easy to consume in Python.

* Patch 3 adds 030, the image streaming test suite.

Tests pass successfully with both qcow2 and qed on qemu.git/master.

v2:
 * Python 2.6 compatibility, use public unittest.TextTestRunner [Kevin]
