Patches 01-05 were queued on my python-next branch:
https://github.com/ehabkost/qemu/commits/python-next

Please use python-next as base for v9, as I plan to submit a pull
request with the contents of python-next soon.

Please update the patches with Reviewed-bys from past revisions so I
know which patches I've already reviewed.

If someone has posted a R-b then it should be included in the next
revision unless you substantially modify that patch.

Thanks,

[Qemu-devel] [PATCH v8 00/13] scripts/qemu.py fixes and cleanups

[Amador Pahim]

Changes v1->v2:
 - Style fixes to make checkpatch.pl happy.
 - Rebased.
Changes v2->v3:
 - Fix typo in patch 3 ("qemu.py: make 'args' public") commit message.
Changes v3->v4:
 - Squash the 2 first commits since they are co-dependant.
 - Cleanup launch() and shutdown().
 - Reorder the commits, putting the rename of self._args first.
 - Rebased.
Changes v4->v5:
 - Break the cleanup commit into logical changes and include in the
   commit messages the rationale for making them.
Changes v5->v6:
 - Remove the commit to rename self._args.
 - Fix is_running() return before first call to maunch().
 - Use python logging system.
 - Include the full command line on negative exit code error message.
 - Use os.path.null instead of /dev/null.
 - Improve the control over the created/deleted files.
Changes v6->v7:
 - Split commits in self-contained/atomic changes.

 - Rebased.
 - Reorder commits to avoid break->fix sequence.
 - Split commits "use poll() instead of 'returncode'" and "refactor

 - Use LOG.warn() instead of LOG.debug() for the negative exit code
   message.
 - Fix the exception name called in commits "launch vm only if it's not
   running" and "don't launch again before shutdown()".
 - Minor style fixes.
