This series improves the QMP SHUTDOWN and RESET events by adding
the ShutdownCause as additional parameter and splitting
the HOST_QMP reason into HOST_QMP_QUIT and HOST_QMP_SYSTEM_RESET
to be able to detect the difference between them when using '--no-reboot'

this is an alternative to my previous patches[1][2] which
added an exit-script/added a 'reset' argument to the events

this makes it possible to use the reason as return value
in a QMP event, such as SHUTDOWN

Please start your sentences with a capital letter and end them with
punctuation.

The patch's purpose could perhaps be stated a bit more clearly.  Let me
try:

  qapi: Turn ShutdownCause into a QAPI enum

  Needed so the patch after next can add ShutdownCause to QMP events
  SHUTDOWN and RESET.

Any particular reason for changing the tense from "prevents" to
"prevented"?

Because of this, order matters.  Your patch moves the enumeration away,
so readers get even less of a chance to catch this.

Let's add

       # Beware, shutdown_caused_by_guest() depends on enumeration order

here.  Adding it to the doc comment above would be no good, because
that's external documentation (it would end up in the QEMU QMP reference
manual).

it is interesting to know whether the shutdown cause was 'quit' or
'reset', especially when using --no-reboot

Are you sure it *is* interesting?  I suspect it *will be* only after the
next patch.

Let's see how these guys are used.

qemu_system_shutdown_request() and qemu_system_reset_request() put their
argument in @shutdown_requested or @reset_requested.  There's some
replay magic going on in qemu_system_shutdown_request().

main_loop_should_exit() retrieves them with qemu_shutdown_requested()
and qemu_reset_requested().  @shutdown_requested is only passed to
shutdown_caused_by_guest().  @reset_requested is only passed to
qemu_system_reset().  None of these functions is affected by your
change.  There's some replay magic going on in
qemu_system_reset_requested().

Xen's cpu_handle_ioreq() retrieves them with
qemu_shutdown_requested_get() and qemu_reset_requested_get().  None of
these functions is affected by your change.

Looks like ShutdownCause is overengineered[*]: we're only ever
interested in none, host, guest.  Your PATCH 3 will change that.  Okay,
but your commit message is misleading: this patch has no interesting
effect now.  The change becomes visible only after PATCH 3.

I'd swap PATCH 2 and 3, because that would make writing non-misleading
commit messages easier for me.

[*] Goes back to Eric's commit 7af88279e49..08fba7ac9b6, which were
surely done for a reason.  Perhaps I'm just confused.

hi,

yeah switching 2 and 3 makes sense, i guess i did it this way so that
i only have to touch the iotests one time

should i fix the iotests in both 2 and 3 when i switch them ?
(with 2 the reason gets added there, and 3 changes the reason)
or should i send an extra patch (4/4) that fixes only the iotests?
or only change them in 3/3 ?

when this is clear, i will send a v2 with all your remarks fixed

I still need to look more closely at the series, but in answer to your 
question,

Ideally, iotests should pass after each commit (reduces chance of 
confusion down the road when a 'git bisect' is trying to pinpoint a 
cause of some other iotest failure).  iotests are a bit fuzzier than 
'make check' in terms of how long things are allowed to be checked in 
with known failures (in part because iotests has so many different ways 
to be run, and not all configurations are run all the times, so many 
corner-case configurations end up broken over long stretches of commits 
without realizing it), so that at least gives you some flexibility. But 
if you KNOW the test is broken, and reordering the patches or tweaking 
the tests to pass is easy, then you might as well do it.

Churn in the tests as output changes is not too bad - especially if it 
shows that the patch is accomplishing its stated purpose of making the 
expected output nicer.  So having the test fixed in 2 to show the reason 
and again in 3 to show a change in the reason makes sense for a patch 
series.

this makes it possible to determine what the exact reason was for
a RESET or a SHUTDOWN

this patch also fixes the iotests
