Commit 49d2e64 (machine: remove qemu_machine_opts global list) made
machine machine options specific to machine sub-type, leaving
the qemu_machine_opts desc array empty. Sadly this is the place
qmp_query_command_line_options is looking for supported options.

As a fix for for 2.3 the machine_qemu_opts are restored only
for the scope of qemu-config, bringing together all machines
properties. We need to find a better fix for 2.4.

I don't like this approach, but I wouldn't want to loose the
'options per machine type' feature. We'll find something better for 2.4/

I noticed the typo in subject :) maybe the maintainer that will take
it can fix this if no further work is necessary, of course.

Hi Tony,
I'll appreciate if you check that it works now.

I checked query-command-line-options and it returns the machine options for now.
No further changes should be necessary,

Thanks,
Marcel

It's a hack, but it avoids a regression.
Reviewed-by: Eric Blake <eblake@redhat.com>

I also tested that query-command-line-options on qemu.git + this patch
provided a superset of the options exposed by
2:qemu-system-x86-2.1.3-3.fc21.x86_64 as installed on Fedora 21, while
without this patch it had no options.

As discussed on the other thread, we may want a v2:

The problem is that the superset includes per-machine options, even for
machines where they don't apply.  I think it's better for 2.3 to be
conservative (advertise no less than before, so we don't regress) than
to lie (advertising something we don't support is risky).

I agree, this is the reason we wanted per-machine options, to not
lie to higher levels.

Thanks,
Marcel

Marcel,

I installed your patch on my system and it resolved the problem I was 
seeing.  I'm looking forward
to seeing how you are going to resolve this per machine.
