Re: [Qemu-devel] [PATCH RFC v7 7/7] qemu-iotests-s390x-fix-test-130

[Max Reitz <mreitz@redhat.com>]

Well, that's a peculiar commit title. :-)

I guess it's supposed to be "qemu-iotests: s390x: fix test 130"?

I think I mentioned before that I don't really like not taking the fact 
into account that there are other machine types, too. I'm still 
accepting it based on the fact that I think those machine types won't 
pass the tests right now anyway, so not caring for them in these case 
blocks won't break any tests, but it still feels like something we can 
avoid (like defaulting to virtio0 for any non-pc platform).

Anyway, because I seem to remember I accepted it before:

With the commit title fixed:

("commit $device_id" "(qemu)" would've worked, too, but it's fine the 
way _send_qemu_cmd works)
