Duh! my bad!
good log: http://dpaste.com/F2N5T8CT8
bad log: http://dpaste.com/6ECUHD2J8
The new log has a CLI flag
-audiodev id=audio1,driver=none
but the old log has an env variable
QEMU_AUDIO_DRV=none
which should be functionally identical, as QEMU will parse them both
to the same internal config.
The obvious difference in the logs which can cause your guest to fail
is the different QEMU version. The old log shows QEMU 5.2.0, while the
new log shows QEMU 6.0.0
With regards,
Daniel
