Re: [libvirt] [PATCH 1/8 v3] qemu: Set QEMU_AUDIO_DRV=none with -nographic

On my machine, a guest fails to boot if it has a sound card, but not graphical device/display is configured, because pulseaudio fails to initialize since it can't access $HOME. A workaround is removing the audio device, however on ARM boards there isn't any option to do that, so -nographic always fails. Set QEMU_AUDIO_DRV=none if no <graphics> are configured. Unfortunately this has massive test suite fallout. Add a qemu.conf parameter nographics_allow_host_audio, that if enabled will pass through QEMU_AUDIO_DRV from sysconfig (similar to vnc_allow_host_audio) --- I've snipped the actual test changes since the mail was too large. It was generated with roughly sed -i -e "s/LOGNAME=test /LOGNAME=test QEMU_AUDIO_DRV=none /" `grep "\-nographic" * | xargs`
