If QEMU_AUDIO_DRV is defined in the build host environment, several tests in qemuxml2xmltest fail. $ env | grep -i audio AUDIODRIVER=pulseaudio QEMU_AUDIO_DRV=pa SDL_AUDIODRIVER=pulse An example test failure with the above environment 907) QEMU XML-2-XML-active video-virtio-gpu-sdl-gl In 'libvirt/tests/qemuxml2xmloutdata/video-virtio-gpu-sdl-gl.xml': Offset 1244 Expect [v] Actual [audio id='1' type='pulseaudio'/> <v] Scrub QEMU_AUDIO_DRV from the environment before executing the tests in qemuxml2xmltest.
