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. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com&gt; --- On IRC Daniel suggested scrubbing QEM_AUDIO_DRV and SDL_AUDIODRIVER. Only QEM_AUDIO_DRV was needed to fix the test failure, but I can scrub the other one too if that's preferred. tests/qemuxml2xmltest.c | 1 + 1 file changed, 1 insertion(+) diff --git a/tests/qemuxml2xmltest.c b/tests/qemuxml2xmltest.c index 137f1871af..aff6ae9175 100644 --- a/tests/qemuxml2xmltest.c +++ b/tests/qemuxml2xmltest.c @@ -198,6 +198,7 @@ mymain(void) * using ADD_ENV_COPY, otherwise these tests may fail due to unexpected * values for these envvars */ g_setenv("PATH", "/bin", TRUE); + g_unsetenv("QEMU_AUDIO_DRV"); DO_TEST("minimal", NONE); DO_TEST_CAPS_LATEST("genid"); -- 2.30.1
