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. @@ -7559,9 +7559,13 @@ qemuBuildCommandLine(virConnectPtr conn, * if you ask for nographic.

We do something similar with VNC by default, but we have a global qemu.conf override for that. /* Unless user requested it, set the audio backend to none, to * prevent it opening the host OS audio devices, since that causes * security issues and might not work when using VNC. */ if (cfg->vncAllowHostAudio) virCommandAddEnvPass(cmd, "QEMU_AUDIO_DRV"); else virCommandAddEnvString(cmd, "QEMU_AUDIO_DRV=none"); I think we probably want todo the same here, since it is in theory possible to make pulseaudio work for the QEMU driver.
