Re: [PATCH v2 2/4] conf: allow to map sound device to host device

Introduce a new device element "<audio>" which allows to map guest sound device specified using the "<sound>" element to specific audio backend. Example: <sound model='ich6'> <audio id='audio0'/> </sound> <audio id='audio' type='oss'> <input dev='/dev/dsp0'/> <output dev='/dev/dsp0'/> </audio> This block maps to OSS audio backend on the host using /dev/dsp0 device for both input (recording) and output (playback). OSS is the only backend supported so far. Signed-off-by: Roman Bogorodskiy <bogorodskiy(a)gmail.com&gt; --- docs/schemas/domaincommon.rng | 36 ++++++++
