Subject: conf: allow to map sound device to host device
X-Git-Tag: v6.7.0-rc1~38
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9375bc7373caddd31f1ac5c14a69eac5096ea416;p=thirdparty%2Flibvirt.git

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='ich7'>
     <audio id='1'/>
  </sound>
  <audio id='1' 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.
