model
, which specifies what real sound device is emulated. Valid values are specific to the underlying hypervisor, though typical choices are 'es1370'
, 'sb16'
, 'ac97'
, and 'ich6'
. In addition, a sound element with ich6 model can have optional sub-elements codec

(advertises a line-in and a line-out) and 'micro'
(advertises a speaker and a microphone).
