Interesting. What about Display (ie ui-*) ? I mean how do I figure out from, 
say, libvirt,
everything that QEMU can do in terms of display, which drivers are actually 
installed?

Same for block...

with the increasing modularization of QEMU we should I presume strengthen the 
discoverability of QEMU capabilities right?
This way we can configure once, and install just what is needed to match the 
user requirements, or distro variant.

As Markus mentioned maybe a more general solution would be to have these things 
as qom objects so that a

qom-list-types

can be used to get all 'audiodev' types, or all 'display' types, or all 'block' 
types and solve the problem this way?

Is there a more general problem / solution that I am not seeing?

Thanks,

Claudio
