Libguestfs could certainly use this ^.

Also we could use the features outlined in this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1107842#c0

 - If this works: <bios useserial=yes>  (ie. sgabios)

 - If this works: <cpu mode=host-passthrough>

 - Whether the hpet timer needs to be disabled (see also bug 1066145)

 - Whether guests need a <dtb/> element

I wonder if we should or should not expose the version number of qemu
too?  Although it would tempt API users to key features based on the
version of qemu, which is wrong, it's useful for debugging.
