This patch lacks addition to the RNG schemas that would describe the
elements that are added and the correct values.
Also lacks change to the docs/formatdomain.html.in

The driver should rather be an enum value that is parsed from the string
rather than stroing an inline string. This limits the namespace of
devices libvirt supports but simplifies all matching of the driver later
on.

Atoi is not allowed, use virStrToLong* instead. Also spaces after
function name is forbidden.

Um? Why not virBufferAsprintf(buf, " apic_id='%d', apic_id)?
You won't need the intermediate string. Also it leaks the apic_id
string.
