 To see the direction I am going to I attached the first draft version of 
my upcoming multicore patch. This uses the interface provided by 
libxl_cpuid_parse_config(). IMHO this is a very readable and 
maintainable approach, and it can be overridden by cpuid lines (or 
forced again later by being called after the cpuid= parsing).
 
Now actually attached.
Regards,
Andre.
