Mats, thanks for the help so far.

I've taken a look in /tools/firmware. I've grepped for cpu and CPU. I don't
see something obvious to set the number of vcpus for a guest. All of the
code seems as though it ought to deal with the vcpu setting.

Anyway, if you, or anyone else, has a pointer to a particular file I'd be
thankful.

Take care,

Mark
