Sorry, what I meant was: this is a property of the _guest_ so should
probably have a save record like other guest properties.  The cpuid info
in the header is a property of the _host_ that saved the record and is
there just for sanity-checking the compatibility of the record (like the
version number).

Cheers,

Tim.
