So at the moment my pv guests are getting all zero back from cpuid.  I 
haven't updated their config files at all.  Is that the expected 
behaviour?  It seems a bit unfriendly; I would have expected it to 
default to the old behaviour with no config in place.
Hm, or maybe something else is going wrong?

Thanks,
