Is there any interest in this series? Aside from copying host SMBIOS
entries, it also seems useful for providing information to the guest
about their virtual machine pool (perhaps via a type 3 entry), or
whatever other bits of data someone might find useful (type 11, OEM
string for instance). Thanks,

Alex
