[RFC] smbios: does it make sense to present some host smbios information to guest?

[Guoheyi]

Hi folks,

Right now some smbios fields are hard coded (like CPU nominal 
frequency), and some can be opted in, but there is no feasible way to 
present real backend hardware information to the front. In some 
scenario, the users of virtual machines may not be happy to see an 
unknown CPU model and 2.0GHz CPU speed, while they have been told the 
backend CPUs are the newest model with much high frequency.

The backend information may be changed after migration from one host to 
another, but in a large cluster it may also be kept in high probability. 
Even if it is changed, we can synchronize the information after a system 
reset.

So does it make sense to present some host smbios information 
(especially CPU information) to guest, by default or by some easy 
option? Or do you have any other advice?

Thanks,
HG
