>   - New 'domid_policy', allowing domain-ids to be randomly chosen.
>   - Option to preserve domain-id across migrate or save+restore.
>   - Support in kdd for initial KD protocol handshake for Win 7, 8 and 10 (64

> +### Changed
> + - The CPUID data seen by a guest on boot is now moved in the migration
> +   stream.  A guest migrating between non-identical hardware will now no
> +   longer observe details such as Family/Model/Stepping, Cache, etc changing.
> +   An administrator still needs to take care to ensure the features visible 
> to
> +   the guest at boot are compatible with anywhere it might migrate.
