| You're adding properties to *all* machines, for something that's only
| used on the PAPR machine. That doesn't seem right.
I tried to figure out about adding these options to only spapr machine, but it
does not seem straight forward as above.

I think current patch will provide a way to help fix the security issue, we
can revise it further if required.
Thank you.
