They are domain architectural state.

Of course, the question is where.

They could be part of the Xen hvmsave blob for the GIC (i.e. along with
the other GIC architectural state such as which interrupts are currently
active,pending,masked etc).

Or they could be part of a new migration v2 record for such things.

With the extension of the DOMCTL createdomain, this would be the best solution. The implementation would be cleaner.

Or they could be part of the hvm params migration record.

And how do you restore? As we may have some default value (such as choosing the default GIC version), how do you know that all the parameters is correctly given?
