 Ok. Just to avoid sending one more version which will be rejected. What =
behavior for 32 bits would you prefer?
a) Enable high MMIO by default, owners of old guests will have to add an =
option to disable it.
b) Disable it by default. If somebody wants to use it on 32 bits, enable =
it explicitly.

Kind regards,
