You are quickly going to > notice that your performance is abysmal. I don't see any real problems, at least with LPI tables. If the guest changes something, it will be immediately available to us. I don't see any need to seriously validate something, at least here. Pending bit is just pending bit, and configuration is just priority value plus enable bit. But, well, if we think a bit better, in case of pending bit modification, the operations on both guest and host side have to be atomic, otherwise we can clobber our table if, for example, both host and guest modify adjacent bits. And there's no way to interlock with the guest. So, OK, i accept your point.
