What's the performance hit to boot time if KVM_HC_PAGE_ENC_STATUS is passed through to userspace? That way, userspace could manage the set of pages in whatever data structure they want, and these get/set ioctls go away.
Also, aren't there plans for an in-guest migration helper? If so, do we have any idea what that interface will look like? E.g. if we're going to end up with a full fledged driver in the guest, why not bite the bullet now and bypass KVM entirely?
