I looked at that, and it is not trivial.. Both the Intel and virtio-iommu drivers create an "identity" domain out of a paging domain and pass that off as a true "identity" domain. So neither can set the global static since the determination is at runtime.. What I was thinking about doing is consolidating that code so that the core logic is the thing turning a paging domain into an identity domain. Jason
