There at least two cases where the field so far got accessed for PV guests as well: One is in iommu_construct(), via iommu_use_hap_pt(), and the other is arch_domain_create() -> paging_domain_init() -> p2m_init() -> p2m_init_hostp2m() -> p2m_init_one() -> p2m_initialise() It just so happens that the field currently lives in struct hvm_domain at an offset larger than sizeof(struct pv_domain).
