I have to correct this statement: having the dom0 kernel reporting "AMD IOMMUv2 functionality not available on this system" and not seeing vfio groups in dom0 is not the symptom to look for. OTOH /var/log/xen/console/hypervisor.log does show: [2021-09-11 17:04:58] (XEN) AMD-Vi: IOMMU 0 Enabled. [2021-09-11 17:04:58] (XEN) I/O virtualisation enabled So IOMMU is really supported here (running 5.10 on QubesOS 4.1beta here).
