In vir-host-validate we do two checks related to IOMMU: 1) hardware support, and 2) kernel support. While users are usually interested in the latter, the former also makes sense. And for the former (hardware support) we have this huge if-else block for nearly every architecture, except ARM. Now, IOMMU is called SMMU in ARM world, and while there's certainly a definitive way of detecting SMMU support (e.g. via dumping some registers in asm), we can work around this - just like we do for Intel and AMD - and check for an ACPI table presence. In ARM world, there's I/O Remapping Table (IORT) which describes SMMU capabilities on given host and is exposed in sysfs (regardless of arm_smmu module).

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
