An electronic device includes a processor that executes one or more guest operating systems and an input-output memory management unit (IOMMU). The IOMMU accesses, for/on behalf of each guest operating system among the one or more guest operating systems, IOMMU memory-mapped input-output (MMIO) registers in a separate copy of a set of IOMMU MMIO registers for that guest operating system.
