The IOMMU handles communications between the IOMMU and the guest operating system by: replacing, in communications received from the guest operating system, guest domain identifiers (domainIDs) with corresponding host domainIDs and/or guest device identifiers (deviceIDs) with corresponding host deviceIDs before further processing the communications; replacing, in communications received from the IO device, host deviceIDs with guest deviceIDs before providing the communications to the guest operating system; and placing, into communications generated in the IOMMU and destined for the guest operating system, guest domainIDs and/or guest deviceIDs before providing the communications to the guest operating system.
