摘要：
An embodiment of the present invention is a technique to perform address translation. A table structure is indexed by a source identifier of an input/output (I/O) transaction specifying a guest physical address and requested by an I/O device to map the I/O device to a domain assigned to the I/O device. An address translation structure translates the guest physical address to a host physical address corresponding to the I/O transaction.
