摘要：
One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications while retaining the message vector indication. An I/O adapter event notification may be routed and presented to a host or to a guest that the host is executing. To present the notification to the correct host or to the correct guest, various data structures in host and/or guest memory are used.
