An apparatus and method for sharing I/O devices. The apparatus has a first plurality of I/O ports, a second I/O port, and core logic. The first plurality is coupled to a plurality of operating system domains through a load-store fabric. Each of the first plurality routes transactions between the operating system domains and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint requests/completes transactions for each of the plurality of operating system domains. The core logic is coupled to the first plurality of I/O ports and the second I/O port. The core logic routes the transactions between the first plurality of I/O ports and the second I/O port and associates each of the transactions with a corresponding one of the plurality of operating system domains (OSDs) by encapsulating an OS domain header within a transaction layer packet.
