Enhanced apparatuses, systems, and techniques for coupling network-linked peripheral devices into host computing devices is presented. A method includes, over a network interface of a host device, obtaining an indication of a peripheral device available for associating with the host device. Based on the indication, the method includes initiating instantiation of the peripheral device into a Peripheral Component Interconnect Express (PCIe) subsystem of the host device by at least emulating behavior of the peripheral device over the network interface as a PCIe peripheral device coupled locally to the host system.
