USER SPACE PCI DEVICE EMULATION FOR PEER PROCESSES

Abstract:

A system and method include receiving, at a host device, a request from a virtual machine to communicate with an emulated device. The host device establishes a socket connection between an emulator and the emulated device and communicates input-output messages via the socket connection from the virtual machine to the emulated device where the input-output messages use a virtual function input/output (VFIO) message protocol.
