Abstract
Mechanisms for migration of single root stateless virtual functions are provided. A Single-Root PCI Configuration Manager (SR-PCIM) provides a system image (SI) with possible virtual function (VF) migration scenarios supported by the endpoint (EP). The SR-PCIM may be instructed that a stateless migration of a VF and its associated application(s) from one SI to another is required. Outstanding requests to the VF are completed and any applications associated with the VF are removed from the SI and the VF is detached from its associated physical function (PF). The SWI may then attach the VF to a target PF which may be in the same or a different EP. The SWI makes the VF available to the SI with which the VF is now associated and the SI configures the VF thereby making it available for use by associated applications.
