Abstract

Systems and methods for sharing a single root I/O virtualization (SR-IOV) device (106) amongst a plurality of roots (104) are described herein. The described systems implement a method which includes identifying a physical function (PF) and a plurality of virtual functions (VFs) associated with the SR-IOV device (106). The method also include generating at least one set of VFs from amongst the plurality of identified VFs, where each set of VFs include one or more VFs, and generating a pseudo PF (PPF) for each of the at least one set of VFs, where each PPF and a set of VFs associated with the PPF forms a projected SR-IOV device (106). The method further includes associating each of the projected SR-IOV device (106) with a root (104) from amongst the plurality of roots (104) to allow sharing of the SR-IOV device (106).
