ABSTRACT:
Mechanisms for migration of a virtual endpoint from one virtual plane to another are provided. With these mechanisms, when a management application requests migration of a virtual endpoint (VE) from one virtual plane (VP) to another, a fabric manager provides an input/output virtualization intermediary (IOVI) with an interrupt to perform a stateless migration. The IOVI quiesces outstanding requests to the virtual functions (VFs) of the VE, causes a function level reset of the VFs, deconfigures addresses in intermediary switches corresponding to the VP, and informs the fabric manager that a destination migration is requested. The fabric manager sends an interrupt to the destination IOVI which performs a function level reset of the destination VFs and reprograms the intermediary switches with the addresses of the destination VP. The destination VFs may then be placed in an active state.
